HELP, I'm about to really mess up!

["John L. Rahn" <john_rahn@xxxx>]

HELP!!! I'm trying to remove the old fuel lines that run from the 
fuel pump to the metal lines on the frame. The metal fittings that 
join the rubber coated lines to the metal lines are driving me 
crazy. I finally got one off but the other is really on there. I 
heard that if I damage the metal line I will have to remove the body 
to replace it so now I'm scared to death to put too much pressure on 
it to break the joint. One fitting is 17mm and the other is 14mm. 
I've tried liquid wrench and other penetrates to no avail. I'm 
thinking about trying to somehow soak the fitting in really hot water 
hoping that might expand the metal enough to break the joint. I'm 
able to get flared metric wrenches on the fittings but when I put a 
lot of pressure on the wrenches to try and break the joint, the metal 
hose starts taking a lot of stress. I'm afraid I'll damage it if I 
keep twisting it. The one I removed was very clean with no rust. I 
can't understand why the other one is so tight! Guess I should have 
left well enough alone...

ANY help will be greatly appreciated.
