Fuel and Vapor Return Tubes
Plastic
CAUTION: Ford-approved nylon fuel tubing is made from material which has been tested and
proven to be acceptable for use with commercially available fuels. It is also resistant to most
environmental conditions. Avoid using alternate tubing materials. Use of non-approved tubing could
pose a hazard in service.
CAUTION: Plastic fuel tube must not be repaired using hose and hose clamps. Push connect
fittings cannot be repaired except to replace the retaining clips.
CAUTION: The plastic fuel lines can be damaged by torches, welding sparks, grinding and
other operations which involve heat and high temperatures. If any repair or service operation will be
used which involves heat and high temperatures, locate all fuel system components, especially the
plastic fuel lines to be certain they will not be damaged. It is recommended that the plastic fuel tubes
be removed from the vehicle if a torch or high heat producing equipment is to be used for service in
the following areas:
1. Exhaust or suspension components in proximity to fuel tubes.
2. Underbody, rails and crossmembers (left side).
3. Dash panel; under vehicle or inside the passenger compartment (lower right side).
4. Front or rear wheel house/fender apron (right side).

In a high heat environment, Teflon® hose and stainless steel tubes with crimped joints are used. These
tubes have been tested, and proven to be acceptable for use with commercial fuels. Avoid using alternate
tubing materials. Use of non-approved tubing could pose a hazard in service.
CAUTION: Teflon® hose and stainless steel fuel tube assemblies must not be repaired using
hose and hose clamps. If damaged, they must be replaced.
