To repeat:

Yes I lost a '99 vp44 but I did have 221,000 on it. I also had completely stock fuel lines and pump with rv275 injectors. I rarely put any conditioner in it. I had been through three lift pumps and ran 170,000 or more with no gages. All heavy pulling.

I recently rolled 250,000 miles and still on the original VP.

hauliday

both times i replaced my pump was due to bad fuel Water and i was told when they check the pump and they find water they will not warranty it at that iss what i was told by the place where i got my replacement from m&d dist. in houston

I think I would replace the filter assy pronto. Either that or go to a FASS or Preporator.

205,000 with oringinal vp and just replaced the oringinal lp because it would drop under 5psi wot and took too long to prime after filter change. My truck was bombed at 100k with injectors and comp. At 150k the trans was replace with DTT, the tc was slipping, the rest of the trans was still good for the miles. Only used additives a couple times,Power Service brand. My truck has been very dependable. Just got back from a 6000 mile round trip to CA and back.

I voted on behalf of my friend, who is not a member of the forum. I hope that doesn't screw up the results.

He HAD an '01 that failed 3 times in under 100k. He got so mad he traded it in on.............. a new Duramax. Egads!?!!??!?!!?!?

Ok the list in order:
Carter pusher + stock LP =19psi @40k>
Comp less wire 92k>
Jammer IIs 95k>
Wire pierced 109,235
New pump 109,239

Maybe you could run a control group too. Same four question without failures. That may be benficical to the study.

I have got Geno's Bangos but never have taken the time to install them and fuel guage from Andy.. I hate changing the fuel filters, the fear factor of failed lift pump. Change lthe filter ast weekend and forgot to bump the starter, I filled the fuel filter with clean diesel thank god, short story, it startd and die imedately, then would start, so I bump the switch about six ccyle. nothing. engine dead, ??? then crank the engine several more times. I was ready to change the Lift pump then caught hold and all is well.

Thanks to GOD.

Cheers

JBlock,
Really the way I have it set up, those who have not had failures are in essence the control group. Statistical Analysis, at least the way I will present it with the data given, will end up being more of a failure rate per (X) trucks with an accompanying confidence level (expressed in terms of percentage) for that failure rate.

A control group scenario would look like 10 trucks with ONE of the mods and 10 trucks STOCK.

Test for an arbitrary 50k or something and see what failed at an increased rate.

See the difference?

Thanks for the suggestion though. Scott
