Removal Procedure
Caution: In order to reduce the risk of fire and personal injury observe the
following items:
| • | Replace all nylon fuel pipes that are nicked, scratched or damaged
during installation, do not attempt to repair the sections of the nylon fuel
pipes |
| • | Do not hammer directly on the fuel harness body clips when installing
new fuel pipes. Damage to the nylon pipes may result in a fuel leak. |
| • | Always cover nylon vapor pipes with a wet towel before using a
torch near them. Also, never expose the vehicle to temperatures higher than
115°C (239°F) for more than one hour, or more than 90°C (194°F)
for any extended period. |
| • | Apply a few drops of clean engine oil to the male pipe ends before
connecting fuel pipe fittings. This will ensure proper reconnection and prevent
a possible fuel leak. (During normal operation, the O-rings located in the
female connector will swell and may prevent proper reconnection if not lubricated.) |
- Relieve
the fuel system pressure. Refer to the
Fuel Pressure Relief
.
- Clean all the fuel pipe connections and areas surrounding the
fuel pipe connections before disconnecting the fuel pipe connections in order
to avoid possible contamination of the fuel system.
- Disconnect the fuel pipes (2, 3) at the fuel rail. Refer to
Metal Collar Quick Connect Fitting Service
.
- Disconnect the evaporative emissions (EVAP) purge pipe (4) at
the EVAP canister purge valve.
- Remove the fuel and EVAP pipes from the retainers (1).
- Raise the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Disconnect the fuel return
pipe quick-connect fitting (1). Refer to
Plastic Collar Quick Connect Fitting Service
.
- Disconnect the EVAP purge pipe (2) at the EVAP canister.
- Disconnect the threaded fitting from the fuel filter (3)
outlet.
- Cap the fuel filter, the fuel feed pipe and the fuel return pipe
as needed in order to stop any fuel leakage.
- Remove the fuel and the
EVAP pipe bundle.
Installation Procedure
- Install the fuel and the
EVAP pipe bundle.
- Remove the caps from the fuel filter, the fuel feed pipe, and
the fuel return pipe.
- Connect the fuel return
pipe quick-connect fitting (1). Refer to
Plastic Collar Quick Connect Fitting Service
.
- Connect the EVAP purge pipe (2) at the EVAP canister.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Connect the threaded
fitting to the fuel filter (3) outlet. Use a back-up wrench in order to prevent
the fuel filter from turning.
Tighten
Tighten the fuel filter fitting to 30 N·m (22 lb ft).
- Lower the vehicle.
- Connect the fuel pipes
(2, 3) at the fuel rail. Refer to
Metal Collar Quick Connect Fitting Service
.
- Connect the EVAP purge pipe (4) at the EVAP canister purge valve.
- Install the fuel and EVAP pipes into the retainers (1).
- Tighten the fuel tank filler pipe cap.
- Connect the negative battery cable. Refer to
Battery Negative Cable Disconnection and Connection
in Engine Electrical.
- Inspect for leaks.
| 12.1. | Turn ON the ignition, with the engine OFF for 2 seconds. |
| 12.2. | Turn OFF the ignition for 10 seconds. |
| 12.3. | Turn ON the ignition, with the engine OFF. |
| 12.4. | Inspect for fuel leaks. |
- Install the fuel injector sight shield. Refer to
Fuel Injector Sight Shield Replacement
in Engine Mechanical-4.0L.
