1999 4100 scb holding tank vent filter

[arwelch475]

Hello fellow owners, I'm back again. As I've discovered that I have one of the boats where the waste inlet elbow was never properly tightened into the top of the tank, I figure while I'm at it I may as well replace all the hoses off the tank. Can anyone tell me the routing for the holding tank vent, and the location of the in line vent filter if there is one? Thanks , everyone has been great since we joined the forum. AW
