I have an aluminum tank I bought for my pontoon and it has a fitting for a vent and I want to put one in. Should I just put the vent at the hole or run it a ways from the tank for some reason? What do you suggest I buy for a vent piece. I saw some stainless ones tonight with just what looks like a 3/16" hole on the side of it and a barbed fitting to run to the tank. <br /><br />Any ideas or prior knowledge? <br /><br />Thanks... Gary
