To remove the lines you need a "special" tool, or make your own like most on here do. I took a 1/2" wrench and ground the open end down to a point at the ends, and up to 1/8th" at where the handle meets the open end, that gives you a nice gradual bevel. You carefully wedge your "tool" in between the QD halves on the line, and as you insert it, you wanna start to push-pull the line, til you evnetually have the tool inserted a good ways and the line will pop off, may take some force so don't get too discouraged.

I just use two flat screwdrivers. A little cumbersome, but it's not worth the effort/expense in my case for a special tool.

I also used screwdrivers. Took me about 10 seconds to pop each line off.
