Lift pump jitters. Pulled off the hiway to have the drop in fuel pressure (15 to 7psi) checked while traveling cross country. While at the Ft Worth, TX, Cummins shop I learned that Cummins consider anything above 3psi as acceptable or within the normal range for the LiftPump. I did't like that at all. I can see the dollar flying when my injector pump fails while the normal 3psi is determined to be adiquat. Does this sound like Cummins has learned some tricks from Diamer Chrysler?
The good part of the this event was meeting JB Hale. He even clocked out to give me a little training about running voltage to the lift pump. What a guy.
