I've not removed mine on my C7, but I know on my 2009 Pontiac G8 GT, it required a fuel quick disconnect tool to release it. So I suspect that the C7 may require a similar tool.
i think there is an internal clip that a special tool is needed for. It is a split tool that wraps around the line and releases an internal clip. They sell them at most auto stores.

Harley - I just did mine a couple of months ago.
You need a special tool to disconnect the braided high pressure line.
I had a friend who is a 'real' mechanic stop by the house with the magic tool and popped it off in about 2 seconds.
It's next to impossible to get it off without the tool.
They sell the tool at most auto supply places from about $10 up.
Once you get it off though, you don't need it to put it back on, so try to borrow one or do like I did and find a good friend!
Help, Please
