Removal Procedure

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: Do not attempt to straighten any kinked nylon fuel lines. Replace any kinked nylon fuel feed or return pipes in order to prevent damage to the vehicle.

Important: Important do not attempt to repair sections of nylon fuel pipes. If the nylon fuel pipes are damaged, replace them.
