FUEL SYSTEM
FUEL LINES. FUEL GAUGE TANK UNITS
All fuel lines are plastic and have an outside diameter
of ,240 inches. Unlike metal lines, plastic lines are
not flared.
When replacing a plastic line, place the line in hot
water to make it flexible. Using the old line as a
pattern, form the new line. Let the line cool com-
pletely, then route it in the same location as the old
line. To prevent chafing against the underbody, nine
(9) rubber grommets are placed at points on the line
between the fuel tank and the fuel pump. When re-
placing fuel gauge tank units, coat gasket on both
sides and first threads of attaching screws with seal-
ing compound.
CLEANING FUEL TANK
1. Remove fuel tank.
2. Empty fuel tank through filler neck.
