What do you guys think is the shelf life of a rebuilt fuel pump for a 1962 235.

It would depend on the environmental conditions that the shelf experiences. Cool and dry - Good. Hot and moist - probably not so good.
You'd probably have to pull the fuel pump apart and look at the condition of the diaphragm. If it's cracked, it would need to be replaced.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.

How long ago was it rebuilt? If more than 10 years or so, it probably doesn't have an ethanol resistant diaphragm even if the rubber isn't cracked or dried out.

I'd plan on rebuilding it if you're uncertain of the rebuild date.

If it has been stored in a shop with chemical vapors such as carburetor cleaner, moth balls, muriatic acid, etc. it might be compromised.

Treat most any NOS or rebuilt item that has rubber, neoprene or leather parts as a core if it has been sitting on a shelf somewhere for an extended time.
