Abstract: Fuel bowls are placed on opposite sides of a carburetor, and a fuel transfer tube extends between the fuel bowls. External fuel receiving fixtures are mounted in fluid communication with the fuel bowls and have nipples facing each other. The fuel transfer tube is telescopically mounted at its ends to the nipples and O-rings seal the ends of the tubes to the nipples.

Abstract: Fuel pump 10 includes a filter 42 that rests on ledge 48, between the pump housing 12 and inlet cap 56. Filter detector 50 has a valve engager stem 62 for opening the check valve 58 and bearing feet 52 that engage the perimeter of the filter but the bearing feet are out of alignment with the ledge. When the filter is absent from the pump, the bearing feet 52 of the valve engager move beyond the ledge 48 and the valve engager stem 62 retracts from the check valve 58 and the valve closes to terminate flow of fuel to the pump, thus limiting the fuel that can escape from then pump when it is opened. At least one of the inlet and outlet caps 56 and 76 are rotatably mounted to the intermediate body of the pump to allow the fuel inlet and outlet to be oriented at angular intervals about the pump to facilitate the connection of fuel lines to the pump.

Abstract: Cooling fins 72, 74 and 76 extend about the fuel pump 24, perpendicular to the longitudinal axis of the fuel pump and parallel to the anticipated direction of flow of the air stream generated by the movement of the vehicle. The cooling fins are formed on the pump bowl 36, hood 34, and mounting arm 49 to extract the heat of conduction transferred from the engine block 12 to the mounting arm 49 and heat of radiation and convection transferred from the engine block and its accessories to the pump bowl 36, hood 34 and mounting arm 49.

Abstract: The fuel filter housing (12) is formed of inlet segment (14) and outlet segment (16) that are telescopically mounted to each other, with a seal (44) positioned between the mounting flanges (38) and (40). Valve (60) is maintained displaced from its valve seat (58) by valve actuator (66), by the valve actuator engaging the perimeter of the filter (34). When the outlet housing segment (16) moves away from inlet housing segment (14), the filter and the valve actuator (66) also move, allowing the valve the close. The amplitude of movement of the valve (60) toward and away from its seat (58) is smaller than the sealed telescopic movement of the housing segments, so that the valve closes before the segments separate, thereby limiting the amount of fuel lost from the fuel filter assembly.

Abstract: Fuel accumulator (10) includes a segmented housing (12) that includes a front wall (34), rear wall (36), and a fuel delivery ring (38). The fuel outlet ports (40) and (42) are formed in the fuel delivery ring, and the fuel delivery ring can be detached, rotated and reattached at different angles about the housing. Flexible diaphragm (72) and the air behind it in the rear wall interior cavity (50) modulate the pressure of the fuel inside the fuel accumulation chamber (60), (70), as the fuel passes through the filter (76).

Abstract: Water fill neck (16) is mounted on the intake manifold (14) of an internal combustion engine. The manifold includes an upstanding collar (22) that surrounds the lower support platform (57) of mounting body (55) of the water fill neck, and liquid accumulation spaces (50-53) are formed within collar (22) and about the lower support platform (57) of the water fill neck. The overflow from the water fill opening (18) past the gasket (37) will be retained beneath the outward projecting rim (60) of the water fill neck, thereby reducing the likelihood of liquid overflow onto the surfaces of the engine.
