    Diesel fuel filter change 2.5 V6

    Does anyone know the best way to change the filter?
    Every time I change mine the car is a real pig to start, it fires, runs for a few seconds then stops and wont re-start.
    I have tried prefilling the filter with diesel, cracking the feed pipes to the injectors whilst turning the engine over but the only way I have found is to have another car alongside with some hefty jump leads and just keep turning it over and over for what seems like an age.
    Its almost like it doesnt want to start.
    Please help as I'm doing a service before next weekend.
    Thanks

    It sounds almost like your getting air into the system, through the fuel filter. When taking it off try plugging the fuel pipes with the existing clip or jubilee clip and once you've put the new filter on and connected up the pipes make sure the clips are on properly so no air can get into the system! leave the igniton on (but don't crank the car) for a couple of minutes and then try!

    Good luck i say.
    Things to do: Lower on coilovers, spacers, front end respray and a full correctional detail!

    Be carefull when you take of the plastic valve with the R clip, it is very easy to break the pipe coonectors off.
    Make sure you lever the valve from its base near the filter, DONT pull on the pipes or the pipe connectors or you will be sorry.

    You dont need to change the valve unless it breaks.
    It will only break if you happen to stress the pipe connections.
    Just take the R clip out and pry the valve out from its base.

    Good thing you did as the seals on the plastic tee valve will need replacing anyway so you wont experience poor starts due to air entering the system...
