Fuel Supply Line: Service and Repair

FUEL LINES






















Removal

WARNING:
- Do not smoke or carry lighted tobacco or 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 battery ground 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.

1. With the vehicle in NEUTRAL, position it on a hoist.
2. Release the fuel system pressure.
3. Disconnect the battery ground cable.
4. Disconnect the fuel rail-to-fuel supply tube quick connect coupling primary locking tab.
5. Disconnect the remaining fuel supply tube quick connect coupling and remove the fuel supply tube.
6. Disconnect the fuel vapor tube quick connect couplings from the intake manifold and the evaporative emissions (EVAP) canister purge valve and remove the fuel vapor tube.
7. Disconnect the fuel vapor tube quick connect coupling from the EVAP canister purge valve.
8. Disconnect the fuel supply jumper tube quick connect coupling.
9. Disconnect the fuel vapor tube quick connect from the EVAP canister.
10. Release the fuel supply and fuel vapor tubes from the frame-mounted retainer clip.







11. Unclip the fuel tube retainer clip from the mounting stud to service the fuel supply and vapor tubes as an assembly. The retainer clip will also open to service the tubes individually.
- Remove the fuel supply and fuel vapor tubes from the vehicle.

Installation
1. Install the fuel supply tube and fuel vapor tubes.
- Make sure the retainer clips snap into place when installing onto the studs. Pull on the clips to make sure they are correctly seated.

2. NOTE: Make sure the tubes are correctly snapped into the clip and the clip is snapped securely into the subframe.

Install the fuel supply and fuel vapor tubes into the frame-mounted retainer clips.

3. Connect the fuel vapor tube quick connect coupling onto the EVAP canister.
4. Connect the fuel supply jumper tube quick connect coupling.
5. Connect the fuel vapor tube quick release coupling to the EVAP canister purge valve.
6. Install the fuel vapor tube and connect the fuel vapor tube quick connect couplings to the intake manifold and the EVAP canister purge valve.
7. Install the fuel supply tube and connect the quick connect coupling.
8. Connect the fuel tube-to-fuel rail quick connect coupling.
9. Connect the battery ground cable.
10. Turn the ignition key to the ON position to pressurize the fuel system.
11. Visually inspect the fuel system for leaks.
