I need to replace my head storage tank pump out hose. I’m not quite sure how to get access to the connection below the deck plate. There is a small curved liner piece in this area. It looks like I might be able to remove this piece if I work its bedding loose, but I don’t want to attack it without some confirmation that I’m on the right path. Any advice?

Thanks

Mike,
Using pictures from Bob Goldman on Xanadu, last winter I replaced all the sanitary hoses “downstream” of the holding tank i.e. to the macerator pump and to that pump out fitting. I used pvc in lieu of the flexible hoses. The change is spectacular resulting in total elimination of any odor. To make that connection you are asking about I cut the existing hose a few inches below the deck fitting within the
