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 injector.

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 injector during the
removal and installation procedure.
