Repair Procedure (Continued)
3. Confirm the fuel pump resistor connector is fully seated.
4. If no concerns are noted with the fuel pump resistor connector or fuel pump circuit, replace
the following components:
• Fuel Pump
• Fuel Pump Filter
• Fuel Suction Plate Sub-Assembly
• Fuel Tank Solenoid Main Valve Assembly
NOTE
When removing the fuel suction plate sub-assembly, confirm the original fuel pump pressure
port O-ring and spacer did not separate from the suction plate and stay in the fuel filter
housing assembly. If the O-ring and spacer did separate from the suction plate, remove and
discard them prior to installing a new suction plate.
