Info needed: Fuel pump rebuild.....what time is it? modern fuels

[motto]

I have in past replaced the diaphragm re-using the original stem by drilling off the riveted end and then drilling and tapping the stem to take a screw or bolt. This has been quite successful.
I have no issues with the WW2 era mechanical, North American fuel pumps, most of which seem to be fitted with hand primers, so long as a suitable fuel compatible diaphragm is used.
I have in fact removed electric pumps installed by previous owners due to a potentially disastrous scenario involving a restored Dodge WC I once owned. The starter cable shorted on the fuel line and was perfectly capable of blowing a hole in it in which case the Auto Pulse would have pumped its little heart out until the ignition was turned off. Add to this that the vehicle was parked almost against my house and the loss could have been very great.
Modern vehicles with electric pumps have them powered in such a way as to cut power to them if the engine stops. They are not simply powered from the ignition.
This is to prevent an accident becoming a disaster.
