Hey guys im in need of a decent electric fuel pump. I have a 550HP 6.0 "carbed" LS engine. I am using a holley "red" pump right now as I just got the truck fired up and thats what I had laying around. I would maybe be running some nitrous in the future so I would have to keep that in mind as well. What can you guys recommend? Thanks fellas!

Use two Carter #P4594 pumps thru two 3/8" fuel lines.
use the Holley red for the nitrous thru its own line and pickup.

Thanks. Isnt two carter pumps a little overkill? Wouldnt an aeromotive pump or a mallory work too?

Here is some specs on Holley pumps

Holley Red 97 gph (frre flow) 67 gph@5 psi
Holley blue 110 gph(fre flow) 70 gph@9 psi
Holley black 140 gph (free flow)120 gph@9 psi
Hope this helps, I dont know how much fuel your motor will use, but,2 MTU 2000 hp each diesel engines pushing a 68 foot 40 ton boat use 120 gph at w.o.t.
So may be I think youll find somethin here that will work,providing perfect stoich. i dont think 550 hp plus a big shot of O2 will use any more than maybe 40 (just a guess).jimmy buffett wrote a song about this "Overkill"
Just kidding we all like HORSEPOWER!!!!
Im just waiting for the attack "there is no perfect stoich in a non computer motor" I already now a little entropy guys,honest.
Oh I almost forgot

No not at all. They (2) are cheaper than an areomotive or other......
With 2 if one happens to fail, you can get home on the other.
3/8" fuel lines, plumbing and filters are much cheaper to service.
No regulator is required.
If you need a replacement they are readily available locally.
The are very dependable and long lasting as a rule.
One of the few pumps actually designed for full time use.
