IMPORTANT:

When replacing the fuel pipes, always replace them with original equipment or parts that meet the GM specifications for those parts. The replacement pipes must have the same type of fittings as the original pipes in order to ensure the integrity of the connection.
Do not use copper or aluminum tubing to replace steel tubing. Only tubing meeting the 124-M specification or its equivalent is capable of meeting all pressure, corrosion and vibration characteristics necessary to ensure the durability standard required.

NOTE: Refer to Fastener Notice in Cautions and Notices.
