Lumina V6-3100 3.1L VIN M SFI (1995)
Evaporative Fuel Vapor Return Hose: Description and Operation
The fuel vapor line is made up of nylon line, rubber connection hoses and steel pipe. The vapor pipe, line, and hoses carry fuel vapors from the fuel tank
to the charcoal canister.
The vapor lines extend from the fuel gage 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 hoses are specially manufactured and if replacement becomes necessary, it is important to use only the service replacement hoses
identified with the word Fluoroelastomer.
