I have Fiat Ducato 2006 2.8 JTD Maxi, it's the facelift model following the vans up to and including 2005 but befor ehte current-ish 2007 onwards models.
Bought Fiat fuel filter, went to change it and they have given me the earlier one in the metal silver canister, the spin on one. Being Sunday can't do much about it.
My model has an all plastic housing with a small cartridge inside. I noticed the housing looked a little damp but couldn't find any real trace of leakage. On removing the old filter noticed that the sealing ring between top and bottom section had stretched and a fair bit larger than the seat it sat on ( to my shame have not changed the filter before, I have left it the maximum 40,000 miles so it's ok that it has grown over that mileage).
Got a pattern fuel filter from Halfords this afternoon and after cleaning the housing fitted it. The new sealing ring was satisfyingly a snug fit on the lip it sits on. Turned on ignition to run the fuel pump and a gusher of diesel from the filter housing where the top plate and filter container meet (at the sealing joint). They are joined by a plastic ring/collar that is threaded and screws onto the thread on the lower housing.
Tried to tighten the threaded ring and it barely moved, but this sometimes happends of coarse plastic surfaces, they bite into each other and grip.
Tried it again and the same leak.
Long story short. Took everything apart and checked that the parts went together nicely. Checked without the sealing ring to ensure the 2 filter housing mating faces would compress the quite hard sealing ring and it could compress the ring about 50% before it met a stop.
Re-assambled very carefully and this time a good leak but not gushing, I managed to get the threaded ring a little tighter.
Took apart again and lubricated the two faces of the large coarse thread, this time only a small leak, a little tighter and just a tiny welling over several minutes of the pump running, switching on and running again etc.
My guess is a design fault within the plastice housings that make up the filter assembly and that this is a difficult fuel filter to seal, anyone come across this before?
We are making a 2 day delivery starting early tomorrow so Rosie goes on the phone to move it all on a day, hey ho.
Thanks
