Is it normal for the electric pump on a Plus 8 (1970s) to tick all the time? I can understand why you might hear it ticking/pumping when you initially turn the ignition on and the carburettor/fuel lines etc are filling up, but I would have expected that to stop after a few seconds (without actually starting the engine). Or does the pump tick (ie run) all the time even when there is no actual fuel flow into the carb? (There is no return fuel line from the carb).
