FUEL LINES AND CONNECTIONS
INSPECTION
(a) Check the fuel lines for cracks, leakage and all con±
nections for deformation.
(b) Check the fuel tank vapor vent system hoses and
connections for looseness, sharp bends or damage.
(c) Check the fuel tank for deformation, cracks, fuel leak±
age and tank band looseness.
(d) Check the filler neck for damage or fuel leakage.
(e) Hose and tube connections are as shown in the illus±
tration.
If a problem is found, repair or replace the part as
necessary.
PRECAUTIONS
1. Always use new gaskets when replacing the fuel
tank or component parts.
2. Apply the proper torque to all parts tightened.
