Fuel line(s) help!

I am changing my fuel lines to braided and when I fed the existing lines back through the wheel well the return line began leaking gas so I put the end in an old bottle I had and figured it would just drain the filter amount or something. I can't get it to quit running. I have half filled a one gallon jug and then I lifted it up in the air and tied it off until I can figure out what to do. How much gas should come out???? I can't unhook it underneath until it quits flowing.

Thanks for the help!!!!

how much gas is in the tank?

it will stop unless its siphoning out.

Not sure. I have the battery and everything unhooked but if I remember correctly should be about 1/2 tank. If it's siphoning any way to get it to quit without draining the tank???

blow air in it.........it will only keep siphoning if it keeps the flow, disturb the flow it will stop

thanks
