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.

1. Relieve fuel system pressure. Refer to Fuel Pressure Relief .

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.

Failure to follow these precautions could cause vehicle damage, serious personal injury, or death.

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.
