Has anyone replaced the hose that goes from the holding tank to the deck pump out fitting? I can not remove it on deck because the hose clamps will not fit out the deck cut out. It is run through the aft head which looks like I will have to cut an access hole in the curved fiberglass to get the hose clamps off. Any ideas?
I ran into the exact same problem on my 40.5
I was trying to replace all of the head hose, which is when I found the issue you are describing
What happened is that hunter mounted the pump out fitting & hose to the deck, and then joined the deck to hull, lowering the pump out hose where the mascerator is located.
I'm going a bit by memory here, but I think this is how I solved it
I seem to recall that I loosened the fitting from the deck with the hose attached
Then, I was able to spin the unit around.
I think I used a socket on the end of a flexible (spring type) socket driver. I was able to get the socket onto the hose clamp, even though reaching behind the panel was a huge pain
Be sure to disconnect your shore power first.
Once you get the hose clamp loose, slip it down the hose, and the deck fitting comes out.
When you replace the hose, you have 2 choices:
Modify the deck to clear the hose clamps
Or, buy a "clamptite" tool, which allows you to use stainless wire instead of hose clamps. I think that's what I did, but can't fully remember
