The 55-56 tanks have nothing in the vent line except a path for air. Unless something managed to get in that small tube from the top or sloshing compound from the bottom or perhaps the short piece of rubber hose in the middle developed a problem and kinked or collapsed, I would more suspect something with the filling station nozzle. Did they change brands or type recently. Some of the nozzles seem more temperamental than others.

You might try lifting the rubber bellows slightly to provide an air escape. I know it defeats the purpose of the vapor reclaiming but I have to do that when filling gas cans.

You can remove the vent hose and check the tubing from each side and also make sure the hose is collapsed or swollen shut.

Replace it with a new hose, which should be friendlier with today's fuels.

Got the tank out and the vent hose is as clean as a new whistle-I replaced it 2 years ago? I flushed a good deal of black crud out of the tank and there is clearly a restrictor in the filler neck as I can fill the tank much faster via the vent tube but the garden hose backs up in the filler tube.
Given the curve of the neck, it would be difficult to force it clear with some tool, still thinking here.
I am certain that Fred would be happy to dust off a repro tank for me... At this point, some new owner is going to get a bunch
more free stuff.

Maybe a piece of welding wire can help to dislodge whatever is down there.

I can't remember if there is a baffle/flapper on the tank side of the filler neck. If there is, maybe it's stuck in the "closed" position.

The tank was no bloody good as is so desperate times lead to desperate measures. What we have is the attempt by an untrained wiper of people's bottoms to seal the gas tank and what happens when the material is exposed to fuel.
SIGH. Just living the dream...

A picture really is worth a thousand words!

Is that the vent tube or the fill tube?

This is why I have never trusted "Pour-In" sealers.

Get a repro tank from Kanter or get it Renu'd.

The Renu process media blasts the tank inside and out and then bakes on a coating inside and out. Comes with a lifetime warranty.
