Weldon 19311-A Sportsman Fuel Pump

Weldon debuts the Sportsman Fuel Pump: their first hand-adjustable pump/bypass combination�lifetime warranty included Cleveland, Ohio: Weldon, the only racing fuel pump maker who uses all-metallic internal pumping components�no plastics or Phenolics permitted�has announced a new and innovative fuel pump with an integral bypassing regulator. Called the Sportsman, it is petite, light weight and supports race engines producing up to 1200 horsepower. Because its internals are made entirely of tool steel, including the pump ring, pump rotor, and pump vanes, the Sportsman�s inner working parts will neither fracture nor deteriorate with heat nor will its flow be impaired when fuel pressure is increased. Operating on 12 to 16 volts this 4.1lb fuel pump has impressive pumping power with surprisingly low amperage draw. Efficiencies in the pumping chamber have a decisive effect on reduced amp draw. Featuring AN-10 inlet and outlet ports and AN-8 bypassing port (all ports chamfered and counter bored for O-ring seals) the Sportsman boasts a Teflon diaphragm with a 1.7 sq. in. surface area. This diaphragm effectively reduces fuel pressure fluctuations and is compatible with all fuels.
