Fuel System
The fuel system consists of a fuel tank, a fuel pump, fuel lines, filter, and a line pressure regulator. Fuel is supplied to each injector at a constant pressure. Only fuel injection duration is varied, meeting changing engine requirements.
The fuel pump is an electrically operated vane pump. Fuel is strained through a mesh screen before entering fuel pump. There is a check valve on outlet side of pump to prevent fuel supply from draining back into tank.
The in-tank fuel pump assembly is comprised of a main fuel pump, a pressurized container and a fuel feed pump. See Fig 1 .
