vacuum pump appears to be going out, I have the seal kit Cummins Kit 4089742, but I was wondering if there is any other kit or parts I can get to rebuild it.

Thanks

use Peter Gould's kit:

Thank you.

I have the seal kit, I just don't know if the seals are all there is or if there are internals to replace.

The kit comes with a DVD showing exactly how to rebuild the vacuum pump -- you could watch the DVD to see if you have all the parts. Alternatively you could phone Peter; he's very helpful and I'm sure would be willing to tell you if you're missing any pieces.

Theres a photocopy of instructions in the Cummins kit. Much cheaper without a dvd. There's nothing to the reseal job.
