Hello!
I am trying to figure out how to vent a diesel day tank for my new diesel cabin heater. The tank is mounted inside the on a bulkhead on the beam of this Catalina 30 (see attached photo) and will be filled via transfer pump from the main tank. I am not familiar with thru-deck hardware, spillage concerns when heeling over, etc. I can only imagine that venting to the cabin will make the cabin smell like diesel.
I know that the water tank vent goes through the deck up into a stanchion which has a hole drilled into the side. Seems like running a tee into that vent potentially exposes the water tank to diesel overflow. There is another stanchion next to the spot where I want to mount the tank - should I drill a hole and vent the tank there? Or should I run the vent along the top of the cabin all the way back to the main diesel tank vent on the transom? Or is there some vent I device can buy that I can install right through the deck that won't let water in?
Concerning heel: I am surprised that sea water does not enter my fresh water vent mounted into the stanchion at full heel.
What considerations I should make for venting a day tank?
Thanks!
