Does Cummins sell a seal kit for a 94 vacuum pump?
If so, what is the part #?

P.O.R.

I was hoping to find something cheaper.

If you can reuse your o rings ( I was able to) you can get a seal from an industrial suppy house like Kaman, etc. The seal you are looking for should be made of Viton material an is 28x38x7 in size. Should run you about $10.00. You can check with these folks to find a distributor that is close by.



International Seal

In case you don't have them here are great directions for the repair.

Vacuum pump seal

Good luck, Frank.

You can get the o-rings and seals matched up by a good partsman for under $20. The same parts come in the Dodge seal kit for over $100.

If your a TDR member look up member ID CPFF. I believe he was the first to develop the seal replacement kit. Didn't cost too much neither - from memory something like $30ish.
