Fuel Return Line: Service and Repair
Fuel Hose/Pipes Replacement - Filter to Engine
FUEL HOSE/PIPES REPLACEMENT - FILTER TO ENGINE
REMOVAL PROCEDURE
1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure.
CAUTION: In order to Reduce the Risk of Fire and Personal Injury:
-
If nylon fuel pipes are nicked, scratched or damaged during installation, Do Not attempt to repair the sections of the nylon fuel pipes.
Replace them.
-
When installing new fuel pipes, Do Not hammer directly on the fuel harness body clips as it may damage the nylon pipes resulting in a
possible fuel leak.
-
Always cover nylon vapor pipes with a wet towel before using a torch near them. 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.
-
Before connecting fuel pipe fittings, always apply a few drops of clean engine oil to the male pipe ends. This will ensure proper
reconnection and prevent a possible fuel leak. (During normal operation, the O-rings located in the female connector will swell and may
prevent proper reconnection if not lubricated.)
NOTE:
-
Do not attempt to straighten any kinked nylon fuel lines. Replace any kinked nylon fuel feed or return pipes in order to prevent damage to the
vehicle.
-
Replace the EVAP pipes and hoses with the original equipment or parts that meet the GM specifications for those parts. The replacement EVAP
pipe must have the same type of fittings as the original pipe in order to ensure the integrity of the connection. When replacing EVAP hoses, use
only reinforced fuel-resistant hose identified with the word Fluoroelastomer or GM 6163-M on the hose. The inside hose diameter must match the
outside pipe diameter. Do not use rubber hose within 100 mm (4 in) of any part of the exhaust system or within 254 mm (10 in) of the catalytic
converter.
-
Refer to Cover and Plug Openings Notice in Service Precautions.
IMPORTANT: Always maintain cleanliness when servicing fuel system components.
2. Clean all engine fuel pipe connections.
3. Clean areas surrounding the engine fuel pipe connections.
4. Disconnect the fuel feed and fuel return pipe quick-connect fitting in the engine compartment.
