Fuel system (1.6 and 1.8 litre (R6A type) CVH) - depressurisation

Remember to depressurise the fuel system before loosening any connections.

Refer to the precautions in Section 1 before proceeding. The fuel system will remain pressurised after the engine is switched off.

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 (see illustration). 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.
