Removal

Warnings:
When removing components such as the fuel tank, rear suspension, etc., use a garage lift under the front of the vehicle to prevent it from tipping over.
When working on the fuel tank, make sure the ignition is off. Avoid any heat sources or sparks, such as lights, smoking, etc.
Before working on the fuel tank or lines, remove the filler cap to relieve excess pressure from the tank.

1. Disconnect the fuel tank connector after removing the rear seat cushion.

2. Remove the drain plug from the fuel tank to drain the fuel.

Note: Do not remove the filter located in the fuel tank unless the filter is being replaced.

3. Loosen the fuel hose clamps (main and return) and disconnect the fuel hoses:

4. Disconnect the hose, necks and air hose from the filler neck.

5. After removing the fuel tank mounting tape, slowly lower the fuel tank, then disconnect the wiring from the fuel gauge sensor.

6. Remove the fuel tank.

Examination

Check the following (and replace defective parts if necessary):

1. Leaks from the fuel tank.

If leaks are found, clean the fuel tank from dirt inside and outside and check for rust, corrosion, damage and cracks. A heavily corroded or damaged fuel tank must be replaced.

2. Is the fuel line clogged, damaged or corroded?.

Note: When cleaning the fuel tank, avoid using cleaners that may affect the tin coating on the inside of the fuel tank. Use trichloroethylene, neutral emulsion type cleaning fluid, etc.

3. Peeling or damage to the lining at the top of the fuel tank.

4. Checking the operation of the two-way valve.

To check the two-way valve, blow lightly into the inlet and outlet ports. If air passes through the valve with little resistance, the valve is OK.
