FUEL PUMP MODULE
DESCRIPTION
The fuel pump module is installed in the top of the fuel tank.
The fuel pump module contains the following:
•
Electric fuel pump
•
Fuel pump reservoir
•
Inlet strainer
•
Fuel pressure regulator
•
Fuel gauge sending unit
•
Fuel supply line connection
•
Fuel Filter
NOTE: The fuel level sensor and the pressure regulator are the only serviceable items. If the fuel pump or
electrical wiring harness requires service, replace the fuel pump module.
OPERATION
The pump draws fuel through a strainer and pushes it through the motor to the outlet. The pump contains one
check valve. The check valve, in the pump outlet, maintains pump pressure during engine off conditions. The fuel
pump relay provides voltage to the fuel pump.
The fuel pump has a maximum deadheaded pressure output of approximately 880 kPa (130 psi). The regulator
adjusts fuel system pressure to approximately 400 ±34 kPa (58 ±5 psi).
FUEL PUMP ELECTRICAL CONTROL
Voltage to operate the electric pump is supplied through the fuel pump relay. For an electrical operational descrip-
tion of the fuel pump refer to fuel Pump Relay—PCM Output.
ELECTRICAL PUMP REPLACEMENT
The electric fuel pump is not serviceable. If the fuel pump or electrical wiring harness needs replacement, the com-
plete fuel pump module must be replaced. Perform the Fuel System Pressure Release procedure before servicing
the fuel pump.
