Steel Fuel Line Repair
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 (254 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.
PROCEDURE
1. Cut a piece of fuel hose 4 inches (100 mm) longer than the section of line to be removed. If you remove more than 6 inches (152 mm), use a
combination of steel pipe and hose. The hose length should not be more than 10 inches total.
2. With a tube cutter, cut a section of the pipe to replace. Use the first step to form a bead on the ends of the pipe and, also, on the new section of
pipe, if used.
3. Slide the hose clamps onto the pipe and push the hose 2 inches (51 mm) onto each portion of the fuel pipe. Tighten a clamp on each side of the
repain
4. Secure fuel line to the frame.
5. Check for leaks.
