Removal Procedure
Caution: In order to Reduce the Risk of Fire and Personal Injury:
• If nylon fuel pipes are nicked, scratched or damaged during installation,
Do Not attempt to repair the sections of the nylon fuel pipes. Replace them. • When installing new fuel pipes, Do Not hammer directly on the
fuel harness body clips as it may damage the nylon pipes resulting in a possible
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. • Before connecting fuel pipe fittings, always apply a few drops
of clean engine oil to the male pipe ends. 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.)
Caution: Provide additional support when a vehicle is on a hoist:
• Before removing parts, support the opposite end. This helps prevent
the vehicle from slipping off. • Before removing major components, chain the vehicle frame to the
hoist pads at the same end as the removal. This helps avoid a tip-off.
Notice: Do Not attempt to repair the EVAP pipes or the connecting hoses. Replace the damaged EVAP pipes or the connecting hoses are damaged. If the nylon EVAP pipe becomes kinked and cannot be straightened, it must be replaced.
Notice: Properly secure the EVAP pipe in order to prevent chafing of the pipe.
- Relieve the fuel system pressure. Refer to the Fuel Pressure Relief .
- Drain the fuel tank. Refer to Fuel Tank Draining .
- Remove the fuel tank. Refer to Fuel Tank Replacement .
- Remove the hardware retaining the EVAP pipes.
- Note the location of the retaining hardware for installation.
- Remove the EVAP pipes (3) at the EVAP canister (1). Refer to Plastic Collar Quick Connect Fitting Service .
- Remove the EVAP pipes at the fuel tank.
- Remove the EVAP pipes.
Installation Procedure
Notice: Always re-attach the fuel lines and fuel filter with all original type fasteners and hardware.
Do not repair sections of fuel pipes.Important: Route the replacement EVAP pipe in the same manner as the original pipe was routed.
- Install the fuel tank. Refer to Fuel Tank Replacement .
- Install the EVAP pipes to the chassis.
- Install the EVAP pipes (3) to the EVAP canister (1). Refer to Plastic Collar Quick Connect Fitting Service .
- Add fuel to the fuel tank.
- Install the fuel tank filler pipe cap.
- Install the negative battery cable.
- Inspect for leaks.

Notice: Properly secure the EVAP pipe in order to prevent chafing of the pipe.
| 7.1. | Turn the ignition switch to the On position for 2 seconds. |
| 7.2. | Turn the ignition switch to the Off for 10 seconds. |

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.
Tighten
Tighten the nuts to 3 N·m (27 lb in).
