Fuel Tank: Service and Repair

SERVICE POINTS OF REMOVAL
5. DISCONNECTION OF FUEL HIGH-PRESSURE HOSE
Reduce the internal pressure of the fuel main pipes and hoses by using the following procedure.

NOTE: Be sure to reduce the internal pressure. If the hose is removed from the fuel main pipe without reducing the intrenal pressure, fuel will gush out.
(1) Start the engine, and then disconnect the electric fuel pump connector.
(2) After the engine has been stopped, set the ignition key to the "OFF" position.
(3) Disconnect the battery cable from the negative terminal of the battery.

INSPECTION
- Check the hoses and pipes for cracks, bends, deformation, deterioration or clogging.
- Check the fuel tank cap for operation.
- Check the fuel tank for deformation, corrosion or cracks.
- Check the fuel tank for entry of dust or foreign material.

NOTE: If the inside of the fuel tank is to be cleaned, use any one of the following:
(1) Kerosene
(2) Trichloroethylene
(3) A neutral emulsion type detergent

- Check the in-tank fuel filter for damage or clogging





CHECKING OVERFILL LIMITER (TWO-WAY VALVE)
A simple way of inspection, however, may be adopted in which the overfill limiter is removed and then air is lightly blown into either the inlet or outlet by mouth. If the air passes after a slight resistance, overfill limiter is in cood condition.





SERVICE POINTS OF INSTALLATION
6. CONNECTION OF FUEL VAPOR HOSE / 7. FUEL RETURN HOSE
When attaching the fuel hose to the pipe, be sure that the hose is attached as shown in the illustration.

Standard value : 25-30 mm (1.0-1.2 in.)





5. CONNECTION OF FUEL HIGH PRESSURE HOSE
When connecting the fuel high pressure hose to the fuel main pipe, tighten the flare nut by hand, and then tighten it to the specified torque, being careful that the fuel hose does not become twisted.
