Fuel Filter: Service and Repair

REMOVAL PROCEDURE

TOOLS REQUIRED

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.
