Fuel pump replacement

[bbeberness]

Question??? My fuel pump sprung a leak around one of the electrical terminals so need to replace it and the filter.. My question is? Which of the 2 soft lines to a valve next to the pump is the one from the gas tank? I clamped the big one shut with a pair of vice grips but a lot of fuel still drains out. Do I need to clamp both of them and what is the other line? A return line?? Also I didnt get new copper crush washers, Should I replace these at the same time. Thanks in advance.
