Fuel Tank Lines?

[gbodyera]

So, the weather is pretty nice for the next few days and Ive decided to install my new electric fuel pump setup. I just dropped my tank. Which line is outlet and which is return line to the tank? Ive read that the bigger hose is most likely return but I think they are the same size! Who knows? Thanks in advance.

The main line is the line in the center of the float assembly. The return line should be located off-center. Replace the rubber lines while you have the tank down and use new clamps. If you are going efi, make sure the rubber hose is rated for fuel injection!
