whooshing sound when removing gas cap

That is not normal, there is a vent valve to compensate for that.

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 hear no whooshing sounds and I always do three topoff click-thunks --
even then I don't approach spillage level.

You need only three tools: WD-40, duct tape and a hammer. If it doesn't
move and it should, use WD-40. If it moves and shouldn't, use duct tape.
If you can't fix it with a hammer you've got an electrical problem.

On anything newer than 2000 that is a good way to wipe out the charcoal
canister. Fuel goes down the vent line attached to the side of the fill
pipe and drowns the canister.

How far from the top is the vent line attached? LA County filler tube, BTW.

Most are just below the flapper valve in the filler neck.

From what I read, that closes when fuel gets high enough in the neck,
right? 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.

^This!!^ Why I haven't topped off in fifteen years!

Of course, you might as well be explaining it
to a wall - present "Real" company notwithstanding.

No the flap I'm talking about is the one the fuel fill nozzle opens just
below the cap. 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.

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.

Given my sinful triple-top-up procedure, I've observed that different
pumps have different levels of stoppage. Is there an actual standard?
