I am fixing to purchase a 1994 cummins 4x4 5-speed. On the top of the P7100/P-Pump there is the injector lines and delivery valves. What is the metal piece that attaches to the injection pump where the delivery valve goes into the pump? It is cracked and I want to know if it can just purchase 6 of these top pieces and just replace them? It is the front injection line that I noticed leaking through the crack.

Info

Should be able to purchase at injection shop that handles p-pumps.

Delivery valve holder is what you seem to be referring to, any fuel shop should be able to get them from Bosch.

This piece has nuts on both sides holding it down on the injection pump body housing. It is about 1/2" tall and the delivery valve holder goes into it(I believe). Also if I go through a shop they will upcharge it 3x. 

Just go direct to an injection pump rebuilder. Then you get it from the best source and not retailed/ handled/ up charged 3 times. I have mechanical retail shops try charging 1250.00 to rebuild a turbo with nothing but big talk and then I call the injection pump rebuilders and they do the actual work/ get it done for $362,50 in less than a third of the time. It now runs smooth as glass.

 

Talk the price down on the truck you are buying with the cost and time to take care of the problem and then find an honorable rebuilder happy to do it for you. You just have to talk to the right people.

too long of post

You need a plunger and barrel assembly. Buy another pump imo.

If the leak is coming from the piece he is holding, you can get new DV holders.

 

If the leak is from the part still bolted to the pump, you'll need a new IP or send yours to Seth Farrell @ Farrel Diesel Service.  Or some other Bosch shop.
