Fuel Supply Line: Service and Repair
Fuel Hose and Assemblies
MATERIALS
FUEL LINES
These are welded steel tubes, meeting GM Specifications 124-M, or its equivalent. The fuel feed line is 3/8" diameter and the fuel return line is
5/16" diameter. Not use copper or aluminum tubing to replace steel tubing. Those materials do not have satisfactory durability to withstand
normal vehicle vibration.
COUPLED HOSE
These are not to be repaired and are replaced only as an assembly.
UNCOUPLED HOSE
Use only reinforced furl resistant hose, made of "Fluoroelastomer" material. Do not use a hose within 4" (100 mm) of any part of the exhaust
system, or within 10" (254 mm) of the catalytic converter. The hose's inside diameter must match the outside diameter of the steel tubing.
CLAMPS
These are stainless steel, screw bank-type clamps, #2494772, or equivalent.
