Fuel Pumps & Lines

The fuel pump sends fuel to the carburetors. The quantity of fuel delivered is metered automatically in direct proportion to the amount of fuel dispensed by the carburetors.

The fuel pump consists of an upper and lower assembly. The upper assembly accommodates an inlet and outlet valve, and a fuel filter. The lower assembly contains the actuating plunger. Located between both assemblies is a diaphragm and diaphragm spring. The diaphragm is built up of several layers of a fuel-proof material, and is sandwiched between two supporting discs which are riveted to the plunger coupling; the diaphragm also acts as a gasket.
