Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel System
The fuel system consists of the fuel tank, a fuel feed pump, fuel lines, in-line fuel pump, filter, and a line pressure regulator. See Fig 1 .
Fuel is supplied to the injection system at a constant pressure and volume. Only the injection duration needs to be varied to meet changing engine requirements.
The fuel feed pump is an electrically operated vane pump. The pump is located near the bottom of the fuel tank. Fuel is strained through a mesh screen before entering the fuel pump. There is a check valve on the outlet side of the fuel feed pump. This prevents the fuel supply line from draining back into the tank.
The main fuel pump and filter are attached to a bracket located underneath the vehicle, under the left rear seat. The main fuel pump is an electrically operated roller pump. The pump is equipped with a check valve to prevent back flow. The pump also has an overpressure relief valve which opens if the fuel system becomes clogged and the pressure rises too high.
