Evaporative Fuel Vapor Return Hose: Service and Repair
Fuel Vapor Pipe Replacement
CAUTION:
-
When replacing Evaporative Emissions (EVAP) pipes, always replace them with original equipment or parts that meet the GM specifications for
those parts.
-
Do Not use copper or aluminum tubing to replace steel tubing. Only tubing meeting the 124M specification or its equivalent is capable of meeting
all pressure and vibration characteristics necessary to ensure the durability standard required.
-
When replacing EVAP hoses or repairing sections of EVAP pipe with EVAP hoses, always replace them with original equipment or parts meeting
GM specifications, use only reinforced fuel-resistant hose which is identified with the word "Fluoroelastomer" or "GM 6163-M" on the hose.
Inside hose diameter must match outside pipe diameter.
-
Do Not use rubber hose within 100 mm (4") of any part of the exhaust system or within 254 mm (10") of the catalytic converter.
-
A minimum of 13 mm ("A") clearance must be maintained around sharp edges such as flanges, pinch welds, etc., to prevent contact and chaffing.
A minimum of 19 mm (3 / 4") clearance must be maintained around all moving parts.
REMOVE OR DISCONNECT
1. Hardware retaining section of pipe to be replaced.
-Note location of attaching hardware for installation.
2. Section of pipe and hoses.
Inspect
-
Hoses for cuts, swelling, cracks and distortion. Replace as required.
-
Pipes for bends, kinks and cracks. Repair or replace sections as required.
-
In the repairable areas, cut a piece of fuel hose 100 mm (4") longer than portion of the pipe removed. If more than a 152 mm (6") length of
pipe is removed, use a combination of steel pipe and hose so that the total hose lengths, including the 100 mm (4") additional length will not be
more than 254 mm (10") long.
INSTALL OR CONNECT
NOTICE:

Follow the same routing as the original hoses and pipes.
-
Hoses and pipes must be properly secured to prevent chafing.
