"I wonder" is correct.
I look to what is done for anything that wears like the carburetor throttle valve, rocker arms on the rocker arm assembly, king pins on a straight axle or an engine crankshaft. Consider the process to appraise what is typically done. Consider the search for repair parts. Factor in any machining costs. Also I consider the option of paying a professional to do it for me. All this happens in a couple of minutes (my mind is slowing down as I get older).
In the end, I gave more weight towards reliability, less hassle and cost over appearance (restoring old pump). I bought a new pump (a Carter Clone) from my FLAPS. So far I have enjoyed 5 years of no fuel related issues, doesn't leak and I have a peace of mind. Allows me to spend more time on other aggravating issues that need fixing.
