Hello all, I haven't found where to introduce myself here & I hope this is the right place to ask this question.
I have used waste veg oil in my cars for many years, filtered at various times via socks or water filters down to 1 micron.
Currently I'm running a lovely 98 Merc C250 TD Sport, & have been advised never to let it go below ½ tank full. It runs beautifully. I know from whispers that people known as Spock & Chissel(sp?) successfully connected the tank halves with a sump modification, but I haven't found details.
I'm thinking of drilling a hole near the base of the upright tube in each sender unit, inserting tubes to hold the drain valves open, and connecting with a T so that both run to the main fuel feed.
Comments please?
Cheers, Phil

Hi Phil and welcome, sorry to say its a bit quiet on here at the moment, hopefully someone who can advise you will see your post.

Thanks -sadly, many forums seem to be this way now, probably as people gravitate more & more to social media - I fear that a lot of information is to be lost in this way, I'm not sure ...

Unfortunately Spock and Chissel didn't migrate across from the VOD. The information you require is locked in that forums archive that cant be accessed now. Shame.

This has apparently troubled many people (not just veggers) if looking at the various fora is anything to go by, and now I've bought a second-hand sender the solution seems so simple that all my head-scratching is ... comical. Of course, I could be wrong and if so I'll let you know, though the post I write may be unpublishable for the cursing.
On both this & the left hand sender already on my car I'll remove the internal feed tube & cut the black plastic tube which leads to the external feed about 10 mm above the base plate, fit twin left-hand senders, & link them with a T barb to the normal feed line.
