Fuel Pump: Service and Repair

FUEL PUMP MODULE

Removal and Installation

WARNING:
- Do not smoke or carry an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited, resulting in possible personal injury.
- The evaporative emissions system contains fuel vapor and condensed fuel vapor. Although not present in large quantities, it still presents the danger of explosion or fire. Disconnect the negative battery cable from the battery to minimize the possibility of an electrical spark occurring, and possibly causing a fire or explosion if fuel vapor or liquid fuel are present in the area. Failure to follow these instructions can result in personal injury.
- Fuel in the fuel system remains under high pressure, even when the engine is not running. Before repairing or disconnecting any of the fuel system components, the fuel system pressure must be relieved to prevent accidental spraying of fuel causing personal injury or a fire hazard.
- The fuel in the tank may be pressurized. Remove the fuel tank cap slowly. If a hissing sound is heard, wait until the condition stops before removing the fuel tank filler cap. If these precautions are not followed, fuel may spray and cause personal injury.

1. Relieve the fuel pressure. See FUEL SYSTEM PRESSURE RELEASE.
2. Disconnect the battery ground cable. See BATTERY DISCONNECT.
3. Lift the LH rear seat cushion.

NOTE: It is necessary to lift the access cover on the floor scuff plate to access one of the pin-type retainers.




4. Position the carpet aside.




5. Remove the screws and the fuel pump module access cover.




6. Disconnect the electrical connectors.
7. Disconnect the fuel and vapor lines from the fuel tank. See QUICK RELEASE COUPLING - LOCKING TAB.




8. Remove the gas cap.




9. Rotate the lock ring counterclockwise and remove.

CAUTION:
- The fuel pump module must be handled carefully to avoid damage to the float arm and filter.
- Some fuel will remain in the fuel pump module after draining the fuel tank. Carefully drain the fuel pump module into a suitable container.




10. Prior to completely removing the fuel pump, position it aside and using a suitable fuel recovery system, drain the fuel tank.

NOTE: To release the bottom-mounted fuel pump module, reach into the fuel pump module opening and squeeze the retainer tabs or the pump module housing and pull upward.




11. Remove the fuel pump module.

NOTE: Be careful that no foreign material fall into the tank.

12. Remove and discard the fuel pump module O-ring seal, making sure the mounting area is clean and free from foreign material.

NOTE:
- Install a new fuel pump mounting gasket.
- When installing the fuel pump module, make sure to align the locator tabs on the fuel tank mounting flange.
- When installing the fuel pump module locking ring, hold the O-ring while turning the locking ring until it stops against the retainer tabs.

13. To install, reverse the removal procedure.
- Start the engine and visually inspect for leaks.
