Fuel pump
I'm running a walboro 255 but its max psi 60. Should I upgrade? Or is that going to be enough pressure?

Re: Fuel pump
Walboro 255 will be plenty of pump! It's actually a popular upgrade in all LS powered cars. Should supply plenty of fuel for up to about 500-600 hp N/A! Many LS turbo trucks run these.

Re: Fuel pump
Are you thinking that I should probably buy a different pump? Also what PSI should I be looking for at my fuel rail?

Re: Fuel pump
Well you didn't really tell me what your running, but if its under 425-450, you'll be fine. If you are seeing more than that, or running a turbo, nitrous etc...then I'd say you'd want to consider something bigger.
Its about 58psi at the rails.

Re: Fuel pump
Check out my build thread. I'm running the Holley Fuel Pump and FPR. It's good for 900HP iirc
