HELP! Fuel Return / Fuel Supply Line help

[Cruiser Innovations]

I realized that there was a small fuel leak coming out of one of the two rubber fuel lines that run to the Carb supply / return hard lines... After looking at a few graphs it looks like the lines have been crossed.

Is there a difference in the internal pluming of the tank where the Fuel supply / return lines connects? If not than I won't worry about it but if there is I would like to make sure the Fuel supply line and the fuel return line is hooked up to the right nipples on the tank...

I have a 74' FJ55 if that helps..

I do not know how the inside of the tank is plumbed. I do know that I have the original intact hardline from my fuelpump to the carb...it goes in the lower of the two banjoes. The one that points to the valvecover. The return line is on top and points to the radiator. Also a '74 Pig.

when I had issues years ago with an early 70's? there is a difference in the tank plumbing. I ended up disconnecting both lines and sticking a wire into both tubes, 1 seemed to go in just alittle and the other seemed to go in much further and seemed to bend to thebottom of the tank. I also checked by blowing into each tube and could hear bubbles in 1 and the other just blew thru.
