Engine/Transmission (1994 - 1998) Lift Pump P/N

[KennyM]

I've got a pretty good leak around my lift pump. If I prime it while holding my hand under the pump I can fill it up with fuel. Can someone give me the LP P/N, and the P/N of the ruber hose between the LP and the pre filter?



Also If you have ever changed the LP any tips. How does it make contact in the moter. Does it just pull out once the bolts are removed?



Thanks, Ken

KennyM,



If the push button is leaking, the O-ring to fix it is about fifty cents at NAPA. You don't have to remove the lift pump to replace it.

 

[KennyM]

JOE, I'm not sure it's the Push buttin. I just used it to build up pressure so I could find the leak.



Lethlisb, Thanks, that the P/N I wanted.

 

[Joe G.]

The push button can leak like crazy and still work. The O-ring that leaks is the outer one.

 

[KennyM]

I just got back from Cummins with my new one. I will rebuild the old one later and throw it on the shelf.



Thanks, Ken

If you can find a source for the check valves please post it.

I got here late, but for future reference the lift pump is cheaper at Case tractor.

 

[Cooker]

Be carefule because the Case LP will not work as a replacement for everybody. On my 1996 the one fitting that needed to be swapped between the two was not interchangeable.

Now you have me wondering if the LP I've been carrying around as a spare for the last few months will work. I'll bet I won't be able to tell just by looking at them will I?

 

[Cooker]

You can tell by looking at them. Here is a picture from the link I posted above.

I'll check it out in the morning. Thanks

Cooker,



The fitting on your pump looks like a nut on top of a larger nut. Mine looks like one large nut so I'm guessing it will work.

You don't happen to have the Cummins Gasket P/N for the lift pump do you. I go tit all taken apart, went to get the gaskets out of the bag and realized I had the Banjo washers. Should have checked that while at Cummins. Thanks.
