Warning: Observe the fuel handling precautions given in the general information section.
Fuel pressure is checked using service tool T3880001.
Tool T3880001
1. Remove the rider's seat (see page 16-13).
2. Remove the fuel tank (see page 10-91) and place on a suitable support, close to the motorcycle.
3. Using the extension cable T3880123, carefully connect the fuel pump connection to the fuel tank. Connect the other end of the extension cable to the motorcycle main harness.
4. Select the fuel pressure gauge adapter marked 'B' from service tool T3880001.
Warning: Always us the correct fuel pressure gauge adapter (adapter 'B' for Tiger 800 and Tiger 800XC). Use of an incorrect adapter will result in a fuel leak. A fuel leak can result in a fire causing damage to property and injury to persons.
5. Connect the adapter hose to the fuel pump plate outlet as shown in the illustration below.
1. Adaptor hose 'B'; 2. Fuel pump plate outlet; 3. Extension cable T3880123
6. Connect the fuel hose to the adaptor hose as shown in the illustration below.
1. Motorcycle fuel hose; 2. Adaptor hose 'B'; 3. Wiring extension T3880123; 4. Fuel pump connection; 5. Fuel pump plate outlet
7. Connect the fuel pressure gauge to the adaptor hose as shown below by pushing the gauge spigot into adapter until a click can be heard.
1. Adaptor hose; 2. Fuel pressure gauge
Note: To release the fuel pressure gauge from the adapter, slide the outer ferrule downwards. This will allow the gauge to spring upwards from the adapter.
8. Ensure the gauge is visible to the side of the motorcycle.
9. Start the engine and observe the fuel pressure reading on the gauge.
Note: The fuel pressure should be 3.0 bar nominally.
10. When fuel pressure checking is complete, disconnect the fuel pressure gauge adapter and wiring extension.
11. Refit the fuel tank (see page 10-92).
12. Refit the rider's seat (see page 16-13).
