The pressure and return lines (power steering) on my 95 F-150 4.9 six were badly rusted and leaking. The pressure line was so bad I was able to push on it and break it off (at the compression fitting on the steering box)

What is the secret technique (or tool) used to turn those two compression type fittings? I've pulled off the driver side wheel, and tried getting a wrench on it through the wheel well opening, but can not move the wrench more than about 1/16 turn. The flare nut being a six sided thing makes it impossible to get any kind of torque on it.

Tried all kinds of wrenches from open end, to the proper flange fitting wrenches, lock wrenches and even bent a wrench end so it would clear blocking chassis, gear box and such. Still couldn't get enough swing to move the nut.

There is just not enough room to get a wrench on them. There MUST be some trick or some special type of wrench? Help !

 

Nope. The trick is to start with the one you can get at (the front, IIRC), and then do the other. Another trick is to bend the interfering tube GENTLY so you can get more movement on the wrench. It may also help to rotate or remove the fan shroud.

I know it's tempting to work thru the wheelwell, but I generally work thru the hood.

If yours really won't move, soak them with penetrating oil for a day or 2, and use flare-nut wrenches. If they still won't budge, cut/break the tubes off & use a 6-point socket.
