WARNINGS:

* 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.

CAUTIONS:

* Do not attempt to straighten the kinked nylon fuel lines. Replace any kinked nylon fuel feed or return pipes in order to prevent damage to the vehicle.
* Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering the open pipes and passages.
* Always maintain cleanliness when servicing fuel system components.
* Do not attempt to repair sections of nylon fuel pipes. If the nylon fuel pipes are damaged, replace them.
