IPVREX VP44 PUMP??
Has anybody seen or heard about this pump before? There is a sticker on it that says "IPVREX" on top of pump. Did a search....links to thoroughbred diesel....is this considered a hotrod pump, and if so, could it cause a stumble/misfire at idle, low rpms? Just bought this truck and really dont have much history on it.

That is there "High Output" pump.
Yes some pumps do cause the trucks to idle weird. |
thank for the info

IPVREX VP44 PUMP??
Is it like a lope sound?

Bacon......not lopey.....more like intermittent miss at idle. You can put truck in gear and let clutch out just enough to "load" the engine and it purrs purrfectly. ??? But...at idle it will "miss" until you run the rpm's up til say 1500 and then it will smooth out. This is of course after it has generated a little heat. Cold start = no miss. Hellifino' Just bugs the heck outta me....maybe vp electric voodoo box???

My truck is equipped with that same pump. Yes it a HO pump, but mine has been modified by thorough bred diesel making it a hot rod pump. If the truck has a lope at idle thats normal. thats the pump lope. Its just going about its job. mine has 150hp injectors and smoothes out bout 1600 rpm them starts again at 2000 rpm. :rocking:
