Disconnected all of the fuel lines and blew them out with an air compressor. The line from the fuel pump to the carb was bone dry. Took the lid off of the fuel pump and the gasket is cracked. Took the plug out of the bottom of the gas tank and got a few drops...completely plugged. Dropped the fuel tank (busted one of the bolts) and found a hole in the top of it as well next to the sending unit.
I found out why the fuel gauge wasn't working.
Can of worms has been opened. Any input on the fuel tank? JB Weld the hole and get a new sending unit? New tank? Junkyard tank?
