[lamans71]

I am wondering if anyone has a fuel line diagram for a '71 LeMans. Here is a photo of the tank I removed, obviously the one I circled in red is the supply line but are the other three all vent lines. Or is one a return line (return from the charcoal canister?) and then two vent lines? And which is which. I can see the supply line running up the driver side frame and a line from the canister running down to the passenger side frame rail. Just hoping that someone has the knowledge or a diagram rather than crawling under and hand tracing the lines.
