Engine/Transmission (1998.5 - 2002) ~~Poll~~ Vp44 Failure By Model Year ~~Poll~~

[DieselMinded]

I going to venture a guess and say the 2002 CTD has the highest failure rate bombed or not

Lets see how your poll matches up. Me thinks there was a batch of bad pumps in 2002, or they were cleaning the warehouse out. SNOKING

Thanks for the link !!! That Sucks ! ...



Is it fair to say that with each newer model year theres more on the road ?

2000 was a short run, like a half of a year. 2001/2001. 5 ran for 1. 5 years aprox. 2002 was a full model run, but people new the 2003 was going to be a 3rd gen, I do not know what effect that had on sales, may have increased it!!!!! SNOKING

My 2001 was delivered to me July 2000. So 2001 was easily 1. 5 years long.

Yeah - without knowing coresponding number of units reporting, it's impossible to compare failures per thousand units...



Sorta like comparing stock lift pump failures against aftermarket stuff like FASS and RASP - only 2 failures out of a possible 100 users makes the aftermarket units LOOK bulletproof, compared to 20 stock LP failures in 1000 users - but the failure rate per thousand is exactly the same...

How about doing another poll that asks: "What model year is your truck?"



It wouldnt be scientific, but may give more insight on the percentages of trucks that are 2002, etc.



Also, it would be helpful to know how many of the updated pumps are failing as compared to ones that came as original equipment.

Thats what this is

DM,

I think he meant "what year do you own?", not "what year have you lost a pump on?"

Opps OK ,,, Well that may work LOL

[Houser]

I think thats the same thing

I took it as the model year that had a pump failure. Failure was in 05 (53k). I think it takes long runs (not sure about summer / winter) at high rpms with stock fuel system, and some heat cycles (maybe measured in thousands).



Long runs because the stock fuel canister dumps return fuel back into fuel cannister = hot fuel,



High rpm because on the Vp44 rpms = heat generated



Heat cycles maybe measured in thousands becasue the heat effect seems to be cumulative



Not sure about summer / winter because

OEM fuel filter is one heat agent,

engine block is a heat agent,

underhood post shutdown temp is a heat agent

and on a long run the heat would be pretty much at operating temp (I think)

Let me try this again :-laf

I think shortshift was saying that we need two polls

#1 what model year do you own

#2 What model year have you lost a vp44 on



It wouldnt surprise me if '98. 5, '99, and '00 combined would only about equal '01 or 02 in production. '98 and '00 were both short years and I'm quite sure I've read that sales increased a lot through the 24v production run.

Need another list on this poll,,



If you do have an 01 or 02, No failures yet and what mileage so far?



I have an 01 made in 2000, I have 71 K on it and I pierced the wire. . Still running strong at around 400 Hp..... not bad huh?

My 2202 6speed went just went out at 60000 miles, going to dealership tuesday. I bought it with 20000 + miles. First thing I did was get a fuel pressure gauge all was well with fuel presure. The next thing I did was add 4100 carter pusher pump all was well. Lost 2 lift pumps after pusher install, most recent 58000. I thought I was doing all the right things and still my vp is dying, is the 2002 ho vp44 different and if so is that the reason of the high failure rate on the 2002

 

[FourBarR]

Dont have a failure yet. 98. 5 with 406,584kms on original pump.

 

[Gary - K7GLD]

For what it's worth, I've posted another poll for establishing the percentages of those on this board responding, as to how many of each year 24 valve trucks we have here - might help better understand varying numbers of various failures...

I think there is a basic design flaw in the 02 fuel system with respect to too high a general operating temperature and therefore the Vp44's are taking the hit.

I went thru 3 VP-44's & 6 Lift Pumps prior to installing the FAST Pump. I now have over 100,000 on my VP & Fast with nary a problem, except for twisting off the Input shaft in my transmission the other night.
