Ideal for carbureted power plants not using a separate fuel pressure regulator, the high output (H/O) Fuel Pump is designed for engines making 200-600 HP and is ideal for street cars and mild race cars alike. Similar to our SS Fuel Pump design, but internally regulated to 7 PSI. Available with optional 3/8' NPT (or) ORB -8 inlet and outlet ports. Durable billet construction. Fuel flow exceeds 90 GPH at 5 PSI and draws less than 5 amps. Internally regulated to 7 PSI, eliminating the need for a separate regulator on most carburetors. Rated for continuous duty, the pumping mechanism features a composite rotor, stainless steel vanes and heat treated steel top and bottom plates for durability.
