Thanks, I'll use that part number and see what I can get. I close friend of mine says that Cummins has re-manufactured parts including lift pumps that work as well as new stuff. I'll find out.

The throttle control can really become an issue. Mine never worked properly from the day it was new. Left me in trouble several times.

As far as I know this is the only person that can fix them:

His name is Steve Boler. Be real nice to him and maybe he will sell you a spare. He rebuilds them completely which is not cheap but then neither is next day air back and forth. I used the spare just once. Nice guy and you can download a bunch of test procedures from his webb site.
