I suggest get from Autozone the Delphi brand fuel pump for a 1969 or 1970 C10 with 350 engine. I got that one and it works well with my Quadrajet and I used it with gasohol with no problems for 2.5 years so far. I have a 1969 350 engine but the Quadrajet is from the mid 80's. My fuel pump also only has a fuel inlet and fuel outlet. It doesn't have that 3rd port you show in the picture of the fuel pump on the NAPA website. Where are you even going to connect that extra port on a 1968 truck? The fuel systems in the 1970 and earlier trucks were simple and didn't have vent lines that go to charcoal canisters, didn't have fuel return lines, and all that jazz. They just had a vented cap on the fuel tank, and a single fuel line to the pump and then to the carburetor, and that's it.
