Tomorrow, I'll find out why my 02' stopped and will not restart. As I mentioned in an earlier post, I just replaced the in-tank lift pump back in August 2007 and it had been installed less than a year before. What causes these pumps to fail?

All pumps make a better pusher than a puller. They mount the little sucker on the Block of the engine, And make them Strain all day long to suck the fuel from the tank to the engine. and the more mods you have the more fuel it will be demanding. The pumps dont like to be sucking fuel from all the way back there at a high rate. I HAve a pusher pump on the frame of my truck pushing the fuel to the Liftpump on the Block. PSI is good and hasent failed me yet.

But, if the pump is mounted in the fuel tank, isn't it "pushing" fuel to the injection pump?

I dont know about the intank pumps on these trucks but on gassers they are pretty crappy little pumps...I would say the motor is similar in size to a remote control car motor...very small.

Get a aftermarket pump (Airdog or FASS etc.) they cost more but sure beats dropping the tank all the time...

What does it cost to get one of those aftermarkets and install it? Will the dealership do that or will I have to tow my truck to another garage? If so, who does that kind of work?

Anywhere from 300 to 700 depending on brand and options. You can install it yourself. I'm not sure the dealer would install and aftermarket pump for you, but it doesn't hurt to ask.

I have been following a thread on TDR for some time now about this and the VP44 injection pump. There are a lot of thoughts on why they might fail. Ambient air temperature & not enough fuel in the tank are prime suspects.

IMO it was a poor design followed by a not so cool fix. Hey, that might even have been a pun.

Dealers may or may not, certainly not under warranty.

If so, who does that kind of work?
Depends on where you are. I know of several up and down the West coast, DDP in Monroe WA, Source Auto in the PDX area, Ponci's diesel in the northern komifornia on the coast, and many others who I can't remember just now.

they fail b/c Carter cannot make a reliable fuel pump. My bud at the garage does 3 or 4 gasser pumps a month due to quality issues.

I`m pretty green on diesel mechanicals. My `97 Cummins was rock solid reliable and my `06 is still going strong at only 39,000 miles. Gotta ask about this statement. If the long pull from the tank is so tough on the lift pump and the pusher you have back by the tank is so beneficial, why don`t more people do that instead of paying the long green for a FASS or Airdog system? Sure sounds like the hot (cool?) settup to me.

In gas apps i have had carter, aeromotive, holley, and a handful of autozone no-name pumps fail on me. On the cummins i still have the factory style lift pump and it is getting weak. I am seriously considering the walbro pump mod simply because i used one in a EFI camaro and years later it is still going strong, just very noisy intank.

I agree. I custom built my Walbro setup before there were any kits out. There were about 10 of us in the beginning. Now, I believe it was one of the best investments I've made in my truck to date. Since then, the Glacier Walbro kit has become very popular and is still pretty reasonably priced considering all that's available. In any case, the best thing you can do is go to an aftermarket system and be done with the fuel problem that plagues the 2nd gens. Hope this helps.
