Fuel System Description

CAUTION
!
This engine requires the unleaded fuel only.
The leaded and/or low lead fuel can result in
engine damage and reduce the effectiveness
of the emission control system.
The main components of the fuel system are fuel tank,
fuel pump assembly (with fuel filter, fuel level gauge, fuel
pressure regulator), fuel feed line and fuel vapor line.
For the details of fuel flow, refer to "Fuel Delivery System
Diagram".

Fuel Delivery System Description

The fuel delivery system consists of the fuel tank, fuel
pump assembly (with built-in fuel filter and fuel pressure
regulator), delivery pipe, injectors and fuel feed line.
The fuel in the fuel tank is pumped up by the fuel pump,
sent into delivery pipe and injected by the injectors.
As the fuel pump assembly is equipped with built-in fuel
filter and fuel pressure regulator, the fuel is filtered and
its pressure is regulated before being sent to the feed
pipe.
The excess fuel at fuel pressure regulation process is
returned back into the fuel tank.
Also, fuel vapor generated in fuel tank is led through the
fuel vapor line into the EVAP canister.
For system diagram, refer to "Fuel Delivery System
Diagram".
