Fuel System Description

Fuel system
The fuel delivery system consists of the fuel tank (1), fuel valve (2), fuel pump (3), fuel filter (4), fuel feed hoses (6) and
(7), fuel delivery pipe (8), fuel injector (9), fuel pressure regulator (11). The fuel is pumped up by the fuel pump and
pressurized fuel flows into the injector installed in the fuel delivery pipe. Fuel pressure is regulated by the fuel pressure
regulator in the fuel valve. As the fuel pressure applied to the fuel injector (the fuel pressure in the fuel delivery pipe) is
always kept at absolute fuel pressure of approx. 294 kPa (2.9 kgf/cm
2
, 41 psi), the fuel is injected into the throttle body
in conic dispersion when the injector opens according to the injection signal from the ECM.
The fuel relieved by the fuel pressure regulator flows back to the fuel tank.
