How a fuel pump works | How a Car Works

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 chamber in the pump, goes down and pulls the diaphragm with it. When the lever pulls the diaphragm down, it creates .
