Evaporative Fuel Vapor Return Hose: Description and Operation
FUEL VAPOR PIPE, LINE
The fuel vapor line is made up of nylon line, steel pipe, and quick connectors. The vapor pipe, line, and hoses carry fuel vapors from the fuel tank
to the charcoal canister.
The vapor lines extend from the fuel sender to the canister. However, it does not follow the same route as the fuel feed pipe.
Under no conditions use copper or aluminum tubing to replace steel tubing. Those materials do not have satisfactory durability to withstand
normal vehicle vibrations and corrosion.
NOTICE:
The nylon lines are specially manufactured and if replacement becomes necessary, it is important to use only the correct service part. Do not cut
and replace them with rubber hose.
WARNING:
To Reduce the Risk of Fire and Personal Injury: Always cover nylon fuel lines with a wet towel before using a torch near it. Also, never
expose the vehicle to temperatures higher than 115° C (239° F) for more than one hour, or more than 90° C (194° F) for any extended
period.
Take care not to nick or scratch the fuel pipes. If damaged, it must be replaced.
