Abstract: A fuel regulator for controlling one or more carburetors and having a return to the fuel tank arrangement. The invention comprises a unique arrangement of an hourglass shaped plunger that permits virtually unrestircted flow through the body of the regulator from the inlet to the one or more ports which lead to the single or multiple carburetors. A method of operation wherein the return fuel flow is never completely shut off is provided during normal operation. This provides the advantages of reduced demands on the manufacture of the return line seat, and always permits at least some flow through the return line during the normal operation. Thus, a highly efficient, high volume, low pressure regulator for carburetted, high performance engines is provided.

Abstract: An add-on electric fuel pump having numerous advantageous features including an improved manner of replacing the seal at the shaft on the electric motor side of the pump, a versatile mounting bracket, and a fuel reservoir member having a plurality of chambers which permit internal bypassing of the fuel, thus avoiding a return line to the fuel tank. The fuel reservoir member is formed with a set of fuel chambers which cooperate with the pump to permit internal turbulent bypassing of the fuel, thus improving cooling and avoiding vapor lock.
