Hi guys can someone please point me in the right direction, I don’t know which lines are which, I need to know what line is the fuel delivery line and what line is the return line, Also there’s a line with a weird crimp in it, Thank You

 

I assume this is a 1970 with the evap cannister? The two lines that go through the front crossmember are main fuel line (large one) and fuel return (small one). The other line goes to the evap cannister. The "weird crimp" is the restriction in the evap line to prevent liquid from being pulled out. You are missing the vapor separator that bolts to the bottom of the floor pan. And the PIM is your friend. All of this is shown in Section 8.

Trivia point: note that this diagram says "exc. W27". There is a slight difference in hose routing on W27 cars to clear the cover.

 

Joe thank you very much!! As all ways you’re the best!!
