    Re: DIESEL PUMP FIXES TO AVOID EXPENSIVE REBUILDS AND CURE LEAKS!!!!

    Hi All,

    We have a 1992 LiteAce with the 2C turbo diesel. It runs great but recently developed a fuel leak from what looks like the return relief valve on the back of the pump. I tried to get a picture of it here:

    Has anyone dealt with this before? Does the relief valve fail? Or does this indicate some other problem with the fuel return?

    Any help would be appreciated.

    Thanks in advance,
    Blake

    The seals I've mentioned above though are all well with in grasp of any hobby mechanic!!!
    Looks like I get the pleasure of following your tutorial today! I have a suspicion that my leak is coming from behind that distributive head. In the diagram it looks like you could just remove that head and swap the ring with the pump still in the vehicle. You mention that the pump would need re setting up though. Any insight on that part? If it's just timing the pump, that doesn't seem too bad. I need to track down that tool though that measures plunger depth or whatever it is.

    Thanks for posting all this though. It's a huge head start!
