I once did this with a cheap solid state electric pump mounted behind the front frame rail and a
switch under the dash. (I had a big problem with what I thought was vapor lock.) Though this didn't
seem to help my vapor lock issue, it did not seem to negatively affect the operation of the normal fuel
pump even when off.
All of my Corvairs now run mechanical pumps only... but I've replaced mechanical with electrical
pumps in several of my British cars and the starting after sitting several days is much improved.
