I am wondering if anyone has opened one up and taken a picture of the inside? Like this part from Tom's: Fuel Vapor Recovery Bottle. I am curious if it has any baffles inside or if it is just an open volume with no baffles, and if it has baffles then exactly how they're arranged.

1 have one not sure if baffled
, but if not then guessing the length of the tube into the reservoir for each line ,,the vapor lines from tank/s would go up inside nearly to top as well the line comes it out and going to canister.. and then ‘a liquid drag n back line then tank that jumps st goes inside at bottom of reservoir,,, fwiw that’s what I did with mine I made a reservoir out of stainless that fits up inside the cavity outside up in the fenderwell .. works well,,

If you were to look inside with a borescope, you would typically see that the outer lines have small plastic tubes extending toward the top of the tank, while the center line (drain) does not.

Thanks!
I don't have one of those parts to look at, but I figured that someone, somewhere had gotten curious about what they looked like inside.

Here's my 3 port (no auxiliary tank) fuel/vapor separator held in front of a light.
You can see the two outside ports have long tubes extending toward the top of
the bottle, whereas the center one doesn't. The left one goes to a charcoal canister
mounted to the firewall and the middle and right ones go to the fuel tank.
