In 1980, I had to change my fuel pump alongside the road on a HOT August day out in the middle of New Mexico, my car also has AC and power steering. I accomplished it somehow with only a basic 3/8" tool set. I remember having problems but I got it done. Perhaps I pulled other things out of the way to get in there but I still remember how tough it was tough to get in to that one.
Necessity, The MOTHER of invention! (yes, I purposely emphasized the word MOTHER!)
