Recommends Diesel Lift Pump
Lots to choice from AirDog, Fass. PPE, Fleece PowerFlo, Aermotive, etc; etc;.......right now using DRP Fass ( small upgrade from OEM faulty fuel pump) running on '01 3500 DRW Dodge Ram 5.9L 24V Cummins
Looking to install 100 - 150 gph lift pump.........I hear AirDog 2-4G is a newer more quiet running pump - Fass titanium seems to be comparable to the AirDog.........haven't researched the rest, but my 2nd gen
truck with mods to support the 400 hp range will need 100 to 150 gph lift pump ...........would like to know your recommends from "good or bad" in reliability, customer care & warranty.

I put an AirDog 150 gpm pump on my 2011 Duramax last summer as insurance after a CP4 failure. It is loud enough you hear the hum over the motor when running when standing outside, but quiet enough to not hear in the cab. The kit was fairly complete but seemed to be lacking half of the bracket hardware, was on a time crunch so little field fabricating made it work. Will revisit placement someday as I don't like how the filters hang so far below the frame rails for any off-road situations. Otherwise very complete and well put together kit. I will say night and day difference in throttle response versus no lift pump, drastically cut lag response when mash the throttle. Truck feels way stronger than before however, that may be more of a result of new CP4 pump and fresh reman injectors. Only bought the AirDog because Fass system was back-ordered at the time. Only other issue I had was vacuum sensor on fuel system started leaking fuel badly as the internal o-rings used to 200k miles of vacuum didn't like the new positive pressure of the system. Was easy sensor change though and no way has bearing on effectiveness of lift pump.
