It's a pain. I just did one on a coworkers. With the 4.6 at least you can view end of the hose near rack connection from the top 13/16th on female and 11/16th for hose end. There was a slot in the frame on his 97 cougar that I could get my wrench in between. Got decent swing flipping wrench around every time.
Be waaayyy easier if you have a way to lift the engine out of the way a few inches.
A second hand to hold the wrench on the top is helpful aswell, but you can wedge it decently.
