Tank vents

[KWKloeber]

Vent hoses and stanchion hose barbs don't cause lesks, PEOPLE cause them!!

The deck thru-hole simply reveals you have a problem that could have been avoided!

[Ron Hill]

Guys : If you want to change the vent to other than the stanchion here's wat I'd do :

Take the vented stanchion and replace it or
saw of the portion is the stanchion that goes thru the deck!!

Then fill in the hole in the deck with epoxy
You then can bed in (with butyl rubber)the old modified stanchion, but you'll still have the helpers on the deck fending off so you best add a backing plate!!!
