Fuel Pump: Description and Operation

Components










The fuel system consists of many tiny holes and spaces that allow the movement of fuel from one place to another. These holes and spaces are milled to extremely high precision. This is especially true of the fuel injectors.

The fuel injector is very sensitive to foreign material. Foreign material will result in fuel system breakdown. Exercise great care not to allow the entry of foreign material into the fuel system or fuel injectors during the removal and installation procedure.

Important:
The Fuel supply pump must be timed to the engine and adjustment value must be learned to the ECM.
