Valley,
In our community see have seen a lot of fuel system troubles and have a pretty good set of solutions.
There is a good chance that there was once an engine driven fuel pump. It was probably removed when the ethanol killed it. There was probably also a tank selector valve. The rubber in the fuel system is probably all shot, but even if the alcohol didn't get it, it still would have aged out by now.
The electric pumps (one per tank is a common solution too. The pumps close to the tank are part of a vapor lock cure. New "motorfuel" now has to be in spec with a much lower Reid Vapor Pressure to allow for the included corn whiskey that has to make lower.
So, add another pump and maybe a filter or two some wiring to control them and replace all the line with "Barrier Hose" that is as good as you can get with alcohol. We find this works pretty well.
