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.What causes these pumps to fail?
Dealers may or may not, certainly not under warranty.Will the dealership do that or will I have to tow my truck to another garage?
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.If so, who does that kind of work?
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.All pumps make a better pusher than a puller. 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.
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.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.
