Fuel system - depressurising
Warning: The fuel system will remain pressurised after the engine is switched off. Comply with all relevant safety precautions during this operation and refer to the “Safety first!” Section at the beginning of this manual before proceeding.
1 Disconnect the battery negative lead.
2 Remove the air cleaner assembly.
3 Position a suitable container or a sufficient quantity of absorbent cloth beneath the fuel inlet connection on the CFI unit.
4 Use an open-ended spanner on the flats of the inlet union screwed into the CFI unit to prevent it from turning while the inlet pipe union is loosened. Allow all pressure/fuel seepage to dissipate before fully unscrewing the union if it is to be disconnected, or tightened if another part of the system is to be worked on.
5 The system will remain depressurised until the fuel pump is primed prior to starting the engine. Remove the container or cloth, as applicable, on completion.
