Well now, to answer my own question. 1.) I have figured out that there is only one fuel pump relay for both pumps/tanks ( it is the green on on the driver side fender wall ), 2.) There is no external selector valve that switches the tanks. 3.) The fuel pumps themselves have a check valve on the outlet side of the pump that delivers fuel to the engine. When the pump is energized by selecting the tank the pressure in the pump builds up behind the check valve and forces it to open allowing fuel to be pumped to the engine.
THERFORE. I have one of two problems. The lesser of the two evils is that my selector switch is pry bad and needs replaced. Or the greater evil, my fuel pump needs replaced because the outlet check valve is stuck shut. Which means I have to figure out where I'm going to stick 9 gallons of gas in order to drop the tank. Since I don't hear the fuel pump kick on when I try to use my front tank I am hopeing its the tank selector switch. I will post my findings.
