1 - Electric Fuel Pump Assembly

5 - Fuel Rail Injector Assembly
When engine operates properly, electric fuel pump assembly (1) sucks fuel from fuel tank and filters it through
fuel filter assembly (3), and then deliveries it to inlet and return pipe assembly (4). Some fuel enters fuel rail
(5) and is supplied to injector. Some fuel flows back to electric fuel pump assembly pressure regulator (2)
directly. When fuel supply system pressure is high, diaphragm spring in the regulator is jacked up by pressure,
then valve opens and fuel flows out from the regulator. When pressure reaches normal value, the regulator
shuts off and fuel stops flowing out. Finally, system pressure reaches a steady state.
