J 37088-A tool set, Fuel Pipe Quick-Connect Separator
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.)
Notice: 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.
Notice: 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.
Notice: Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering the open pipes and passages.
Important: Always maintain cleanliness when servicing fuel system components.
Caution: In order to Reduce the Risk of Fire and Personal Injury: If nylon fuel pipes are nicked, scratched or damaged during installation, they must be replaced.
Notice: Always re-attach the fuel lines and fuel filter with all original type fasteners and hardware.
Do not repair sections of fuel pipes.Notice:
• Secure the fuel pipes to the frame in order to prevent chafing.
Maintain a minimum of 13 mm (½ inch) clearance around
a pipe in order to prevent contact and chafing. Maintain a minimum of 19 mm
(¾ inch) around any moving part. • Do not allow the fuel pipes to come into contact with the fuel
tank or underbody.
Important: If fuel line bundle attaching hardware is damaged or broken replace it.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
