Just tossing these into the mix. As I recently repaired (yesterday) the vapor system on my 89 Vanagon Westy, I found the plastic ball inside the tank. It had been pushed out or fallen out of the cage at the end of the filler tube.
I was able to reinstall it, but while doing so I pulled one out of an 84 parts Vanagon to compare the filler tubes.
Here is what I found fyi.
Without ball in the cage.

Upper is the later model filler with cage.

With ball reinserted into the cage. The cage had no tears and was very solid.

I just bought a filler tube but as everyone else has noticed, there was no ball with it. Believe it or not, I did a quick search on Amazon and found this: http://www.amazon.com/gp/product/B005GFT4O2/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1 These fit but looking at the picture posted previously maybe a little small. Sure you could find them in 1.25" though.

just have to make sure not to mix up the gas cup for the beer cups.. Exclamation

Ball float valve NLA. On the positive side, I'm building up a nice collection of worthless fuel filler necks.

I'm no chemist, but I'm thinking that dissolved ping pong ball might be bad for the fuel system. Very Happy

Does gas dissolve a ping pong ball? It is nitrocellulose.

Luckily, I had Guinness in the fridge. Tore up the can and tried it out on your advice--too small. I've got an email in to Van Cafe to see if the part is NLA or not.

Looks like the ball inside a can of Guinness. Wonder if that one is fuel-proof?

Thread resurrection...

I was out at a pull-it yard this afternoon (the one at US36 and Broadway) picking bits and pieces off of an '88 Wolfsburg. It was pretty picked over, but I was lucky enough to pull a good lower grill and a decent heater cover.

I pulled the filler neck just for kicks to see if I'd get lucky and find a ball float valve at the other end.

Well, the cage is there, but the ball is gone! D'oh!

The little cage has a part number, though, 191 201 207. I've checked a few of the usual sites and haven't had any luck yet.

Awesome. Anybody need an extra gas-vometing filler tube?

Don't waste your time. The float is externally mounted - very visible if present. If you don't see it, it's not there.

I have pics of both models - will edit the post when I get a chance.

Edit: ok, here are the pics:
251 201 129 (from my 87):

I almost answered "D'oh" to that, but now that I've seen the actual parts, well, that description is dead on Very Happy

I just got the part from a guy who was parting out a '90.

It looks identical to the one on my '85, part number 251 201 129, same as the old one. I'm thinking that if it doesn't have the "a" suffix, then it's probably doesn't have the ball float. I can't tell any difference between this one and the one I already have. Which sucks. I might just install and see if there's any difference.

Merci Perales.

Haven't tried the technique yet - van smells gas when full, so a reseal is in order, and full fill-ups are to be avoided in the meantime. But if I find the right part at the right price, I'll change it at the same time.

I've tried the nozzle technique but I've never been able to get it to work. Generally what I've always done is slow the gas flow down to a trickle as I'm estimating that the tank is almost full. That's the only way I've found to not have it splash out.

I found a used fill tube from a '90. I'll report back after I've installed and filled up.

The nozzle shutoff port is on the lower end of the tip. So, as it nears full, you have to lift the nozzle handle upward. This tilts the tip downward where it will be immersed in the liquid as the level comes up the filler. This technique works to make them shut off, but you can't walk away, you have to be there to hold up the nozzle at the end.

This has been discussed plenty around here, the old hands all know it already, I'm surprised no one has "filled" you all in!

Almost a mug shot Smile

BusDepot and Frank Condelli have the 251 201 129a part named earlier in the thread. But be sure to be seated before looking at the price...

Any part number you can share, and/or visual cues to recognize the right part ? Pictures would be great.

Thanks,

Hey, I just installed the later model filler neck and (at least after a couple fillups) it seems to have done the trick. No more burp. (The "technique" wasn't doing the trick.) I found it in the classifieds--just post a WTB and see what happens. Cheers.
