How a fuel pump works - How a Car Works

A mechanical fuel pump is driven by the camshaft , or by a special shaft driven by the crankshaft . As the shaft turns, a cam passes under a pivoted lever and forces it up at one end. The other end of the lever, which is linked loosely to a rubber diaphragm forming the floor of a chaer in the pump, goes down and pulls the diaphragm with it.

How Does a Fuel Pump Work? | eHow UK
