How do I get it the line off. The freaking nut keeps turning the line and the second nut behind the line. I can't get anything small enough on the second nut to hold it. What are you guys using or are you cutting the line and recrimping it?
I used a 10mm but the second bolt keeps spinning. I think I found my problem with my alternator. In this pic you will see a red wire entering some black opening being held in by some red cap or something of that nature. I noticed my red wire was just hanging around and that red cap is totally missing.

Look at the two nuts. This is my problem. I turn one and the other turns also. I tried to get a needle nose plyer behind there, but can't get a good grip.
