Mine's on pump #2 in 102k mi. I think however, i'm about to be on #3. After reading the diagnostic page on Chip's website i think it's inevitable

Replaced the VP44 on the '02 at 65k, had aftermarket lift pump since nearly new and it had never seen less than 12PSI. Also replaced the VP44 on the '01 at 105k, not because it was dead, but because I wanted an SO pump. Funny thing is the truck had a dead lift pump when I purchased it at 80k, but it just kept on going... Luck of the draw I guess...

OE VP44 - 246,911 mi as of two minutes ago...

 

[Bob Cochran]

130,000+ and have not replaced yet. I have a miss under load though but think it is the Adrenaline, I was hoping the last update that was supposed to fix it would.

 

[Dodoro]

The first VP was replaced at 80,000mi ( LP failed ).

The second one at about 175,000 ( VP started leaking from main body )

That's when I finally put an aftermarket LP and fuel pressure gauge on.

Stock VP

I have two trucks.

My 01 needed a pump @ 105k miles. My 99 is still runnning original with only 300k on it. Knock on wood.

 

[SAronson]

285K... . still original, but I sure have replaced a lot of other things!

I had my vp-44 replaced almost 3 years ago. Ran into dead pedal at hywy speeds. At the time I did not have a f press gauge. The 44 was replaced under warranty as the truck at the time had approx 35,000 miles on it. Up to this time I had been running a BD Plug n Power since the truck was new. At the time the vp was replaced, as preventative maintenance I installed a fuel guage (mechanical type) in the truck and replaced the transfer pump on the block with a Walbro fuel pump frame mounted, and a Vulcan line from the fuel filter housing to the vp. Sold the BD shortly after and have been running a Smarty full time since on power #7. Today the Walbro is running 14-17 psi depending on how hot it is outside. The fuel seems to thin out due to hot temps in the summer when it gets above 85-90 outside, and then runs approx 14-15 psi after hot restart. During acceleration the amount of throttle makes little change in the psi readings in the gauge regardless of temperature. See Photos Here.

Vp's can fail with a good lift pump, but they cannot survive with a bad lift pump!!!

I changed out the failure of a lift pump several times with the stock VP. Then built my own lift pump. I should have simply bought a Air Dog or Fass. Then bought a Blue Chip and it is been great.

I've never replaced mine on my 99 in over 240k miles. What may be surprising is that i've never installed a pressure guage. I also still run the stock style lift pump. What I do is I check the pressure at the filter every 7500 miles. I replaced the stock lift pump at 100000 with one that came from Cummins South. It ran good ( and was still holding 15 psi when I took it off), but replaced it with the FASS DDRP because I want to go to RV injectors and this pump bumps the pressure up 2-3 psi.

 

[hammersley]

Yep - tapped and had it done at 240,000

now at 311,000... ... running like a champ -AND with a 53 BLOCK.....

orig vp @ 182k



(knocks on head for luck)

Ive owned the truck for 5 years. I bought it stock and then Bomb'd it. Ive never replaced the VP and as far as I know its original. I never run less than 6 psi to the pump since Ive bought it. So far so good. With the mods (box on 2x3 in summer--- 4x5 winter) I have I get 17 MPG pretty consistently. Not bad considering I have a heavy right foot.

God bless,

chris

Replaced mine not too long ago clock was reading around 170k or so, presently 179.

Interesting with all the fearmongering that has gone on over the years about the dreaded VP44, mostly by brand F&C folks, that of the nearly 65% who have changed a pump only ~13% have had a repeat offender. I realize this isn't exactly scientific but I find it odd that with the reputation of the VP44 ~34% haven't changed the original parts 7 years after the last of the bunch was made. Kind of makes me wonder how many of the early ones 98. 5-2000 are running around on what those brand F&Cs fans would call borrowed time. :-laf

I honestly thought I was part of a smaller % who hadn't touched the pump.

Our '99 CTD is still running the original at 200,000 miles. Purchased new, a lift pump pressure guage was installed when the first lp failed.



The '01 vp was replaced at around 165,000 miles. Purchased used, with 77,000 miles on the odo, there was no history on the truck, but suspect that a past lp failure might have been the cause of the vp failure. This truck just rolled 200,000 miles on the odo.

I had to replace mine when the truck only had 31,000 miles. I got the P0216, dead pedal, and some surging. This all happened on one trip coming back from Oregon. The truck made it home towing the 5ver with no problems. This truck has always had stanadyne fuel additive in every tank and I had an AIRDOG on it before it failed and it never saw less than 13 psi. of fuel pressure. The truck still ran fine except for the dead pedal a couple times and the CEL light on. I didn't mess around waiting for it to die so I changed out the VP44 with an exchange unit from Diamond Diesel in West Sac. I asked them first to rebuild my pump and they said there we too many updates to be done on my pump and it would of cost me $1400 to rebuild mine. I bought one of their exchanges off the shelf for $1093. I asked how the current pumps were doing and they said the current pumps with updated: electronics, diaphram, main pump shaft & bearing, and the steel advance piston sleeve, were doing good with very few failures. I asked them to let me know what caused the failure in mine and a couple weeks later, after their main rebuild facility in Hayward tore the pump down, they found that the brass advance piston sleeve that was used in that vintage pump, was badly worn and causing my problems.
