expected life of VP44
Can anyone tell me what the expected life of the VP44 is? (assuming that it is never affected by a bad lift pump) Or is there really no expected life info...

I think the "official" expected life expectancy is 100,000 miles.

Mine was dead when they went to take the truck off of the rail car in Santa Rosa, NM. The dealer had to have a tow truck drive 4 hours each way to get the truck and then had to replace the pump before I could take delivery. This was after ordering the truck in July of '99 and the truck not being built until November.

IMO, even if the pump is suppose to last 100,000 miles, that isn't all that great... I have a 99 and the concerns about my 53 block, lift pump woes, and the cost of replacing the injection pump should the need arise, I'm really starting to wish that I had a 12 valve....

i believe the pumps got better in 2001 and 2002 models. with all the failed ones a mans a fool for not investing in a fuel pressure gauge. a lot of injection pumps have been replace when they were not at fault. and a lot have been replaced due to lift pumps going bad causing the injection pump to fail. the way i see it is that a fuel pressure gauge or low pressure light is a must have item. also frequent filter changes and watching the quality of fuel you use are very important. i have to laugh at the guys that post almost bragging that they have 70,000 plus miles and never serviced the fuel filter. one other item that does not help is the lines that can develop leaks and put air in the system. that shortens pump life also. again a gauge would give you warning the troubles are starting some where.

I got to 150,033 on the clock till another (one of 5) lift pump quit and got her done. I put a FP gauge and an aircraft fuel pump on 59000 miles ago and never have had another problem...

Lift pump and injection pump??
Would someone please explain what is and where in the fuel line the lift pump and injection pump are? I'm have guages including a pressure guage installed, but what do you look for when one of these pumps begin to fail? Can you drive on til the rig stops or do you pull over to save the other pump? Thanks

I was going to purchase a 2002 this coming Friday. I drove it, and felt like it was under powered. After thinking it over, and advice from this forum, I asked him to take it to a reputable diesel shop. He took it to a shop in Texas and they told him that of course it needs both pumps. The truck has 150,300 miles on it. I agreed to still buy the truck after the repairs are done, but he thinks that I should pay for the repair.

Jay,
The lift pump is on the lower rear portion of the drivers side of the engine. It sucks fuel from the tank and feeds the injection pump. The injection pump is on the upper front of the drivers side of the engine and pressurizes and sends fuel to the injectors in the cylinder head.
Once you get your fuel pressure gauge installed you will have an idea on the health of the lift pump. You probably don't want less than 10 psi at WOT under load. If you ever see less than 8 psi you have problems.
For the injection pump, there are several symptoms from the PCM throwing a code (P0216 I think), to divability and smoke issues.
Do a search and you will find more information than you have time to read.

I agree w/you cummins2, I am on the look out for a 98 12v quadcab. I gotta have the quad cab for the kids and the wife. I have not had any problems w/ my VP, but have replace 2 carter, and 4 Holleys. Hopefully the FASS pump will last as long as they warranty it for.

I agree with herb:
Tell him you will pay to have the truck fixed and have him lower the price the $1800. That way you know its fixed right and you get the warrenty
