Dave. Kaseler SLY 1975 C&C 33 Dave, One of the most important things you can do with this install is insure proper hose diameter for ventilation. Most head odor problems can be traced to vent hoses that are too small. If you find or have a tank made, put in the largest vent hose size you can fit. Howard Paul, Skipper of Knot Again, 35-3
