I have been thinking of adding a electric fuel pump in line on the 36 as insurance or even a priming pump on a momentary switch. The car will be 12v.
I think I already know this won’t work but I have a couple of new airtex 6v pumps. What happens to a 6v pump with 12v? Pump twice as fast, same pressure? Catch fire? Probably be okay for a priming pump? I guess it would be cheaper to get a 12 volt pump than to reduce the Voltage in the long run.

When I get the car on the road I will probably have a spare mechanical pump in the trunk along with a coil and anything else that could be done with a road side repair.
