Fuel Pressure Checking
Warning - General - Fuel
warning
Observe the warning advice given in the General Information section on the safe handling of fuel and fuel containers. A fire, causing personal injury and damage to property could result from spilled fuel or fuel not handled or stored correctly.
Fuel pressure is checked using service tool T3880001.
T3880001 - Fuel Pressure Gauge |
- Remove the fuel tank (see Fuel Tank - Removal) and place on a suitable support, close to the motorcycle.
- Using the service tool T3880123, carefully connect the fuel pump connection on the main harness to the fuel tank.
- Select the fuel pressure gauge adapter marked B from service tool T3880001.
- Connect the adapter hose to the fuel pump plate outlet as shown in the illustration below.

- Ensure the gauge is visible to the side of the motorcycle.
- Temporarily reconnect the battery, positive (red) lead first and tighten the terminals to 4.5 Nm.
- Start the engine and observe the fuel pressure reading on the gauge.
- When fuel pressure checking is complete, disconnect the battery, negative (black) lead first.
- Disconnect the fuel pressure gauge adapter and wiring extension.
warning
Always use the correct fuel pressure gauge adapter. 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.
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.
note
The fuel pressure should be 3.5 bar nominally.
