Fuel pump
The fuel pump, which is mounted in the fuel tank, draws the fuel directly from the tank and pumps it to
the injector.
A filter that is provided in the fuel pump prevents any debris in the fuel tank from entering the fuel sys-
tem downstream of the pump.
The pump consists of a pump unit, electric motor, filter, and valves.
The pump unit is a Wesco type rotary pump that is connected to the motor shaft.
A relief valve is provided to prevent the fuel pressure from rising abnormally if the fuel hose becomes
clogged. This valve opens when the fuel pressure at the discharge outlet reaches between 441 and
637 kPa, and returns the fuel to the fuel tank.
