Holley Fuel Pump Question
« on: June 26, 2013 - 03:04:58 AM »
Says below the pump has a fuel pump pre-set shutoff pressure from 6.5 to 8psi.

Does that mean each pump will not discharge above a certain pressure? Wonder how you know
where it is set at?

once it reaches the pressure limit the bypass valve opens & recirculates the fuel
