Just take it to the dealer, your covered under the 5 year 100K warranty. The pump has been revised several times the latest ends in AA suffix. Good luck

Forgot to mention... If your buying the lift pump, and installing it yourself, get it from a Cummins repair facility. Cost about $140-150. It's the same pump as the dealer has, but they will charge you almost double that amout for it...

I heard they are cheaper calling Cummins in AM THANKS for the info

Checked Cummins by me early last week (just in case dealer was going to be a butt head) they had 4 coming in, $168. 00. Get info off your engine data plate before you call they need serial number 8 numbers all numbers no letters.

They were between $140-$150 just a few weeks ago (Cummins NW)... Must be the "supply and demand" theory at its best...

Yeah I heard that - I was surprized myself, as I previously heard $148. 00. Probably should pick one up as a spare anyway going on X-Country trip again this summer - got 92,500 miles and dealer just put a new one on last week. Just hope if it goes bad it dosent take me the 2. 5 hours it did for the dealer's Tech to install one. :-laf
