There is a hidden heat exchanger under the Peugeot fuel filter. This page details how to modify the filter housing to permanently heat the fuel using the heat exchanger. The heat exchanger uses engine coolant, typically 70-80°C, which is fully passed on to the fuel.  There are also many points where air can leak in, and fixes for these are also detailed.

for people who dont know about or seen the heat exchanger under the pug filter this is what it looks like.

ok re: my air intake issues on my pug 405 i have narrowed it down to MAINLY the heated filter, now this filter has many points to leak at as you will see from the pictures that follow, and this is what i did to help solve the issue.

points to note is i have taken out totally the stat that controls flow in the filter so now all oil/wvo has to go through the HE before hitting the filter hence getting maximum temp the engine reaches 70/80c which is nice, and passing this heat on fully to the oil, when the stat was in i think when hot it stopped the fuel passing through the HE and let it go into filter first.

check the picture with my one pence "PENNY" trick ;) this totally blocks the fuel going to filter and makes it go down through HE first to heat the oil constantly! :) basically making the HE inline aswell as the filter inline after the HE, instead of the stat combining the HE filter.
+
Note that the OEM system initially heats the fuel with the coolant, then when hot a stat bypasses the heat exchanger and delivers fuel straight to the filter.

now this is where it gets interesting, i took the guts out the stat and cut it shorter and added a penny into the hole to block off the fuel going into filter, now fuel has to all go through the HE then up into filter, also i silicon sealed this sucker in as this o ring was pants to.

and this is as far as i got, i sanded the base ready to fit and silicon seal tomorrow with the oring back on car, got to dark outside so couldnt finish it, going to sand the HE area too to make the both faces mate nicely with sealer and o ring :)

There is a hidden heat exchanger under the Peugeot fuel filter. This page details how to modify the filter housing to permanently heat the fuel using the heat exchanger. The heat exchanger uses engine coolant, typically 70-80°C, which is fully passed on to the fuel. There are also many points where air can leak in, and fixes for these are also detailed.

Applicable vehicles

  • Peugeot
    • 205
    • 306
    • 405
    • 406
  • Older Citreons
  • Some Fiat Ducato vans

Modification

Note that the OEM system initially heats the fuel with the coolant, then when hot a stat bypasses the heat exchanger and delivers fuel straight to the filter.

Rotary-Motion has come up with a mod called the one pence "penny trick" - this blocks the fuel going to the filter and makes it all go down through the heat exchanger first, heating the oil constantly.

Heat exchanger
Mating face of the filter/stat housing
Water sensor
The parts that make up the stat control, which are to be removed.
This is the bleed off valve for water in the fuel. There were issues with this sealing, fixed by adding an extra o-ring.
By cutting the innards of the stat short and adding a penny into the hole to block off the fuel path directly to the filter, all the fuel has to pass through the heat exchanger first. This was also silicon sealed in, as the o-ring alone is inadequate.
The top of the stat, also silicon sealed in place
Water sensor silicon sealed in
This is where the oil goes down and through the heat exchanger
Both filter base (and heat exchanger surface) were sanded before refitting with original o-ring and more silicon sealant to provide an air-tight seal when refitted.
