I might be talking through my hat here (but I don't think so).  Electric
fuel pumps in marine engines tend to be operated by a switch that only runs
them when it sees oil pressure.  The AFC system in the '81 vgon does this
by looking at Hall pulses or some such -- but if it's been converted to
carbs there is no AFC system.  I suspect that your DPO just hooked the pump
up to the ignition switch, not too safe if there's an accident.
