Hello and thanks for donating


Do not confuse the electric fuel pump with the injection pump.

All Mercedes-Benz fuel injected engines are equipped with electric fuel pumps. The electric fuel pump is located underneath the rear floor panel. The fuel return line was also eliminated and a check ball installed in its place.

Two types of fuel pumps have been used. One, the large pump, has been replaced with a new small design which has a bypass system to prevent vapor lock.
