Lift pump revision
Cummins just came out with a revision for lift pumps 3 days ago , here is the new specs , no air of course , no more than 6 in. of restrictions , now the fuel flow has changed to one cycle must deliver 1.4 quarts min. one cycle equals a bump of the starter and will give you apprx. 25 seconds of liftpump operation. do not turn key off till lift pump stops . and here the big one , under load , lift pump press. mins. is now 2 p.s.i. , Confusing eh.

Hey Guys, I've been busy for about a year since last time here. Lift pumps are still the talk of the day?
I just sold my 02, and picked up an 04 3500DRW HO/6speed.
And love it so far . To save me hours of reading, what do I have coming to me?
The 65~70 mph vibration I have.
