Hey guys
Can anyone help me or suggest a fix for my leaking diesel injection pump. I have a cruiser 1 hz non turbo model. I am new to the diesel engines but really dont want to take it to someone as it will probably cost an arm and a leg. Is it possible to re-seal an injection pump myself? I have been told that in order to do this myself i need special fuel pressure gauges etc to get the pump back to operation....or is it a matter of taking the injection pump out re-sealing it and putting it back in??? Or the 3rd option is i take it to someone and bite the bullet. Any help on this would be appreciated.....Is it a common thing for these pumps to leak????

Where is it leaking from? Is the 1hz an older moter?? If so, it will need a reco more than likely. The old pumps don't like the low sulpher deisel. The seals dry out and leak. I've had 2 trucks with the same problam. Sorry! Get it checked by someone trust worthy. Most deisel injection specialists are OK.

Cant exactly see where its coming from its somewhere on the top half at the back of it.....i have heard similar things in reqards to the new bio diesel that it stuffs the seals etc....do you think it would be expensive to recon the pump?

How'd yo go with your fuel leak problem Sargmeov? I'm in the same predicament and thinking of pulling off the pump myself to save costs!

I'd say all was good after the repair since it is 2 years ago, but back to yours, a word of advice, do not pull your pump off and do the repair yourself just to save a few bucks, it will cost you more in the end if you stuff it up, you also need to ba able to reset the pump timing.

Unless you really know what you are doing I totally agree with Croozza.

Pulling it off is the easy bit but bolting it back on correctly has the potential for things to go wrong and may cost you a lot more money than was saved by pulling it off.

Hi all yes it went fine i narrowed it down to the hunter screw which was leaking so i carefully undid it with out altering the threaded rod in the centre and took it to diesel mechanic to have new seal put on it cost me alll of $4 and i put it back on no more probs

it actually sits on the back of the pump facing the fire wall......it has a 13 to 14 mm bolt onto the pump with like a adjustable screw that locks off down the centre of it......if your not sure what your doingi dont recommend playing but the way i figured it was what did i have to loose either way at worst it would get rebuilt and it was going to cost.....in the end i got lucky i think something simple as a pressed on o ring for $4.....good luck
