Fuel Tank Replacement FWD

Removal Procedure

Caution: Provide additional support when a vehicle is on a hoist in the following ways:

   • 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: The fuel tank equipped with ORVR components require special handling. Follow all instructions for servicing the fuel tank as specified in the service procedures. Damage to the fuel system components and the failure to meet the Federal Regulations may result from incorrect servicing of the fuel tank.
