I think I am picturing the hose your dealing with , a crowfoot with the right combination of ratchet , extension if needed and cheater pipe , if you don't have a crowfoot and have some old wrenches and a welding machine then you can cut a 1/2 drive socket in half and weld the square drive 1/2 part to a wrench right at the head of the wrench and cut off the rest of the wrench off and grind it down smooth , some tight spots you may even need to trim the ends of the wrench to get in a tight spot -------------- a couple of other methods which works sometimes is if you can get a long punch or chiesel with the point grinded down and put it on the hex of the hose fitting you can hammer it loose with shock waves , the shocking of it with some good Aero Kroil will most of the time get it to break free , on some I have grinded or sawed the hose off at the fitting and got a deep dish socket over the fitting and broke it that way , sometimes you can get a short wrench on the fitting and use a hammer or a pry bar aginst the wrench to move it , also have use a torch , perferablly the small butane plumber type and heated the fitting up some , the tool in the box is imagination
