Re: How does a gas tank vent?

The "vent" is not there to let the pressure out....it allows air to come in to fill the space when the fuel is drawn out by the fuel pump. If it didn't, you would soon have a vacuum inside the tank. Once the vacuum level inside the tank got above the fuel pump's ability to pull......ya got nothin'. The engine won't run, or you have crushed the tank.

Bad planning on your part does not necessarily constitute an instant emergency on my part....

The great thing about being a pessimist is that you are either pleasantly surprised or right.
