 == Fuel Pressure ==
-Located beneath rear of plenum chamber. Function is to reduce fuel pressure on 'overun' and idle. A micro-switch, mounted on the front of the front carburettor, and operated by the throttle lever in its fully closed position, energises the fuel pressure solenoid. The signal to the fuel pressure regulator (normally connected to boost pressure in the plenum chamber) is then switched to No.1 cylinder inlet manifold depression, thus reducing
-fuel pressure to the carburettors and mixture strength under closed throttle 'overun' conditions.
