Fuel pumped up by the fuel pump, flows through the fuel filter and is distributed to each injector
at a set pressure maintained by the fuel pressure regulator.
The fuel pressure regulator adjusts the pressure of the fuel from the fuel line (high pressure side)
to a pressure 250 kPa (2.55 kgf/cm’, 36 psi) higher than the pressure inside the intake manifold
and excess fuel is returned to the fuel tank through the return pipe.
Fuel is injected into the intake manifold according to signals from the ECU.
