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. CAUTION: When reusing liquid or vapor tube connectors, make sure to use compressed air to remove any foreign material from the connector retaining clip area before separating the tube.

NOTE: Carefully release the locking tabs to avoid breakage.

Release the fuel rail-to-fuel supply tube quick connect coupling primary locking tab.







5. Rotate the primary locking tab to the fully opened position and squeeze the secondary locking tabs to release the locking mechanism.







6. Push the locking mechanism outward and release the fuel supply tube.







7. CAUTION: When reusing liquid or vapor tube connectors, make sure to use compressed air to remove any foreign material from the connector retaining clip area before separating the tube.

NOTE: If the vapor tube or retainer clip is broken or damaged, install a suitable fuel tube disconnect tool to separate the retainer clip legs. Once the retainer clip legs have separated, lift the clip out of the connector housing, lifting the stamped side of the connector body.

Disconnect the remaining fuel supply tube quick connect coupling and remove the fuel supply tube.
- Push the connector toward the tube to release the pressure.
- Press the fuel supply tube quick connect coupling button and pull the fuel supply tube to disconnect.
- Remove the fuel supply tube.

8. To access fuel vapor quick connect coupling on the intake manifold, remove the LH lower splash shield.







9. CAUTION: When reusing liquid or vapor tube connectors, make sure to use compressed air to remove any foreign material from the connector retaining clip area before separating the tube.

NOTE: If the vapor tube or retainer clip is broken or damaged, install a suitable fuel tube disconnect tool to separate the retainer clip legs. Once the retainer clip legs have separated, lift the clip out of the connector housing, lifting the stamped side of the connector body.

Disconnect the fuel vapor tube quick connect couplings from the intake manifold and the emissions canister purge valve.
- Push the connector toward the tube to release the pressure.
- Press the fuel vapor tube quick connect coupling button and pull the fuel vapor tube to disconnect.

10. Detach the fuel vapor tube retainers.
- Remove the fuel vapor tube.







11. CAUTION: When reusing liquid or vapor tube connectors, make sure to use compressed air to remove any foreign material from the connector retaining clip area before separating the tube.

Disconnect the fuel vapor tube quick connect coupling from the evaporative emissions (EVAP) canister purge valve.
1 Press the fuel vapor tube quick connect coupling locking tabs.
2 Disconnect the fuel vapor tube quick connect coupling.







12. CAUTION: When reusing liquid or vapor tube connectors, make sure to use compressed air to remove any foreign material from the connector retaining clip area before separating the tube.

Disconnect the fuel supply jumper tube and the fuel vapor tube quick connect couplings.
1 Press the quick connect coupling locking tabs.
2 Disconnect the fuel supply jumper tube and the fuel vapor tube quick connect couplings.

13. Release the fuel supply and fuel vapor tubes from the frame-mounted retainer clip.







14. 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. NOTE:
- Make sure the collar on the fuel tube is inserted fully into the quick connect coupling before the locking tab is locked.
- Apply clean engine oil to the end of the tube before inserting a tube into the connector.

Connect the fuel supply jumper tube and the fuel vapor tube quick connect couplings.
1 Connect the quick connect couplings.
2 Press the quick connect coupling locking tabs into position.
- Pull on the fittings to make sure they are fully engaged.







4. NOTE:
- Make sure the collar on the fuel tube is inserted fully into the quick connect coupling before the locking tab is locked.
- Apply clean engine oil to the end of the tube before inserting a tube into the connector.

Connect the fuel vapor tube quick connect coupling to the EVAP canister purge valve.
1 Connect the quick connect couplings to the EVAP canister purge valve.
2 Press the quick connect coupling locking tab into position.
- Pull on the fitting to make sure it is fully engaged.

5. Install the fuel vapor tube.
- Attach the fuel vapor tube retainers.







6. CAUTION: Make sure the fuel vapor tube clicks into place when installing the tube. To make sure the tube is fully seated, pull on the tube.

NOTE: Apply clean engine oil to the end of the tubes before inserting the tubes into the connectors.

Connect the fuel vapor tube quick connect couplings to the intake manifold and the EVAP canister purge valve.

7. Install the LH lower splash shield.







8. CAUTION: Make sure the fuel supply tube clicks into place when installing the tube. To make sure the tube is fully seated, pull on the tube.

NOTE: Apply clean engine oil to the end of the tube before inserting a tube into the connector.

Install the fuel supply tube and connect the quick connect coupling.

9. NOTE:
- Make sure the collar on the fuel tube is inserted fully into the quick connect coupling before the locking tang is locked.
- Apply clean engine oil to the end of the tube before inserting a tube into the connector.

Connect the fuel tube to fuel rail quick connect coupling.
- Connect the quick connect coupling to the tube.
- Press the quick connect coupling locking tab into position.
- Pull on the fitting to make sure it is fully engaged.

10. Connect the battery ground cable.
11. Turn the ignition key to the ON position to pressurize the fuel system.
12. Visually inspect the fuel system for leaks.
