My guess is you have a 67 or 68 with a single line from the tank you bought a fuel pump for a 69 350 because that was the first year for a 350 and that is what you are putting in the truck. You probably now have a pump with a return line which you do not need. You should buy a pump with no return line even though it is going on a 350 because you do not have a return line going to the original fuel tank. Then you will have the one port that should attach to the tank line with a 8" or so piece of rubber fuel line and the threaded fitting that you will thread the 5/16 steel line into that goes to the carb.
