Yeah that stuff can be expensive.

Based on BSFC needs you want 8-9 gph per 100 hp at whatever boost you are operating at. The free flow of the Carter is 50 gph but I wonder what it will do at elevated pressures?

I like the pumps and regulators that Aeromotive and Barry Grant make. But they are pricey. I settled on a Holley Black pump (14 psi and 140 gph) and an Aeromotive regulator for my non-boosted application.

I'm also using a fuel pump relay from Painless, parallel fuel feeds and brass filters before the pump and an Aeromotive canister filter after the pump.
