I recommend the use of a low pressure electric fuel pump on any older collector car as a supplement to the mechanical pump. If your mechanical pump and carburetor components are in good shape, the addition of the electric pump will not cause problems, and will make the car much more serviceable.
I have several old (pre-war) cars, and have gradually installed supplemental electric fuel pumps on the ones that I drive regularly. I install a suitably low pressure electric fuel pump, near the fuel tank, to feed coolest possible fuel to the mechanical pump. This enables me to effectively prime the engine when it has not been run in awhile, reducing cranking load on the battery and starter etc.
In a couple of cases, adding the supplemental pump caused the original fuel pump to leak. These leaks were due to ethanol in modern fuels consuming the rubber diaphragm of the mechanical pump. I then rebuild the mechanical fuel pump with Viton (ethanol resistant) components which solved the problem. Newer fuel pump rebuilding kits will contain Viton (or other ethanol resistant) components.
A related issue is that ethanol laced fuels also damage the accelerator pump components in the carburetor, necessitating rebuilding the carburetor with Viton soft parts.
