That's what I recall, it was a bit of a pain to get in there to tighten my winch bolts last time from what I remember. The problem with this location for me is I was considering putting in a front hitch receiver for moving trailers and whatnot with. I still may just put my compressor in the rear door.
I noticed the tubing going to the inlets for the cleaners. It looks like you're using clear vinyl tubing for that? If so I'd be careful if your running that clear to the air cleaner box, that stuff may collapse the moment you turn the compressor on, especially with that long of a run. It's hard enough to keep it from collapsing just at ambient air pressure, never mind under a small vacuum. I'd get the largest inside diameter compressed air hose you can find and use that instead, it will be far less prone to collapse. Running rigid pipe for most of the run would be best as well, some 1.5" or so inside the engine bay and the bumper with some flexible hose between the bumper and body would be good I think. With the long run it can choke the compressor a bit, so a larger diameter for most of the run will help it breath better.
