Has anyone change the sanitation lines on a 4300 Sovran? Are the lines attached to the hull or other structure in any way that would prevent me from simply pulling the line out while replacing it? If they are attached are there access points to the fasteners? I have a vacuum leak in the hose and hope I don't have to cut holes in the cabin to replace the hose.
Thanks

Any time I have an odor problem I always look at the holding tank vent.  If the screen gets plugged the gas pressure can back up anywhere.  If there is a filter in the line it too could be blocked by over filling the tank. Change it out.

I  would look at the vent screen as they corrode shut and I would consider removing it as it is only required on fuel tanks. 

When you do a pump out do you hear a hissing sound in the vent area indicating a restriction.
