whooshing sound when removing gas cap
That is not normal, there is a vent valve to compensate for that.

whooshing sound when removing gas cap
What has not been breached here - and should have been long
ago - is if the owner was in the habit of topping off when gassing up at the station: 'click-thunk', 'click-thunk'. That action could contribute to his 'whooshing' experience. |

I would assume that it's located to prevent overflow... What actually makes the nozzle shut off? Upon occasion I've put in at least another gallon after the first automatic click-thunk shutoff. I like to fill it as full as possible -- you never can tell when you'll just be able to make it to the Mesquite station on fumes because it was too hard to find a cheap gas station in Vegas. -- Cheers, Bev "To liberals, building a wall across the Mexican border is a violation of the Voting Rights Act." -- Ann Coulter |

That stays open while filling to allow vapor to pass the pump nozzle. It acts as a valve to keep debris out as well as a restriction to keep people from using the wrong pump to fill the tank (diesel usually has a larger nozzle diameter that won't fit) Plus it helps prevent the fuel from pouring out at the instant the nozzle trips off. The nozzle shuts off when it detects a change in vacuum inside the handle. If you look inside a nozzle you will see a small hole or tube inside. While filling the gas flow over the hole/tube creates a vacuum. While gas is flowing that vacuum doesn't do much. However as soon as the tank is full the gas backs up in the fill neck. That blocks the tube/hole and the instant lack of vacuum trips a small diaphragm inside the filler handle which stops the fuel. -- Steve W. |

I first saw those when unleaded became the only option (remember smog heads?) and thought it was just to restrict the size of the nozzle that could be inserted. > The nozzle shuts off when it detects a change in vacuum inside the > handle.

Given my sinful triple-top-up procedure, I've observed that different pumps have different levels of stoppage.
