Alright... I'm on my second day of trying to get his stupid thing off my 98 Tahoe, and I'm getting frustrated. I know I waited too long, it's been about 18 mo. since it was replaced last. It was last serviced by a dealership down in SC when my fuel pump went out while on vacation. I think they may have overtightened it, but the flare nuts on both ends are obviously gettting more corroded with age also. If I ever do get this off, I know I'll be putting some anti-seize on the threads!

I was able to loosen the rear fitting, but can't get the other to budge. I have been soaking it good with Kroil and PB Blaster penatrating oil for the last two days. I am only using a flare nut wrench so far, but it is dangerously close to rounding off the hex. I hate to use a vise grip or some other locking pliers, because that usually destroys the nut. Any other tip or suggestions for stubborn flare fittings? Please don't say "use the torch" because I am probably mad enough to do it!
