Large lift pump suggestions?

In what regard, fuel flow? All of the big name pumps flow close to what they claim. I believe Power Driven diesel did a few tests on lift pumps in regards to claimed flow/pressure.
IMO nothing can touch Fuelab in terms of big power flow-rate. For example, my Prodigy was hand tested and flowed with mineral oil before it left their company and that test sheet was included. My Prodigy is rated at 200gph @ 20psi. My actual pump flows ~225gph @ 10psi and closer to 235-240gph at 0psi.
AD/FASS claiming they remove air from the fuel is a gimmick IMO simply because gerotor pumps introduce turbulence into the fuel flow where as vane pumps (like the Fuelab) do not. The other benefits you gain from something like a Fuelab is the ability to run at a reduced speed when not in use reducing noise and increasing the lifespan of the pump.
I am looking into getting a lift pump, Is FASS no bueno?
Correct
I don't know if I'd go that far.
I like FASS in regards to 99% of guys. If you're going for big power I am not a fan of them. The last 165gph titanium signature I installed with a sump on a customer's truck honestly impressed me how quiet it was but that also was a bone stock LB7 that came in for exhaust/lift pump/tune/gauges.
Hate the way fass mounts. Are still loud compared toairdog. Customer service sucks. Tried a fass 260 on my race truck. Dropped to 0 psi just staging.
My fass165 with sump is very quiet. My old 150 and sump was super loud. I did have a motor fail within 6 months on the 165 though. They replaced it but was a hassle. I would definitely look into something else if I were to start over
What about twin Kennedy pumps ? I think John has a 1000 hp, dual CP3 truck running his twins with no fueling issues.
Both prodigy fuelab pumps I have self prime
