Ford fuel priming hose and valve

    Been taking a look at a few jobs on the new diesel fiesta. The fuel filter change is apparently a bit if a pain to get at, but that's not my real worry. I have had a mate just been off the road several days as he could not get his diesel to prime and bleed. It just would not re start. The more I read on line the more similar tales I heard.

    Also the official Ford priming hose with different adapters is £250!!!
    I know there are cheaper versions out there but again I see horror stories of wasted money and kit that wont fit, alongside tales of simple ten minute jobs??

    Anyone else here replaced the fuel filter on a Fiesta tdci, or anything to say that might be of help.

    The biggest issue is the sharp edges of the metal fuel filter cutting, damaging the "O" rings in the pipes.

    Once they go it is a nightmare to fix or replace them. If it happens trace the hoses back to the metal supply and return pipes and fix new rubber hoses.

    Check the filter, buy a decent one, not some cheep after market rubbish. The hoses are easy enough to disconnect, just pull off in a straight line and refit in a straight line.
    Do Not wiggle them on.

    If tackled with care it is a 20 min job. 10 min if the clamp bolt does not fight back.

    done hundreds, you can get a fuel primer pump /bulb of eBay cheap, change filter connect supply pipe from tank, suck fuel out from filter, re connect other pipe and start and hold revs at 2000 rpm for a few seconds in case any air is left

    also if you have an air compressor you can use a air brake bleeder to suck fuel through

    Before I had a suction pump I would always fill the filter with diesel first. Now I just put the sucker on and draw diesel from the tank piece of cake.
