Hi All,

I recently bought a 2000 396 and have been working on getting her back in order after a few years of neglect. Can anyone please tell me where the black tank vent filter for the forward head is located and how to access it? My newly established pump out service had been only pumping one tank…sadly, the wrong one, so it backed up in the vent.
The vent seems to be clear now, but it think the filter has been fouled. I would like to remove it, bridge the line, flush the vent, and install a replacement, but I can’t find it.
There is a wood platform on top of the forward black tank, and I fear underneath is where the filter may be found, but I am not sure because the origins of all the lines seem to be visible. So before I start what seems a difficult process of removing that platform, I would love for someone to advise.
Thanks so much.
