Can someone please help me with this or point me in the right direction? I have a 1990 Cummins with a rotary injection pump it has started to drip fuel at the rear of the pump. It looks like it is leaking between the pump and the block which has the six fuel outlet ports, this looks to be bolted to the injection pump by four or five torques bolts. Is this an easy fix? Do I have to remove the pump? Thanks

 

It happens. First try tightening the bolts that hold delivery head on. If that doesn't work, you will need to remove the head and replace the o-ring.

 

THANKS,
Tried tightening the bolts first thing and it still drips. So do I take the bolts out and the head just comes off and that is it or is stuff going to fall out....... I have never ever been in one of these before. Can a simple ol' shade tree mechanic do this?

 

These instructions will take you through a complete reseal of the injection pump. Sort through the information to find the deliver head.

Dont know if you got the leak fixed but if the injection lines have been off recently dirt could be in the threads causing a leak. Mine did this.
