What size tool?

What size tool do I need to get the fuel lines off the fuel pump? I have been trying a 3/8 but it is not working.

Do not put a wrench on the fuel lines to the fuel pump. You need an air conditioning & fuel line removal kit like

Both lines are different sizes, you simply pop the tool over the line then slide with force into the connector releasing the duckbill type connector and the line seperates.
