Holley 12-427 32 GPH Mighty Mite Electric Fuel Pump, 4-7 PSI

Flows a good 4 psi works great for my 318 magnum carb swap with a 2 barrel 500cfm Holley

Bought to replace the same unit on my c10 carb truck and it fired right up first try. I don’t have any other pressure sensors, guages or devices in the system to regulate pressure. Just the pump and supplied filter

looks good havent used it

primes the carb after car has been sitting a few days or weeks , car start every time , no more waiting for the mach pump to prime the carb I only use this when starting the car . that or when racing to make sure there is no loss of fuel pressure with mech pump . if you have an older non fuel injected car this helps with reliability , car starts every time , don't need to crank the engine to get fuel to the carb . worth the money . Also easy to instal in cramped quarters can fit almost anywhere

Compact and easy to install. Brought my Foxbody mustang back to life.
