2.Remove the fuel tank and the fuel pump unit and the fuel gauge sender unit as a single unit. (See FUEL TANK REMOVAL/INSTALLATION [L3 Turbo].)

3.Perform the following procedure to verify the fuel tank airtightness.

(1)Plug the fuel pump unit pipe, ports B and C.

(2)Apply a pressure of 3 kPa {23 mmHg, 0.9 inHg} to port A and wait for a while.
(3)Verify that there is no air flow leakage from the fuel tank.
• If there is air flow, replace the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [L3 Turbo].)

4.Plug the fuel pump unit pipe and port C.

5.Level the fuel tank.

6.Apply a pressure of 3 kPa {23 mmHg, 0.9 inHg} to port A and wait for a while.

7.With the pressure still applied, verify that there is air flow port B and the pressure is 0—3 kPa {0—23 mmHg, 0—0.9 inHg}.

• If there is no air flow, replace the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [L3 Turbo].)

8.Apply a pressure of -0.5 kPa {-3.8 mmHg, -0.1 inHg} to port A and wait for a while.

9.With the pressure still applied, verify that there is air flow port B and the pressure is -0.5—0 kPa {-3.8—0 mmHg, -0.1—0 inHg}.

• If there is no air flow, replace the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [L3 Turbo].)
• If there is air flow, place the fuel tank upside down.

10.Apply a pressure to port A and wait for a while.
