I got a filler tube from a junkyard years ago I think it was a 70's Galaxie wagon. No it's not vented and car runs fine bur cap hisses a lot when opening.
I am in the process of venting it , waiting for a check valve and will connect it from filler tube to back panel where factory pop-open cap is
pop-open cap is.
