CLEANING AND INSPECTION

Fuel Tanks

 CAUTION: Leaks or damage to the polyethylene fuel tanks (9002) are not repairable. This applies to certain F-Series vehicles with a plastic fuel tank including all polyethylene portions of the fuel tank body and fittings. Fuel tank replacement is the only acceptable service. There are no reliable repair products that meet the same standards as a new fuel tank. Methods which appear to work may not function for the long term or after being subjected to normal use or abuse.

Fuel tanks may be steam-cleaned and/or serviced using standard procedures. After steaming, allow time to thoroughly air dry. The evaporative emission valve (9B593) and fuel tank sending unit and pump should be removed prior to steaming.
