Or the drain became plugged?

Not really - no real drain hole, but the cover is not air tight, and there is a gap in there from some corrosion. So, it's obviously not supposed to be "fuel proof". It does look just like the corrosion that builds up on battery terminals, and the housing for the fuel sender looks like the same type of pot metal as the battery materials. I'm planning on vacuuming this out today.
The overall plan is to fix the brakes (and perhaps suspension), and then put the wheels back on, put it in the trailer, and then take it back to work to place in our HUGE carport in the back parking lot. Then I will fill up the tanks with some type of volume of carburetor cleaner, and pump it through using a spare low pressure fuel pump (that I use for emptying tanks - I have a pre-made rig for this stuff) through a few filters (that reminds me, I need to order about 10-20 of these). Then re-evaluate the condition of the tanks. We'll do this outside under the carport - it's 30' x 20' so even if it happens to rain, it should be well protected from the elements.
That's the plan at least. I'm sure it's likely to change...
