Oh what a fun day.
Van started playing up on Thursday, lack of power and not revving out properly. By friday, I only just made it home. Found what looked like a loose pipe on the lift pump, so put it down to that.
Father was supposed to pick up some fuel hose for me this morning, He forgot...... ::)
After fiddling all afternoon, and suspecting every thing, I'm pretty sure air was getting in where the pipes join the fuel filter head. It wouldn't tick over this morning. Tried replacing various pipes, then ran diesel straight into the pump, via the return.........
Put the diesel into the inlet, and it ran fine. I've now changed the filter head for another transit one. I've driven it about 50 miles, and she is playing up again. The way the pipes seal into the filter head is rubbish, it's just designed to let air in, especially as the oil is pretty thick stuff.
Hopefully will get a new filter head tomorrow, and some new hose. Rip the whole lot off and start again.
Is standard clear braided fuel hose compatible with Bio? Not that I'm running bio, yet. Its what is going to go on anyway, but just wondering how long it should last.
-
mate had same probs, 2 things pipe fitings to filter head and the the filter carts ar a biatch to get tight and not suck air...
get a sausage filter in her GM 8) i've done numerous 1000's of miles i lost count so has 6 other cars
-
I've got to have something tomorrow any way, so it'll be getting whatever the motor factors has. I'm a bit concerned about using a sausage filter, my oil is not particularly well filtered and processed, and is often pretty gloopy. I wonder about how many micron the sausage filters are. If I had better oil, I would do it, no hesitation.
The filter cartridges are tools of things, possibly it was air getting in through the filter seal. I had to fiddle with it a few times to stop the fuel leaking out. I guess the thick oil has brought up an existing problem. Its been spot on up till now, but looking at it now, there are so many different places for air to get in, it seems futile trying to find which one is the culprit.
When she is cold, she runs ok, so I'm guessing as she gets warm, the rubber and plastic becomes softer, and starts letting in air. Chuck the whole lot in the gutter and have a fresh start I think. There is an outside possibility there may be a blocked tank strainer. I've blown back down the pipe, and there is good flow coming from the lift pump, but its futile trying anything till that filter head is sorted.
-
on my first twin tank i had air problems, when cold all good, hot was bad for air, so when it was hot i did up every jubilee clip even tighter (easy when pipes hot) she was good to go then...
-
Good tip, I'll remember that if I get problems. I'm thinking to put a smear of silicone around the pipes before I join them anyway, just as an extra precaution.
-
Just out of curiosity, is there any reason why the return should go through the filter head?
The only reason I can think of is that it is for when there are two filters fitted, to balance out the flow between them both. Maybe that is it.
-
2.5di ?
did you use a ford filter ?
get a ford filter and try again.... surprising what a difference it makes!
-
I've been using Marle filters. The whole lot is coming off anyway, providing I can get a replacement tomorrow. Thanks for the tip though. Never had a problem up until now though.
-
I know it sounds daft... but I had problems myself and someone told me to try a ford filter... I did out of an act of desperation and it worked...
I've seen the same thing loads of times on the transit forum too :-(
-
In all fairness, I would try it. Its just that I need the thing going as soon a possible, and dont want to take the risk that the pipes going into the filter unit are leaking. I've got a chance tomorrow for someone else to pick the parts up for me, so I think I'll just go the whole hog and be done with it.
I wouldn't be surprised if half the problem is caused by thick veg, and the ford filter head just doesn't inspire me with confidence. Chucking some diesel in on top did help a little bit.

always wondered this? my view was it uses return fuel, less needed from main tank on sucking up, and maybe it uses heat from going through engne to warm fuel back in?
to me this causes probs as air goes back to filter head, adding more air to the other air being sucked in, just jion return pipes up and use feed in as normal, may cure all the probs?
-
wait.... does your engine not have a lift pump on the side ?
if the filter is leaking, it should be under pressure, so should be letting fuel out not air in ?
-

Yes, it does. Like you say, it should all be under pressure. I can't quite fathom that one myself. All I can say is when I put the fuel direct from the lift pump into the injection pump, it ran fine. As soon as I replumbed the filter, it wouldn't run at all. Now the replacement head and filter is playing up.
I can't see that it has for some reason started blocking filters solid in a few miles, it's never blocked a filter before. It's the third one on there now.
Bit of a mystery. You can't believe how much trouble it is to get a filter head with the unions. Must have called half a dozen places. Some of them don't even know what the unions are when you explain it to them.
Even if the pipe from the tank to the lift pump had cracked, surely it would have had the same effect when I by passed the filter.
-
could it be the feed or return line being blocked ? could try blowing down them with an air line ?
the return line has a little float velve in it where it goes back through the filter... if there's fuel in it, it can duct back into the filter... if it's full or air it goes back down the return line
it could be the pump on the side of the engine... they only do about 50k miles before giving up... normally they just stop all together but it could keep going but low flow/pressure ?
you could take the pipe off it and have someone spin the engine while you look for fuel squirting out
(it should pulse... squirt, squirt, squirt etc..)
clear braided hose will go hard after a while on bio or veg, you could use it as a stop gap but proper rubber hose is better
you might be best off replacing all the fuel hoses for new just to make sure.... if you do... go with a bigger size too, it's surprising how much difference it makes
-
I've blown back into the tank, that seems fine. There looks to be good feed coming out of the lift pump. As far as I know, it is the original pump, with 120K on it, so could be the next line of enquiry. Maybe it is loosing pressure when it gets hot.
I've now put black rubber hose from the lift pump, into a cheapo inline filter, and on into the injection pump. I've joined the returns with the same stuff. I'd just about got fuel to the injector pump, and the battery went flat...........
It's on charge now, so I'll try it in the morning.
It was running ok ish when I got home last night, went to start it this morning and it just died, so I gave up. I wonder is the lift pump letting the fuel drain back into the tank, when it is hot. Maybe it is dogged.
Cheers Knighty. I'll get there in the end.
-
you useing a paper inline filter? they implode under oil use... may last abit...
has your engine got heater plugs?

was this on diesel only?
-
No heater plugs. The filter is a slightly better one, with a plastic gauze in it, just for test purposes. The fuel comes into the gauze, not like the paper element ones. I've got a mixture of dino and veg in the tank, probably about 50/50.
The more I think about it, the more the lift pump seems suspect, although it stlll doesn't alter the fact that the thing wouldn't run at all with the filter housing plumbed in, but ran fine when I took the feed directly from the lift pump to the injection pump. Effectively it is what I have done now, just with the inline filter in the pipe.
-
hmmm just seems odd it wouldnt start in the morning with the new inline filter.
your ip pump may suck fuel by itself i knew a 300tdi with a dead lift pump and it had been running couple years like that...
is your the turbo or non turbo? do the non turbos have lucas pumps?
-
The battery went flat before I had a chance to start it with the inline filter. This morning it was still on a replacement filter setup.
-
turbo has a Lucas pump, non turbo have bosh pump, there's a few (very few) non turbo with a Lucas pump but they're easy to spot, they have an electronic throttle, all the bosh have a throttle cable
you could also check the cold start advance, there's a little bump sticking out the side of the pump slightly towards the front, it has a little leaver on it with a ball on the end which fits into a little arm with a cup on it (for the ball to fit into) iirc it's held on by a 10mm not
there's a few seals in there which can go and let air in... normally they don't leak unless you've had it apart... but maybe the veg could have damaged the seals ? - you can get a kit with all the fuel pump seals in it for about a fiver
iirc the lift pump is only about £17... I was always surprised how cheap they are, I used to keep a spare on hand, came in handy when we were doing loads of miles at work :-)
-
I've just had a look on Ebay for lift pumps. Like you say, around 15 to 17 quid. I was to scared to look, I thought they would be up around £50, which does kind of suggest they may be quite a high seller.
I can get my hands on a second had one but it's not worth the bother for that sort of money.
It is definitely the next suspect, I'll order one in the morning. It makes sense really. Ok when cold, fills the filter and pumps ok till hot, then lets the filter drain back into the tank overnight, if that is what it is doing. Wouldn't harm to put one on there anyway, just to eliminate it from the equation.
-
just to make ya feel better grease, I spent good while this afternoon with similar on my old transit, got it starting now(had to resort to a sniff o easy as battery was dying but now won't rev much past tickover, and with flat battery had to keep waiting for the charge to build up from jump leads, at least it's running now though, but will have to wait til w/end now.
I'll try bypassing filter next too.
Hope you get yours sorted mate, at least you know it's ok when filter was bypassed
-
It lives! I think.
Battery on charge last night, failed to start it this morning. Pulled both batterys off and charged them.
Tonight, I ran a feed direct to the injection pump, and it fired up fine. Swapped a scavenged lift pump in, and joined up the cheapo inline filter, and started no problem. Just ran it 25 miles, and felt the best it has for a long time. nice clean pull in high gear from low revs, and plenty of power up the hills. I'd put a bit of loss of performance down to bad oil. Seems now as there may have been a developing problem, and this was its last gasp. Still not to sure if it was the lift pump or the filter. I've got a new pump on order, and will sort the filter out soon as.
Many thanks guys, you've been a great help. I'm fairly confident now that it will be fine in the morning.
As a point of interest, I charged the drivers side battery, and this morning it was still not up to full power, or so it seemed, so I put it back on charge. Then it occurred to me to try the left battery in the right tray. That was equally as flat as the one I put on charge last night, so i left them both on charge all day. Kind of suggests that either it uses both bats to turn the starter, or they join when the power gets below a certain level. The starter will operate with the right hand battery alone, but not the left alone.
Thrilling innit? :P

That is pretty much what mine was doing Chug, it would just stay on tick over, and not rev up. After my little palaver, I would suggest running diesel from a can, straight into the injection pump. It is the pipe at the front of the pump, not the rear. If she runs ok then, you know it is filter or lift pump.
I've been told they self purge, but I'm not so sure. You will see a bleed screw on the side of the pump. Open this and spin her over, then crack open an injector.
I would have to say, with the benefit (trauma) of my experience, suspect the lift pump, even if it looks like its shooting fuel out ok. I can't be certain, i'm still 50/50 if it was that or the filter.

so GM your not quite sure what started ya probs, i hate when it runs good again but cant decipher what the problems were... always leaves a niggle in ya head...

Update.
I have now put a new filter head on. Piped it up and its all working a treat. Looking at the filter head, there is absolutely no reason for the return to go back through the head, so I have just joined the pipes together. I guess the only reason the ports are there is for a dual filter setup.
On a side note, if the return ever came adrift, then it would probably empty the tank onto the road in a few minutes. The way it is made, the quality of the pipes and fitting, you would think that it was a cheap cosmetic after thought, not an essential piece of pipework.
I've still got the second hand lift pump on. It's working so it may as well stay there. I'll carry the new one in the van, it's only a ten minute job to change it anyway.
Cheers folks.

Lets play a nice game of spending every weekend sorting fuel problems out, in the pouring rain.
Oil gone way to thick in the tank overnight now.
How do you sign up for the one way trip to Mars?
-
after spending a day in a ditch covered in diesel and mud i can feel for you. i had loads of problems with the fuel filters on the minibus. in the end i got one of those priming bulbs that look like lemon and a filter for a defender. i have had the filter on for a couple of years so far with no problems. here is the ebay link.

im still on a sausage filter :)
-
Photoman, that is identical to the filter housing I have just fitted. I went to drain the tank, it's coming out as thin and as clear as you like.
Looks like the element has blocked in around 200 miles or so, with a thick gunk.
I was on the way to get some more elements when I conked.
I know I'm risking it a bit with the oil I'm using, but I didn't think it was that bad, maybe my filtering setup needs new elements.
I've started putting the inline filter back in now. Run out of hose clips, so will have to pull some off some scrappers tomorrow,
I've just bought a load of stuff to make a processor. If I wasn't pratting about with crap oil, I'd have the cone and legs on a drum by now. I just haven't got good enough oil to run on it any more.
Can you pull the element out and clean it in your sausage filter RM? Can you pop a link up to which on you've got? I see one with a glass bowl, that can be pulled apart, for about 6 quid. Only 40 mic though, but I guess I will just have to risk it. The inline I've got isn't going to last much longer.
-
could it be the in tank strainer blocked ?
the newer (2000 and on) transits don't have them but I'm pretty sure the older ones do ?
-
The way the lift pump pushes the oil out, i doubt it. There is good pulsing flow. I put a pipe on it hoping to empty the tank. There was no need, the oil is fine.
I'll refit the inline filter tomorrow.
Is the tank accessed through the floor, or dropped down from underneath. If it is accessed through the floor, all the racking will have to come out, to get the floor ply out. Might just cut a hole in the ply if I need to.
Then agian, maybe the thick gunk is coming off the strainer itself, especally now it has got warmer, it may have collected, and is now thin enough to go through.
-
i dont clean them, never needed too, you can get 5x for about a £10 off ebay

i think these sausage filters are about 40m, seems to be just right for 100% veg, 5m or 10m are really for diesel and its asking alot to push veg oil through a small micron like that... you will get strain on the fuel feed and blocking rapid.... thats why i changed and i gambled and never looked back, me and alot of friends too!

If it's any help, the micron symbol can be had by typing Alt + 0181 ... µ

I can see your point about it being a bit much to push veg through a 10mic normal diesel filter. Dunno how it has lasted up till now. I guess my pressurised setup aint quite cutting it. My inline is pretty dirt, after less than a thousand miles.
Thanks for the offer of the sausage filter, but by the time I get it off you, I'll have got one delivered anyway. I think I will go for one of those glass ones, so it can be taken apart. I'll order it now in a bit.
I'm just going to have to put some late shifts in and get on the bio. Pratting about trying to find liquid oil is doing my head in. I'm forever fooling with the filters.
Done it. Ordered this one.

it wasnt a sausage filter i have, its the second picture the glass / chrome split apart to clean filter one, i have never used it as sausage ones keep going, they work bang on... keep the bits out and car running like a new filter everytime...
but alas i think you already ordered a glass one :(
also surface area on these split apart ones isnt big at all (inch? of mesh), infact tiny compared to an original and 6 inch sausage

My mistake, not to worry.
There are two sizes of the glass ones. I got the bigger one. I'll give it a go anyway. If it fails, I'll have to try the longer sausage ones.

tank comes down from underneath
I'm surprised you're having problems
you could try removing the return pipe and see what the flow is like, and/or the coming out of the filter
I'm starting to think maybe fuel flow/pressure isn't your problem :-o
-
When I run a feed into the injection pump, she cracks up and runs, sweet as a nut. I ran a feed and the return into a gallon can today, and it was fine.
-
that's...odd
any air in the return ?
-
It lives again. I think the oil i have in is so dirty its just clogging filters like fun. Either that or a temperature drop let whites precipitate out into the filter. Either way, its just done 20 miles without a problem. See what the morning brings. Chucked abuot 2 gallon of mis fuel in now, so should help a bit.
-
do you have a fphe fitted ?
even if the oil you use is ok most of the time... on a long trip it'll warm up the thick stuff in the tank and use it up
-
No FPHE. Would really like to have a heated tank and filter or block heater. Time time time, where does it go?

I'm considering getting a large version as a final filter from settling tank to storage.

the only thing with these type filter carts is when changing one you drop all the fuel everywhere as the cart is polo ring shaped and the bowl is full of fuel to, messy game...
-
Interesting. I've never used one, but it gave me ideas for a hydrocylone (that I've built, but have yet to try) and a multiple 12" standard water filter type setup.
I think we're a bit OT here. 8)
-
I always found the dual bosh filter heads made a massive difference... less than half as restrictive and the filters last more than twice as long too (fuel goes through them in parallel)
but the place I got them from doesn't have any more... they were only about £15 each iirc
I googled and the first picture I found was my own :-o

An interesting looking bit of kit, and judging by some of the certifications, it looks as though they should do what they claim to do.
I wonder just how much contamination they would deal with? It looks as though they drop the water and contaminants into chambers in the bowl. Not over priced either. I got quoted around £50 for a normal CAV landrover filter, ( From a landrover main dealer....Muppets,Bought an identical one for £20 after.)
I wonder how much elements are?
-
Elements are about £10 each.
I love the twin Bosch setup. Hmmm...thoughts are brewing.
-
if you find any of the dual bosh filter heads anywhere lets us all know... last time I wanted one I couldn't find one anywhere...
it's amassing the difference they make.. I've used them on single tank and twin tanked vans, I'd had single filters on both before and noticed the difference straight away (even with lift pumps fitted which you think would cancel out any restriction)
plus, if you get Iveco filters, they're bio/veg friendly, filter down to 4 micron, and have some kind of special water absorbing gel in the bottom... for £4 a time if you buy half a dozen and ask for a discount :-)
-
I've found a few - cheapest one is £125 though!

Dual filter heads do seem to be thin on the ground. To be honest Knighty, I think the way it's done now is to put two singles together, which is why the single filter heads have four ports. It makes sense really, only one casting to make.
I had a look at the one I got, and it does seem possible to join them up either so that the fuel goes through one filter, then through the next, or, so the fuel is divided equally between the two filters, if you see what i mean.

good spot, by the same token could jion 3 or 4 hmmm

yeah I know what you mean... guess you'd need a little bit of pipe in there so one of the fittings can swivel to tighten without unscrewing the other one :o
shame as the last dual ones I got were only £15 delivered :o

If your using Banjos, tightening them up without twisting the pipe is not a issue. Maybe have one hose tail, joined by pipe to a banjo. The banjos seem expensive. I'm sure there are water fittings that will fit, for a lot less money.
Could definitely join more than two together.
Getting banjos that come out on a 90 degree would be better. The ones I found were all straight.

Is this any good Alan? Same idea, different filters.

It cheap, but it does need two bowls, and the bolts and washers to attach them. Haven't looked at the prices of them yet.
Needs the filters too.
Bowls £4.79 inclusive
Bolt £4.20
Still cheap enough. Roughly £28, plus filters.
Very cheap actually. My single was £25

yeah true all adds up
-
They do a complete unit for £24

That looks a good co. That is who I had my parts off. They don't show half that stuff on E bay.

the problem is they only do the Lucas/cartridge type with the bowl on the bottom (which makes loads of mess when you chance a filter, plus it's a bit more fiddly)
the bosh ones they used to do are the type where the bowl on the bottom is part of the filter, so you just twist one filter off and twist the new one on, no mess etc..
I got a twin bosh one from them before.... and emailed them when I needed another but they didn't do them any more :-(
