Supplemental electric fuel pump and regulator rec's

here's what i run
Walbro GSL392 Inline Fuel Pump 255LPH HIGH PRESSURE (universal external pump)

Good for 650 hp and darn near silent and you will need a bypass regulator i like aeromotive but holley has them also , and you will also need a return . I'm sure there are better setups but this is quiet and reliable .
