Trying to put fuel lines in my car. Tryed bending my own. 2 hrs later just through them away. Bought new ones. My car did not have any fuel lines or gas tank in when I bought it trying to restore it. Ran the main line and the return line to the fuel pump mechanical. I am confused because there are only two lines on the fuel pump I'm assuming one is for the main fuel line feed in the second goes up to the carburetor where does the return line hook to any help would be appreciated.
