Multijet?
Yes, all Diesels have a fuel filter.

Re: Doblo 1.3 multijet oil filter
Hi mate... here is a quick guide for you
1. Undo the fuel filler cap to de-pressurize the system.
2. Disconnect the electrical connector at the top of the fuel filter (Pre-heat device)
3. Disconnect the 3 rapid fit fuel line connectors. (remember which one goes into which port) ((just squeeze the two bits in and pull))
4. Undo the 2 13mm bolts that secure the filter assembly to the bulkhead
5. Slowly lift the filter assembly upward to reveal the water in diesel wiring connector at the base of the filter. Disconnect this.
6. Take the whole assembly out of the engine bay.
7. Unscrew the top of the filter assembly to reveal the filter inside.
Hope that helps,
Alan

Re: Doblo 1.3 multijet oil filter
Chances are mark that fiat are the only ones to make the fuel filter the one for 1.9 multijet is £53 and NEEDS changing at every service as I'm sure so does yours.
Pound wise and penny foolish!!!!!! repace your fuel filter and air filter in line with your service schedule as both are as important ,as your oil and oil filter.
Fiat dealers aren't ripping you off its the price Fiat put on there parts listed price is about £ 29 you can get it cheaper at www.shop4parts.co.uk but there is a carriage charge which negates the savings.
if its a struggle any small quality independent would only charge half an hours work to change a couple of filters.
Hey Ant,
Thanks for the info on changing the fuel filter. I've had a change of mind and decided not to do it after all.
I just come back from my local Fiat dealer ( stand and deliver !! ) The good news was they had the filter in stock, but........ they wanted £30 plus vat for it. I looked at it and it was just a paper thing. There is no way I'm paying that. I told him what he could do with his filter !!!
Why is it that when it says main dealer part, you get that feeling that you are about to be ripped off !

It's a good idea to prefill your new fuel filter with diesel first, this saves introducing air into the fuel system and airlocking it up.
You need a little diesel first, so:
Pull the fuel return line off the old filter, this is the pipe FROM the injectors that returns the spill off back to the filter (usually a narrower pipe than the other two)

Bung up the port (hole) left in the old filter with one of the little rubber bungs on the new filter.

Stick the end of the free return pipe in a clean, dry container and run the engine until you have around 1/2 a litre.
It's tricky, but you need to fill up the new filter with diesel through one of the holes (I use an old syringe with the plunger removed as a funnel. You can also add a dash of your favourite fuel system cleaner to the filter as this time)
Then fit the new filter, there should be no chance now of pulling air through and locking the rail or injectors.
If, on the off chance you do lock it up with air and repeated cranking won't shift it (which is doubtful as the injector return is looped back into the fuel filter)
You can use a hand pump/vacuum pump to draw fuel through via the return pipe.
or
Slacken, ever so slightly the union to the injector furthest from the pump and crank it over a little until fuel leaks out of the loose connection, tighten it and it should start ok.
(this last one needs a note attaching, the fuel rail at crank will have around 300 bar pressure of fuel in it once the air is out, so only undo it enough to allow the air to escape and flick the starter over in short bursts)

Many thanks for this Goudrons, I posted a similar request in Technical regarding the Fiat Fast Change Fuel Filter (55702102) fitted to my 2011 MJTD Qubo and Sludgeguts pointed me here. My filter has the electrical plug on the bottom and the three pipes you describe on top, along with a nipple. I guess this is to fill the filter or purge air?
