If you need fuses, I get them from Harbor Freight. $30 will get you pretty much a lifetime supply of glass and both blade sizes, no matter your age.

I have one on my 37 to assist getting the system primed after sitting for a time. (like months......)
I used a single pull double pull momentary/off/on switch, (SPDT )
This allows me to push the momentary contact to prime the carb and release then if needed I can place it in contant run .
It is powered from main power ( forget actual point) but the car is equipped with a battery cut off switch.

A common modern type diaphragm pump would work just as well for priming a system that has been stored.

Mount it somwhere where it can be reached and put a 6" lever on the actuator arm so that it can be manually operated. The regular stock pump should be able to pull fuel through it with no problem.

Ideally, it would be mounted under the trunk area on the frame near the gas tank and away from the exhaust, with a linkage/handle arrangement to operate it from within the trunk. A good quality choke cable or PTO cable might do to operate it.

I'd mount it in its normal upright position, and a little higher than the top of the fuel tank and locate the operating knob or handle in an out of the way spot in the trunk. Something like a coffee can could be used to make a dust/splash shield for the pump.
