It is not accessible from below at all.....maybe if a tiny midget (sorry little person) and could climb up in there you might have a chance. I tried to pull the hoses off the fittings, but they were on their hard, I couldn't move them at all. I was concerned about breaking or torqueing the fitting so we gave up and went in from the top. Removal of the glareshield, Moritz cluster and CDI took about 15 minutes. Well worth the time to do it that way. The hoses still were inflexibly stuck onto fitting so just cut them off, they are only 4-5 years old and it is easy enough to replace when accessing from the top, I am saying easy now as we haven't replaced them yet. And in addition to hose removal their was an instrument bezel light hardwired into some harness going into bowels of plane.
For those who voiced concern about my mechanic, that isn't the issue. I just wanted a good starting point to approach the problem, I certainly understand there is a huge variety of airplanes represented here and if I could have saved some time by going from the top first I would have done that, I didn't, I think the responses above were leaning toward the bottom, that is incorrect. I am telling you no way could you have gotten this out from the bottom or side.
Will advise on reinstall if anybody wants to know.
