on my 47 with hydro vac, how do you guys bleed the hydro vac? man that thing is hard to git too and see. I did it about 6 years ago, but I had the sheet metal off and now I dont. I could reach it but not easy and I could not see it to bleed, have to go by feel. Looks to me like I would have to take my sheet metal off again to do a good job - able to see what I am doing.
