Should I install an electric fuel pump in my 61 Valiant?

Mechanical fuel pump works ok, but as I drive the car infrequently I need to prime the cabbie to make starting easier.

My mechanic says not the best idea to install an electric fuel pump; later models yes, but not in the 61'.

Only subjective, but I run electrics in all my slants. Though always with a regulator to keep the pressure below 3 lbs., as I don't trust'em. It's a necessity with the SUs I like, but the BBSs & BBDs I've run liked'em as well. We also run the same on the BBS on our animation slant on the Rose float.

The real solution here is to drive your car more often and enjoy it.

I understand your problem, which an electric pump would cure. But only use an electric pump, if it is installed correctly. If I were doing it, I would install as a "primer" pump, only. Mount the pump near the tank, and protected from road debree. Wire with a fuse/circuit breaker, and with a momentary switch, to energise the pump to prime the carb only.

Read this before you put on an electric pump.

Yeah... I'd never trust the carb's needle and seat to be the pressure regulator, or the fuel pump reaching its maximum pressure to limit things. Always use a pressure regulator. I'm even a fan of bypass-style regulators on carbs, basically an EFI type regulator with a lower set pressure and return line. However, with a stock-ish slant six and a carb, I would prefer a mechanical pump for simplicity.

Do you know what brand or type of regulator you use?
