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.) |
Notice: Cap the fittings and plug the holes when servicing the fuel system in
order to prevent dirt and other contaminants from entering the open
pipes and passages.
- Relieve the fuel system
fuel pressure. Refer to
Fuel Pressure Relief
.
- Clean all the engine fuel pipe connections and areas surrounding the
connections before disconnecting the pipes to avoid contamination of the
fuel system.
- Disconnect the fuel feed (1) fuel return (5) quick-connect
fittings from the fuel rail. Refer to
Metal Collar Quick Connect Fitting Service
.
- Raise the vehicle. Refer
to
Lifting and Jacking the Vehicle
in General Information.
- Disconnect the fuel line on the engine-side of the in-line fuel
filter. Refer to
Plastic Collar Quick Connect Fitting Service
.
- Cap the in-line fuel filter pipe, the fuel feed pipe, and the
fuel return pipe as needed to stop any fuel leakage.
Important: You may need to partially lower the engine cradle.
- Remove the fuel feed, the fuel return, and the evaporative emission
(EVAP) pipe attaching hardware and pipes. Note the position of the hardware
for the installation.
- Inspect the pipes for bends, kinks, and cracks.
- Repair or replace the pipes as required.
Installation Procedure
Caution: In order to reduce the risk of fire and personal injury observe the

| • | 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.) |
Notice: Always re-attach the fuel lines and fuel filter with all original type
fasteners and hardware.
Do not repair sections of fuel pipes.
Notice:
| • | Secure the fuel pipes to the frame in order to prevent chafing.
Maintain a minimum of 13 mm (½ inch) clearance around
a pipe in order to prevent contact and chafing. Maintain a minimum of 19 mm
(¾ inch) around any moving part. |
| • | Do not allow the fuel pipes to come into contact with the fuel
tank or underbody. |
- Install the new fuel feed,
fuel return, and EVAP pipes and attaching hardware as noted during the removal.
- Remove the caps from the in-line fuel filter pipe, the fuel feed
pipe, and the fuel return pipe.
- Install the new plastic connector retainers on the fuel pipes.
- Connect the line at the in-line fuel filter. Refer to
Plastic Collar Quick Connect Fitting Service
.
- Lower the vehicle.
- Connect the fuel feed (1) and fuel return (2) line
quick-connect fitting to the fuel rail. Refer to
Metal Collar Quick Connect Fitting Service
.
- Connect the negative battery cable. Refer to
Battery Negative Cable Disconnection and Connection
in Engine Electrical.
- Perform the following procedure to inspect for fuel leaks:
| 8.1. | Turn ON the ignition for 2 seconds. |
| 8.2. | Turn OFF the ignition for 10 seconds. |
| 8.3. | Turn ON the ignition. |
| 8.4. | Inspect for fuel leaks. |
- Install the fuel injector
sight shield. Refer to
Fuel Injector Sight Shield Replacement
in Engine Mechanical.
