Cummins ISC 330 Fuel Lift Pump Leak

Recommended Posts

We have a 99 Monaco Windsor,and after the lift pump primes the system it has a small leak up around the top of it.Leaves a small spot in the driveway. wondering if the gasket can be replaced?

Hope someone can help me with some info !!

Thanks,

Most just replace the pump complete-- a well known problem.

But, you could check with Cummins to see if a seal kit (O rings) is available.

We are going to be looking at a 2001 HR with the Cummins ISL 370. Is this problem only on the 330 or other models also?
