IMPORTANT NOTES
-
Steel fuel lines - These are welded steel tubes, meeting GM specifications 124-M, or its equivalent. The fuel feed line is 3/8 inches diameter and
the fuel return line is 5/16 inches diameter. Do not use copper or aluminum tubing to replace steel tubing. Those materials do not have satisfactory
durability to withstand normal vehicle vibration.
-
Coupled hose - Do not repair the hoses. Replace them only as an assembly.
-
Uncoupled hose - Use only reinforced fuel resistant hose, made of Fluoroelastomer material. Do not use a hose within 4 inches (100 mm) of any
part of the exhaust system, or within 10 inches (2154 mm) of the catalytic converter. The hoses inside diameter must match the outside diameter of
the steel tubing.
-
Clamps - These are stainless steel, screw bank-type clamps, #2494772, or equivalent.
