Fuel System Description

Fuel System
The fuel delivery system consists of the fuel tank (1), fuel pump (2), fuel filter (3), fuel feed hose (4), fuel delivery pipe
(5) (including fuel injectors) and fuel pressure regulator (6). There is no fuel return hose. The fuel in the fuel tank (1) is
pumped up by the fuel pump (2) and pressurized fuel flows into the injector (8) installed in the fuel delivery pipe (5).
Fuel pressure is regulated by the fuel pressure regulator (6). As the fuel pressure applied to the fuel injector (8) (the
fuel pressure in the fuel delivery pipe) is always kept at absolute fuel pressure of 300 kPa (3.0 kgf/cm
is injected into the throttle body in conic dispersion when the injector (8) opens according to the injection signal from
the ECM.
The fuel relieved by the fuel pressure regulator (6) flows back to the fuel tank (1).
