Re: rear gas tank issue

My truck will sit longer than that and of course it takes extra cranking to fire up, but once it gets the gas it fires right up. If I poured gas in the carb I am sure it would fire right up first time. Does the choke work properly? It's still chilly some here, I assume the same is true for Nebraska. One thing about the original gas tank is you have gravity on your side.
Could it be normal carburetor behavior vs fuel injection that most people are accustomed to these days? If the trucks never needed an electric fuel pump when they were made, I don't see why they should need one now.
agree , and if you have a quadrajet carb , they are famous for the 2 plugs at the bottom , cracking leaking fuel into the engine , drying the carb out , that would be my first suspect
