first off don't use an open-end wrench or you are sure to round the heads off. I have a set of "line wrenches" that I use. They are open just enough to slip over the line but act as a
boxed-end wrench when you try to loosen something and won't round the heads off..unless very very tight.

I would spray some "kroil" or PB Blaster on them and then let them set overnight. Then spray some more on it and afer about 5 minutes put the line wrench on it. First try to TIGHTEN it just a bit and then loosen it.
If this don't work then get out the vice grips and get mean with it!!!

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
