HP Series Regulators
What size return line should be used ? I have a Holley Blue Top pump with 1/2 inch supply line, 425 HP single 750 cfm Holley carb. 5 gal. fuel cell in a footbrake bracket car.
Bought model 510-12-841 that's for low pressure/carb ... can the spring be replaced and use for high pressure FI fuel pump? I am switching to FI and hate to spend another $100 on another one.
Will this work with the Holley Mighty Mite fuel pumps
