disconnecting lower intake fuel fitting help...

I cant seem to get the freaking things unhooked.

The tools I have (came in a pack of 6, but I could only find pics of 2) look like the ones at the very top of the page, beside the google icon

fuel tool

Are these what I need to get off the fuel lines along the lower intake??? I have the upper off, and everything disconnected but the fuel lines, I cant seem to figure them out. Any advice on how to properly use these freaking things, or do I have the wrong tools...

Thanks guys

Thanks guys, Im hoping to finally get them off tomorrow am. Its been raining most of the day here, and now Im at work... finally getting ready to go home :bannana:
I yanked and yanked on the things yesterday afternoon. I dont have a prybar, any ideas on what else I could use to pry the thing off with. Ive left the distributor on, so that limits how much room I have to play with under the hood. All thats left for me to bolt on the new Cobra upper and lower is those 2 freaking fuel fittings, and the bolts on the lower intake. Everything else is off and waiting.
Just to make sure. Im using a 1/2" tool on one line, and a 5/8" tool on the other. Do these sound right to you guys who have done the swap recently???

Thanks again, and heres to getting the freaking things off tomorrow
