This bulletin outlines the procedure to repair fuel feed and return pipes.
^
A minimum of 13 mm (1/2") clearance must be maintained around sharp edges such as flanges, pinch weld, etc. to prevent contact and chafing. A
minimum of 19 mm (3/4") clearance must be maintained around any moving parts.
^
When rubber hose is used to replace pipe, use only reinforced fuel-resistant hose which is identified with the word "Fluorelastomer" or
"GM6163-M" on the hose such as those listed below. Hose inside diameter must match pipe outside diameter.

^
Do not use rubber hose within 100 mm (4") of any part of the exhaust system or within 254 mm (10") of the catalytic converter.
^
In the repairable areas, cut a piece of fuel hose 100 mm (4") longer than the portion of the line removed.
^
If more than a 6" length of pipe is removed, use a combination of steel pipe and hose so that the total hose lengths including the 100 mm (4")
additional length will not be more than 254 mm (10") long. Follow the same routing as the original pipe.
^
Cut ends of pipe remaining on car square with a tube cutter. Using the first step of a double flaring tool, form a bead on the end of both pipe
sections. If pipe is too corroded to withstand the beading operation without damage, the pipe should be replaced. If a new section of pipe is used,
form a bead on both ends of it also.
^
Use screw-type hose clamp, P/N 01648216 or equivalent. Slide clamps onto pipe and push hose 51 mm (2") onto each portion of fuel pipe.
Tighten clamps on each side of repair.
