    Hi - newbie here. Would appreciate some advice please.

    Fitting a new fuel filter to my 110 Td5 tomorrow morning (bit heavy handed - broke the drain plug on the old one this afternoon - bits of plastic left inside the filter - if you are aware of any 'idiot' adjectives that my wife hasn't already used then do feel free to let me know about them).

    Aware that I will need to prime the fuel system once the new filter is fitted.

    Have read posts on here and elsewhere that say that the way to prime the fuel system is to turn ignition to II, press the accelerator 5 times, and wait five minutes. Have read other posts on here and elsewhere that say this isn't the way to do it - but these don't give details of the correct way (perhaps this tells me what I need to know).

    Anyway - can anybody give me some definitive expert advice on how to prime the fuel system on a Td5?

    Many thanks in advance.

    Best

    Dr Tim

    Pretty sure TD5's have a tank pump aswell as an injection pump so it will probably be a case of ignition on and crank it till it fires

    had mine done on the 24 month service on friday was present when the guy did it he just turned ignition on for a minute or so then cranked it over till it ran as usual .
    must say the tank pump squeled like a strangled cat for a bit till it got the air out the system :D

    [1]turn off the starter switch and wait for 15 seconds
    [2]turn the starter key to position 2 and wait for30 seconds
    [3]turn off the starter switch
    repeat steps 2 and 3 six times
    [4]fully depress the accelerator pedal
    [5]keeping the pedal depressed,start cranking the engine
    [6]continue cranking the engine and as soon as the engine is running on all cylinders ease the accelator pedal back to approximately halfway and release the starter key the engine should now be running
    [7] if not do it all over again
    This is all from the owners handbook but I have had to do it and know it works

    Thanks all for your advice, all sorted now. Jim - your advice suited my (2005) ECU a treat.

    Hi,
    Correct way of priming is, turn ignition on and wait for pump to stop running, then pump throttle pedal fully up and down five times. Pump will now run on and off for a couple of minutes. Key off, throttle pedal on the floor and start.
