Fuel System
Fuel injectors, controlled by the ECM, are
installed in the fuel rails on each side of the
intake manifold. A cross-over pipe connects the
two fuel rails together at the front of the
manifold. A test valve in the cross-over pipe
allows the fuel rail to be pressurised and
depressurised during servicing and
troubleshooting.
A pressure regulator on the rear of the right fuel
rail controls the pressure in the fuel rails.
A return line directs excess fuel from the
pressure regulator back to the fuel tank.
