All. Need some advice. I just put a 93 engine into my 90 truck. Engine sat for 4 years. I’ve got a steady drip from the top of the pump where the throttle shaft goes vertically into to the pump. There is a bit of play back and forth. What can I do to fix that ? Is there just an O ring on there? I believe it’s also sucking air as when I start my engine it wants to race.

    We have pumps on the shelf.     We also have seals.  If that is a an option/ you can determine the part # you need.   There is an exploded view picture and part #s here http:/

  • Not a prob. When parts have hundreds of thousands of miles a reman is best.

Sadly. I would remove the injection pump and see about getting a rebuild kit and replace all the seals including the front seal too so the diesel fuel doesn't leak in the crankcase. Reman pumps are available from @dieselautopower . I would consider that being the governor spring and other internal parts do wear out. 

 

So before performing any repairs I would highly suggest removing the pump from the truck. That cover should have 4 Allen bolts holding it on. Be careful the Governor Spring is attached to the cover and could be replaced but be careful not to stretch the spring. Serioyusly I would just consider a reman'd pump at least then the pump is in good shape to keep running.

I was afraid that would be the way to go forward. Thanks for your input. I’ll investigate a reman pump.
