All good questions. I am not sure how old the gas is. The previous owner drove the truck to my house in May. I have been starting it a couple of times a week since then but only driving it around the block since I did not have plates on it. It doesn't smell bad.
The lines are steel and look in good shape. There is a filter with a glass bowl and then a standard inline filter just before the carb. When the car would not start there was no gas in the filter near the carb but there was some in the glass bowl.
I will check the fuel pump and also the pickup in the tank.
The idea of a using a small gas tank is a good one in that it could tell me if the tank is the issue.
Thanks everyone for the ideas.
