Fuel Hose/Pipes Assembly Replacement (Fuel Pipe Repair): Notes

Steel fuel lines-These are welded steel tubes, meeting GM specifications 124-M, or the equivalent. The fuel feed line is 9.5 mm (3/8 inches) diameter and the fuel return line is 8 mm (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 100 mm (4 in) of any part of the exhaust system, or within 2154 mm (10 in) 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.
