FUEL DELIVERY SYSTEM
The fuel delivery system consists of the fuel tank, fuel
pump, fuel filter, fuel pressure regulator, delivery pipe
and fuel injectors.
The fuel in the fuel tank is pumped up by the fuel pump,
filtered by the fuel filter and fed under pressure to each
injector through the delivery pipe. As the fuel pressure
applied to the injector (the fuel pressure in the fuel feed
line) is always kept a certain amount higher than the
pressure in the intake manifold by the fuel pressure
regulator, the fuel is injected into the intake port of the
cylinder head when the injector opens according to
the injection signal from ECM (PCM).

The fuel relieved by the fuel pressure regulator returns
through the fuel return line to the fuel tank.
Also for 4WD vehicle, sub fuel pump pumps fuel from
right side of fuel tank to left side of fuel tank (main
pump side).
For the structure and operation of the fuel tank and fil-
ter, refer to "ENGINE FUEL" in Section 6C.
