Discovered after running out of fuel, fuel selector valve is not apparently working. Anyone have a good part number for a replacement.
Bad trip story to follow.
But, lesson learned - when help arrives from your road service to bring you more fuel - make sure BEFORE they put it in your fuel system that it is GASOLINE. Fuel delivery installed 5 gallons of diesel in my tank. Guess whose GMC did not make it home. Luckily, it was realized before attempting to start the engine.
In Pain.

I mean no disrespect, but I have a hard time understanding running out of
gasoline in a vehicle that holds 50 gallons of the stuff. GMC fuel system
instruments are not known to be the most reliable, but their odometers are
fairly accurate. Most of us average 50 miles per hour while traveling. If a
person starts a trip with full fuel tanks, and fills up every 4 hours or
so, you don't even need gages. You shouldn't spend that much time driving
at one stretch anyway. It is dangerous. Just speaking as one who drives on
the top half of his tanks. GMC's run better with lots of fuel in the tanks
anyway. Ask Gene Fisher.

The original is no longer available but there are plenty of work - alikes. You'll have to cobble up a mount. Have a look at:
http://www.gmcmhphotos.com/photos/cane-9-creek-rv-park-heflin-2c-al/p58463-fuel-pump-follies.html
That's a piece of flat steel I got from Tractor Supply and hacksawed to fit. The lines from the tanks and to the front are uncut and unchanged, just removed from the valve and connected as shown. You could place a selector where the pumps are, and won't need the relay. I wanted the electric pumps so I put them there. I kept the selector, capped. I also have a mechanical pump, and as you can see, the line from the rear is adapted into the original hardline to the carb. Thirty minutes and I am back to stock if I want.

When I replaced my fuel selector valve years ago (prior to eliminating it when I installed in-tank fuel pumps) I decided to mount it to the outside of the frame rail so as to make it easy to work on when I might have to when on a trip.
Nothing worse than lying next to the motorhome with your legs sticking out onto a narrow road with trucks whizzing by.
There is a gap above the frame rails in the area of the fuel tanks where you can stick the hoses that connect to the fuel selector valve without having to lengthen them or cut them. They connect to the selector valve. In front of the selector valve I connected a Mallory fuel filter with a shutoff valve connected to it. In front of the filter is my electric fuel pump and in front of that is a fuel pressure gauge sender. There is a steel 3/8” fuel line going along the frame to the front where it goes up and over to the back of the engine to my fuel injection system. Pictures are here: http://www.gmcmhphotos.com/photos/mallory-fuel-filter-outside-the-rail/p25709-outside-frame-large-fuel-filter.html
This setup makes it very easy to work on the components. The eyebolt standoffs are to let the parking brake cable clear everything.

Tom,
We were surprised when you disappeared from the site next to us at Ormond
Beach. And more surprised when we began hearing the feedback through John
R. of your situation(s). Glad you were able to make it home OK though.
Turned out, we only drove through a little rain this morning, with none
after we got on I-10. So your early departure may not have been necessary.
Re: Replacing the selector valve. Some are probably getting tired of
hearing it, but I consider it foolish to bother replacing the selector
valve. It costs little more, is little more work, and yields desirable
redundancy when one replaces the selector valve with two electric fuel
pumps, one for each tank. I've run that way for probably 15 years. Two
Carter 4070 pumps each feed a tee through Viton sealed check valves. The
output of the tee is attached to the metal fuel line forward. I also
recommend bypassing the mechanical pump as unnecessary and possibly
hazardous to the engine. The check valves are not really necessary with
the pumps I use, but it's possible I could be forced to replace one of them
on the road with a pump which did need them; having them in place seems to
have no down side.
We'll talk in the next day or two; I need to give you John Beaver's number.

I have heard of that happening on airplanes. Jet-A instead of gasoline put in the tanks. Different size fuel nozzles and different color gas cans were suppose to take care of the problem. When someone puts the wrong stuff in the gas can there is not much you can say. My diesel cans are yellow while my gas cans are red. My kerosene can is blue.
It is just like Canadian money. They ought to be able to tell the difference even if they can not read.

Thanks for the helpful answers. Parts book is in coach, about 250 miles from here. Not too reachable. Refueled coach with 25 gallons before coach ran out about 6 miles from next fueling point. I expected that I started with 40+ gallons, and did not anticipate this problem. Discovered that fuel selector valve did not function the hard way.
Diesel is being removed at Good Sam's expense. Then, I can start own "what the heck is wrong road?". I have started by replacing the fuel filter in the carb. If fuel will flow, then I'll get it home and chase the rest of the problem.
I expect the final solution may be twin fuel pumps, ala Ken's suggestion.

Those valves can fail in a mode where both inlets are open. When that happens, it will suck air from the tank that is low and never get the fuel out of the tank that still has gas in it.
