Fuel System, 2.5d Sofim, 1990

Hi,

My first post so hello all!

I recently purchased a motorhome on a 2.5 d Ducato base.

Very good service history etc. Never failed a m.o.t.

Accept I noticed at speed on motorways sudden engine cuts out - probabl fuel I thought.

Under the bonnet I noticed the fuel filter had been completley bypassed!

Sent it into Fiat, who serviced it , made the same comment, but didn't know how to proceed.

Suggested I took to a diesel specialist.

Before I do this I would at least like to attempt to connect the fuel system up as it should be - the filter has been replaced and inlets cleaned.

Can anybody confirm the order in the 2.5d fuel system?

Is it:

tank--->filter---->pump----->injectors

or

tank---->pump----->filter---->injectors

cheers,

john

Hello
I have the 2.5tdi Sofim 1991. I don't know why your fuel filter would have been by-passed but The sequence on mine from memory is as your second option:
tank---->lift pump----->filter---->injector pump
I cant check at the moment because I am away from it. There are fuel flow arrows on the filter top housing on mine. If you also have them it may help you a bit.
Good luck with it.
Phil

Thanks for that Phillip.

In the end I went for :

tank-->lift pump-->filter---->injection pump

and so far, fingers crossed, my problems seem to have gone away!
