(3) Fuel Feed System
Fuel pump 3 (low pressure mechanical type) draws fuel from fuel tank, and feed it to fuel feed pump 5 (FFP) located in
the vapor separator 4 through fuel connector 1 and fuel filter 2.
Highly pressurized fuel, fed into fuel rail 7 and fuel injector, and then, injected into intake manifold.
Excessive fuel that is not used by fuel injector passes through fuel regulator 6, and circulated in the vapor separator 4
to keep fuel pressure constant.
Stabilization of fuel pressure is performed by fuel regulator that is built into the vapor separator.
