2. Plug the fuel pump module hose, ports B and C.
3. Apply compressed air at a pressure of 3 kPa (23 mm Hg) to port A and wait for some time.
4. Check the fuel tank for leaks. If air is leaking from the tank, replace the tank with a new one.
5. Plug the fuel pump module hose and port B.
6. Install the fuel tank level.
7. Apply compressed air at a pressure of 3 kPa (23 mmHg.) to port A and wait for some time.
8. Continuing to supply compressed air, make sure that it comes out through port C under a pressure of up to 3 kPa (up to 23 mm Hg.). If air does not come out, replace the fuel tank with a new one.

9. Create a vacuum of -0.5 kPa through port A (-3.8 mmHg.) and wait for a while.
10. While continuing to bleed the tank, make sure that air is being sucked in through port C. If air is not being sucked into the tank through port C, replace the fuel tank with a new one. If air is being sucked in, turn the fuel tank upside down.
11. While continuing to pump air out of the tank, make sure that air is not sucked in through port C when the tank is inverted. If air continues to be sucked in, replace the fuel tank with a new one.
