Nope. All lines are good. The key was 2 days of PB blaster. I'd say I did 10 solid applications.

maybe if you run across something like this again try out the CRC line of products...that freeze off is suppose to work great on this type of application

This thread inspired me to crawl under m 97 C1500 work truck with the original fuel filter in it yet. I went to the local auto store today, got a new filter and armed with only a 20mm open end wrench and a 16mm open end wrench I proceeded to attempt to remove my lines. My filter and fittings were much worse than shown above and with a little force everything still came loose. No lubricants or fancy wrenches of any kind. However one of my fittings are frozen to the fuel line so I had to undo and move one of the lines, then spin the filter off of it that way Put my new filter on and couldn't tell a damn bit of difference. Oh well, it was 120K miles and 12 years on the original filter, we'll do the same for the 2nd one
