Long story short... Lift pump is headed south, the Dealer say's the flow is within spec Is there someplace online that I can purchase a lift pump? Also has anyone found out for sure if Dodge will still honor the warranty on the injection pump if you go with the RASP???

 

what is your pressure readings?

 

I am getting between 11-12 at idle, under full throttle I can pull it down to 2 and running down the highway it's about 10. I just changed the fuel filter not quite 5k ago, and I know the guage is correct because I have another small fp guage under the hood inline right before the sending unit for the in-cab guage.

 

Look for a Cummins store. Maybe they will send you one if they are to far away.

 

i run 12 to 13 at idle and at the most i can pull it down to 7 psi wide open. i also run in the 11 -12 at cruise speeds light throttle. i also passed the volume test. you might try a filter. i am reading mine pre filter . a filter would be a easy and cheap fix.

 

you might go here and contact a dealer. some have web sites that you can purchase parts.
