Re: venting portable gas tanks?
I'm wondering about this too. When the gas tank is not in use and I close the vent, pressure builds in the tank and causes gas to leak out from where the fuel line fitting meets the red plastic of the gas tank. This connection is tight and it's a brand new tank.
This is obviously solved by leaving the vent open, but I assume that gas is evaporating. I've tried keeping it in the shade but pressure still builds. This has caused my boat to fill with gas and oil. Do i have to worry about too much gas evaporating over the course of 1 week to 1 month that my boat may not be in use?
