Is there enough slack in the hose to route it on downward arc and then upward arc,
so that you can open and close the engine deck lid without the hose 'pulling' and not relaxing. If so, safety glasses, cotton gloves, open end wrench, very carefully loosen the fitting nut on the compressor a few degrees, re-orientate the 90 degree fitting downward enough to so you can remove the oil filter, snug up the fitting nut.
And, if you wondered, yes, we did change the hose design years ago to a 90 degree fitting at the compressor and relocated the pressure switch on a T several inches toward the back.
