INSPECTION
INSPECT FUEL TANK AND LINE
(a) Check the fuel lines for cracks or leakage, and all connec-
tions for deformation.
(b) Check the fuel tank vapor vent system hoses and connec-
tions for looseness, sharp bends or damage.
(c) Check the fuel tank for deformation, cracks, fuel leakage
or tank band looseness.
(d) Check the filler neck for damage or fuel leakage.
(e) Hose and pipe connections are as shown in the illustra-
tion.
If a problem is found, repair or replace the parts as necessary.
