Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual pressure
in the fuel pipe line.
INSPECTIONN14GCAHl Check the hoses and the pipes for crack or damage.
l Check the fuel tank cap for malfunction.
l Check the fuel tank for deformation, corrosion or crack.
l Check the fuel tank for dust or foreign material.
NOTE
If the inside of the fuel tank is to be cleaned, use any one ofthe following:
(1) Kerosene
(2) Trichloroethylene
(3) A neutral emulsion type detergent
OVERFILL LIMITER (TWO-WAY VALVE)
Set a hand vacuum pump at inlet side or outlet side; the valve
is good if, when a negative pressure (vacuum) is applied, air
flows after a slight negative pressure is initially maintained.
