Fuel tank return lines

I had a fuel canister and return lines on my 70 Nova which I removed to clean up the engine compartment when I installed a BB. My question is, at the fuel tank there is a mulitude of lines comming out of the sender area, what do I do with these? Just plug them all except the one going to the fuel pump? Thanks for your input. Come on guys, someone must have got rid of the fuel canister, what did you do with the return lines at the tank???????? HELP????????????

lol, use whatever line was going to the pump in the first place, if you dont know put some gas in the tank and see which one fuel flows freely out of, oh and please make sure to upgrade the fuel lines, the stock ones are too small for a bb, go with 1/2. you dont need a return line.
