What is a good lift pump for a 2001 Duramax LB7 and is it worth it if I only want to make 400 to 500 hp.

 

There are 2 that I can think of right off the top of my head, Airdog and FASS.

 

Like kit or plumb in yourself? I plumbed in a 10 psi walbro FRB-5 followed by a high eff filter base from napa and it works great. I spent less than $140. My max tune is between 400-500hp.

Also it is so much quieter than a fass or airdog. You can hear it clicking when parked at idle but my engine drowns it out when I take off.

It is a flow through design as well in case it ever does fail it won't leave you stranded.

A down side is that it is 1/4 npt, but I used stainless fittings and drilled them out to the same size as the heavy wall tubing I plumbed it in with. IMO it shouldn't matter while the pump is working. It is capable of flowing 60 GPH.

 

the airdog 165 is a easy install, but a pusher pump like a raptor or the small fass works quite well.
