Fuel Line Routing

    I hope this question goes here. I am swapping frames on my 17 Skylark and am trying to figure out the correct routing for the fuel lines. The car is no help cause it's a NY car and the lines have been replaced too many times to help. Does anyone have a diagram that shows how they route.
    Also, one last question that I think I have the answer but want confirmation. My car only has a fuel line and it has an electric fuel pump, That, to me doesn't seem very safe. I am considering adding a return line, is it as easy as changing the sending unit and routing the return line?

    Here's the fuel and brake line routing on a bare 1970 GS455 frame before the body goes back on. It also has a return line. I don't know how, if at all, the '71 lines might differ. Not sure if your electric fuel pump requires a return line or not but it wouldn't hurt to install one if you have the frame that accessible. Someone else will know.

    Thank you, those pics are a great help. I have the body off the frame right now, now's the best time to do it.
