Attention:
- When working on the fuel tank or fuel lines, smoking or using open flames in the workplace is not permitted.
- Be careful not to spill fuel when disconnecting the fuel connectors.
- When performing work, use leak-resistant nitrile gloves and goggles with side protection.
- To prevent contaminants from entering the fuel system circuit, use plugs to seal the openings of disconnected components.
- To avoid corrosion or damage, it is necessary to take measures to protect surfaces that may come into contact with leaking fuel
Checking the fuel supply
1. Place the vehicle on a two-stop lift.
2. Turn off the ignition.
Version A
Disconnect the fuel pressure line connector (3).
4. Connect the T-piece to check the fuel pressure (Mot. 1311-08) (6) to the fuel tank outlet pipe.
5. Connect the hose (5) from the fuel pressure gauge kit (Mot. 1311-01) to the T-shaped connecting element (6).
6. Connect the fuel supply line (7) to the T-shaped connector (6).
7. Insert the end of the hose (11) into a graduated measuring cylinder (2000 ml).
8. Remove the relay and fuse box cover.
9. Remove the relay (12).
10. Close the circuit across the relay to supply power to the electric fuel pump.
Note: Fuel supply should be 75~95L/H
11. Insert the fuel pump relay into the relay and fuse box.
12. Install the relay and fuse box cover.
Version B
13. Disconnect the fuel pressure line connector (4).
14.Connect the T-shaped connector to check the fuel pressure (Mot. 1311-08) (8) to the fuel tank outlet pipe.
15. Connect the hose (9) from the fuel pressure gauge kit (Mot. 1311-01) to the T-shaped connecting element (8).
16. Connect the fuel supply line (10) to the T-shaped connector (8).
17. Insert the end of the hose (11) into a graduated measuring cylinder (2000 ml).

18. Disconnect the connector (13) from the vehicle interior wiring harness.
19. Connect the connector terminal (13) to the positive terminal of the battery to turn on the fuel pump.
20. Record the time it takes for the graduated cylinder to fill and calculate the amount of fuel supplied.
Note: Fuel supply should be 75 - 95 l/hour.
21. Disconnect the power supply from the connector terminal (13).
Continuation for all versions
22. Disconnect the T-shaped connector.
23. Connect the fuel supply line to the fuel tank outlet pipe.
