FUEL VAPOR SEPARATOR
The fuel vapor separator incorporates a float system that maintains a constant fuel level inside the separator
chamber.
As the fuel level decreases, fuel flows into the vapor separator from the low pressure fuel pump.
The function of this unit is to separate vapors from fuel delivered by the low pressure fuel pump or fuel
returned from the fuel pressure regulator.
This vapor is routed through the evaporation hose connecting the vapor separator cover to the silencer
cover.
HIGH PRESSURE FUEL PUMP
The high pressure fuel pump is an "integral" type in which the pump mechanism is located within the fuel
vapor separator.
To supply the optimum fuel amount, the pump is driven by the duty cycle signal from the ECM.
