Fuel pump decision

Matts440 said

Hello, for those on race gas and pump, efi which would you rather run two pumps controlled separately second to come on at a set psi, or a single that will handle it All? For the two inline looking at AEM 400lph pumps or just go with a magna Fuel 625 or 525 series, looking for around 1000hp on pump and 1600hp on c12, the magna is only $100 more but less plumbing for sure. Thoughts???

Are you running 2 separate tanks, or mixing the two in one tank? Take a look at Fuel Labs pumps and talk to one of their tech's. They know more about proper plumbing and what works than most of us.

I run one of their smaller low pressure pumps for my six-pack carbs. It runs on low speed to feed the center one and kicks up to high speed when the outboards open. A simple NoS switch grounds when they crack open and shifts the pump into high speed.

Since you have EFI, depending on the ECM, you can use pulse width modulation to control the pumps. If it were me, I would check with the guy at Vaporworx too.
