Engine/Transmission (1998.5 - 2002) replaced lift pump 99 2500

After searching the posts and getting some great info I changed out my lift pump today. I decided to get to it this morning before my kids woke up and decided to help. I love my 2 year old and a 5 year old but being this is my first time changing the lift pump and after having a hard time getting the truck to start after a fuel filter change . I was a little nervous with changing the lift pump.



I figured that my old pump was on the way out because I was getting 10psi at idle and around 7-8 at cruising and below 4 at wot . From what I have learned from this site that seemed a little low to me . But the clincher was watching the pressure fluctuate from 10 psi to 5 psi while driving to work. .



I ordered the pump from a local auto parts store and got the carter pump at $ 265 ( Canadian funds). The dealer wanted almost $500 .



Here is the procedure I used, much the same as what has already been posted. Did it all from the top , took 1. 5 hours . Should go faster next time, hopefully not for a while though.



1. Disconnected -terminals on both batteries

2. Disconnected quick connect fuel supply line . ( I was worried that fuel would drain out of line but nothing came out , had a full tank too) I also put a plastic bag over the starter.

3. took off bolt for fuel supply bracket .

4. took off banjo bolt for inlet on filter.

5. took off 3 nuts on top of lift pump bracket to engine

6. threaded pump up through every thing that was in the way and then removed electrical line at bottom of pump.



7. old pump out , put fuel lines from old pump onto new pump, put on new banjo washers . ( had to use 6 new washers, for the supply line to pump, outlet line from pump ,and inlet line to filter). only put banjo bolts on finger tight for now.



8. weaved new pump back down put on three nuts for pump to engine bracket , then connected fuel supply and its bracket , then attached inlet line to filter. Finally connected electrical and tightened everything up to

specified torques. ( I could only get my torque wrench on one bolt so everything else was guess work, 18 ft/lbs doesn't take much though)



9. primed system by cracking supply line to injector pump . Started right up with one small hiccup.



Pressure is now 15 psi at idle, Have to take for a test drive later to see what it does while driving.



Thanks to all the posts I read to get this done, this site is awesome.

Good job. Would be nice if the manuals were that easy to understand. On the re-install they usually say something like "reverse of removal". Welcome aboard. bg

hello them lift pump seem to go out quite a bit i am on my second one, i didn't know auto parts stores had those pumps? But i do know if you go through a freightliner dealer or probally and semi dealer they have them even cheaper straight from cummins as opposed to going to a dodge dealer. I have a led light on my dash that warns me when the transfer pump falls below a certain PSI but i think a fuel gauge would be nicer are they much of a pain to install? thanks chad

Thanks for the great post. I've printed it and its going into the shop manual.



Could you post the brand and part number of the pump you ended up using?



Thanks,

I recently bought a spare lift pump with harness for a trip to Arizona. It cost $179 at Cummins-NW in Anchorage. While on the trip I had problems and the DC dealer in Oregon replaced my lift pump with the new in-tank model. Now I have no use for the spare. The in-tank model puts out more volume at lower psi. but runs cool and should last a lot longer... ... . I hope.
