Hi All:

I have some gas smell in my garage after I park the car. I don't see any gas leaking and thought it might be the gas cap gasket or charcoal canister or lines to the canister. The injector seem fine. The car is a 1974 2.0 L.

Two questions: Any recommendations where I can source a NOS or high quality charcoal canister and required lines ?

Am I missing something as to the gas smell?

Thanks!

if you really want to there was a thread on the bird about how to rebuild one.

Never heard of The Bird. Can you give me more info or a link?

Thanks!

I had similar smell. There is a gasket under the fuel filler neck and a gasket under the sending unit that I replaced (you can get these rubber gaskets from 914rubber.com). These seems to fix the smell for me.

As referenced, there is an article on how to refill the cannister (get activated charcoal from a local pet store.)

Also note that I replaced every single vacuum line up there (and in the engine bay).

Finally, if you still have smell, you may have a leak underneath at the fuel lines and/or you may have a pinhole leak in the tank itself. For example on the pinhole leak, if the hole was halfway up the tank and you would smell gas more readily after filling up..

Excellent thread.

Thanks folks. All good info.

Does anyone know where to source NOS or aftermarket charcoal canisters?

I didn't think they were made anymore? You could check a local VW Parts shop. Or put up a WTB in the classifieds. Part# is 113 201 813B I think.

Otherwise, if you can get a hold of some activated charcoal (about 2lbs) from a pet store (or amazon), you can do the replenishing job yourself in about 30 minutes.

Here's a nice used one for $75 if you have money burning a hole in your pocket.

Here is another:

Note the second one is from earlier years. It is much more difficult to refill because you have to drill holes. The first one you can simply take apart (carefully).

Hmmmm....maybe they are still made?

Hi Bixterfan:

Yes, I saw those on EBay but figured they are spent by now. I am considering rebuilding my current fliter but wanted to "put it out there" first for a NOS or good aftermarket source in case someone had one.

Thanks!

If you redo yours, get the charcoal in the pellet type. Not the aquarium chunk. When I bought some sourced thru Amazon it was pretty cheap.

74 was a transition year; the earlier 74s had the two vacuum lines running along the driver's side rocker and the canister was on top of the fuel tank, while the later ones had the single small line through the center tunnel and the canister was in the engine bay.

Double-check which you have; it would be easiest to put the system back to how it originally was.

Thanks Dave. My car was manufactured 10/73 (it's a 1974) and the plastic canister is in the frunk in front of the driver, not on top of the fuel tank. It has 2 lines on one end, 1 on the other.
Part #113 201 823A on one side, #113 201 813 on the otger.

Here is link to charcoal pellets. This bag is just the right size.

That said, I doubt this is source of fuel smell. Probably time to pull the tank / replace lines and hoses.

That be the product.

Thanks Amphicar! I'll get some.
What part of PA are you from? I grew up in Pgh.

If you're saying that it is in front of the bulkhead and is in the trunk proper, it has been moved. It should be on top of the tank. Here is a pic of the early-style location:



You can see it between the fuel tank's evap chamber and the brake fluid reservoir. Black with a silver band around it.

No Dave, my mistake. It IS on top of the gas tank exactly where yous is located in the picture. Sorry.
Ron

Great post and great info. Thanks!!!!

Great thread and question: suggestions on how to open the early (1970) metal canisters so that you can recharge them, without destroying the canister?

The Bird is Pelican Parts http://www.pelicanparts.com/ They have a bunch of forums and tech articles for German Brands

This has been a very informative thread. Thanks to all of the contributors. Putting this chore on my "to do" list.
