Accidently left the fuel hose on top of the carburetor and gas poured into the carburetor, will not start

There other day I broke down in the middle of the road after I gassed it to get around someone. My trucked made the pass then sputtered and shut off. I was not able to get it to crank back up and drained the battery trying to do so. So my son comes to help me at least tow it off to the side of the road and there we tinker around and find the problem. We disconnect the fuel line from the carburetor (yes, I took the tbi off and replaced it with a nice 2 barrel Holley) and he had me turn on the ignition and no fuel, so now we know it's the fuel pump. So, fast forward about two hours and we got my truck hooked up to chains behind his truck ready to pull me home. About half way the chains come unhooked and we pull to the side of the road were we noticed gas just pouring out from the bottom of my truck. I snapped and ran and turned off my ignition. Seems that during the tow the fuel pump decided to work after all. Unfortunately we had left the fuel hose just hanging inside the top of the carburetor. Next morning first thing I change my oil, which is now about 5 quarts oil and 5 quarts gas, and try to crank it up but the starter just goes boom like it's stuck. We were able to manually turn fly wheel as well as make all the pulleys under the belt turn. Not sure what is wrong or what actions I need to take next. Please help.
