Just changed out my lift pump at 53,000 miles. Fuel pressure
has slowly been dropping from 13 psi @ idle to 11 psi @ idle
over the last six weeks. Bought the new pump from Cummins West
in West Sacramento , for $161.50 . Build date on the pump box
was Feb. 11 2005. Now I have 16.5 psi @ idle with a completely
stock fuel system. Pump is also alot quieter than the old one. Hope
it lasts longer than the original.

 

I just changed mine last week. My truck has 39k on it
Pretty easy to replace really- Thinking the FASS 2 is next though.

 

I am looking at the Fass2 also as it costs about the same as 2 lift pumps.
