    Give your engine the extra fuel it needs with one of these MagnaFuel ProStar 500 Fuel Pumps. These CNC'd aluminum bodied pumps feature a high-quality low amperage motor that is designed to work with 12 V or 16 V applications.

    If my car makes 750 hp and I plan to add a fogger kit that has 400hp and a plate kit that has 200hp will this pump support my needs and does it have a return to the tank

    This pump will support your fuel demands and use a return line.
