I am believer that you can switch whenever you want. I think that keeps the fuel selector working. You don't use it for a while, your fuel selector valve gets sticky.
when I had a carb and an electric pump on the aux side, everytime I started the coach, I switched to Aux, hear the pump run a little. fire engine then switch to main. Usually kept it on main unless I had experience of vapor lock or thought I had potential for vapor lock.
now that I run 100% electric pumps, 2ea, 1 for each tank on my EFI system. I still switch between the two, in belief that the more you use them, the better they are.
almost every GMC I come across, no two are the same anymore. different routing of lines and vents. Different fuel pumps and wiring. many different places people stick fuel filters in. If they are the same, it is because it has 45 year old parts that are gunked up from non use.
now what Every GMC'r should take some time and study this slide, so they understand what hills and fuel can do in the GMC:
