SUBJECT: FUEL LINE O-RINGS
MODELS AFFECTED: 1982-1985 MODELS
The fuel line O-rings (feed and return lines) used on many 1982-1985 engine applications are made of Viton. The Viton O-rings (Viton is a type of rubber) are brown in color. They are less affected than rubber by the additives used in many of the fuel blends available today and therefore should not be substituted with other type rubber O-rings. The following are the part numbers used on the above applications:
