Spark delay and sustain valves 1 Disconnect the vacuum pipes at the valve and withdraw the valve.
2 When refitting a spark delay valve, the valve must be positioned with the black end (marked “CARB”) towards the carburettor and the coloured end (marked “DIST”) towards the distributor or electronic module (as applicable).
3 When refitting a spark sustain valve, the valve must be positioned with the end marked “VAC” towards the carburettor and the side marked “DIST” towards the distributor or electronic module (as applicable).

4 Where fitted, the switch(es) may be located in the inlet manifold and/or in an adapter fitted in one of the coolant hoses.
5 To remove a switch, partially drain the cooling system. Note that there is no need to remove the cylinder block drain plug.
6 Mark the vacuum pipes for location so that they can be refitted in their correct positions, then disconnect the pipes from the switch.
7 Unscrew the valve from its location.
8 Refitting is a reversal of removal, ensuring that the vacuum pipes are correctly connected. Refill the cooling system.
9 Disconnect the vacuum pipes at the fuel trap and withdraw the fuel trap.
10 When refitting, the fuel trap must be positioned with the black end (marked “CARB”) towards the carburettor, and the white side (marked “DIST”) towards the distributor, electronic module, or ported vacuum switch (as applicable) (see illustration).
