Question Leaking injectors

Hi everyone i, first off have to say that i am fairly mechanically inclined but i do not know much about diesels. The other day i looked at my injectors and they are leaking diesel onto the intake manifold. This seemed to happen after i turned up my pump, but i did not turn it up much and i have a pyrometer and all is good there, so i just think the seals are worn out. The only place i can really find the parts i need is here. 1991 FORD F-250 SUPER CAB Fuel Injector O-Ring


Now i dont know if that is a good price or not so any input would be awesome, and would it be a good idea to replace the injectors while i am at it? Thanks and once again im not good with diesel matenece so any help or input would be awesome

I agree with the o-rings. Be sure to remove each line separately.


I'M KIDDING! Remove it as one piece. I got a call the other day asking how each line came out!

They do as far as I'm concerned. But apparently that doesn't stop people from trying craziness.

Sounds like you advanced the pump 2 maybe 3 teeth. Sounds fine.
