Thanks.
Mine is tapped off at the banjo joint on the carburettor float bowl. The
warning light can flicker when taxiing across rough ground (as the float
valve bounces open and relieves fuel line pressure in the near vicinity of
the carb) and when there is any vapour passing through the system (despite
the presence of the vapour return). The latter feature is useful and
disappears when the second pump is turned on.
