Inspection 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.)
Caution: Do not breathe the air through the EVAP component tubes or hoses. The fuel vapors inside the EVAP components may cause personal injury.
- Lightly tap the EVAP canister purge valve on a hard surface.
- Inspect for contamination exiting either of the vacuum ports.
| • | If contamination is detected, continue with the cleaning procedure. |
| • | If no contamination is detected, return to the published service procedure. |
Cleaning Procedure
- Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
- Remove the EVAP canister. Refer to Evaporative Emission Canister Replacement .
- Use low air pressure to dislodge any contamination in the EVAP chassis purge pipe.
- If the air does not dislodge the carbon particles, replace the purge pipe. Refer to Evaporative Emission Hoses/Pipes Replacement - Chassis/Canister .
- Install a new EVAP canister. Refer to Evaporative Emission Canister Replacement .
- Lower the vehicle.
- Return to the published service procedure.
Important: Do not exceed 4 Hg (2 PSI).
