'97 7.3 possible bad tank selector?

Today I switched to the back tank for the first time in several months. Truck ran great for a 40 mile trip. At the destination I let it sit and idle for a few minutes and shortly after it started shuddering like it was running out of fuel. Thinking I had some bad fuel in the back, I hit the selector switch to try and get it to suck through the front before it died and noticed the gauge didn't respond (there was between 1/2 and 3/4 in the back and just above 1/4 in the front so it definitely should have moved). Revved it up until the engine slowly lost power and died. Cranked several times to no avail even though it acted like it was trying to start. Let the engine cool off then opened up the fuel bowl and it was dry. With it still switched on the front tank (but still showing the back tank reading), I tried starting it again and after a while cranking it caught and I gave it some gas then it idled smooth for several minutes before turning into a rough idle as before and dying again. No fuel again.

A while back I replaced a couple of the under dash fuses with resetable breakers and when I checked the selector valve/AC breaker it was tripped. I reset it, turned the key on with the A/C harness completely disconnected from the system and it tripped again after a few seconds.

At this point I'm certain it's the valve. I'm stranded away from home and this is my only vehicle but luckily there's a NAPA near where I'm stuck and I've already arranged to go pick up a new valve once I can arrange transportation to get it. Can anyone else shed some light on this?
