Avoiding Fuel Starvation in the BMW E36 M3 via the Installation of Twin Fuel Pumps
Under racing conditions, the engine in the BMW E36 M3 may “starve” for fuel when the amount of gasoline in its tanks falls below a certain level. This Application Guide details the installation of twin fuel pumps on a 1995 M3 Lightweight to alleviate this problem. The E36 3 series1 uses a molded one-piece plastic fuel tank under the rear passenger seats. A small passage over the driveshaft connects the two tank halves.
Fuel is added through the filler pipe. Fuel is extracted from the right-hand-side2 (rhs) of the fuel tank via an in-tank fuel pump. The fuel passes through a filter and pressurizes the fuel rail, to which the injectors are attached.
