At some point, every 2WD Vanagon will need to have the fuel tank re-sealed. If you are smelling gas after a fill-up or even see gas dripping on the ground, it's time for a tank re-seal! This is something that the average backyard mechanic can easily fix.

All vehicles made after or around 1974 have a fuel vapor control system. Before these systems were required, fuel tanks on vehicles were just allowed to vent raw fuel vapor into the atmosphere, which aggravated the smog problem. In the 70s, all filling stations in California—and then most in the rest of the country—were required to have those clumsy rubber boots added to the filling station pump handles. Those boots and the vapor control systems on all vehicles drastically reduced the raw gasoline that would usually just evaporate into the air.

Starting in 2008 in California (and undoubtedly coming soon to other states as well), a new law now requires that the fuel tank vapor control system pass a pressure test as part of the regular smog test. This kit contains all the parts needed to re-seal the part of the vapor control system on the fuel tank of your Vanagon. There are other parts of the system that may need service, like the vapor tanks, check valves, control valve, and charcoal canister—all of which GoWesty is familiar with and keeps in stock. But our experience is that the parts in this kit are all that is needed 90% of the time. Get ahead of the game! Be prepared!

To learn more, please read our detailed article on the problem in the GoWesty Library located here.

We also recommend installing the Hard Plastic Fuel Line Replacement Kit and the Fuel Line Replacement Kit at the same time—you’ll be glad you did!


Our kit includes custom GoWesty designed balance tube, fuel filler seal, transfer tube grommets, four feet of smooth German fuel line, and 16 stainless ear clamps (see required installation tool below) for a complete installation. Vapor tank grommets and valves not included (see "Notes" tab). We highly recommend replacing the fuel level sending unit at the same time. See related products below.


SPECIAL TOOL REQUIREMENT: Installation requires a pair of pincer pliers for the ear clamps. Sold separately below. Installation instructions NOT included.

Compare your filler neck with the image above, then use the drop down list to order the correct kit. REGARDLESS OF THE YEAR OF YOUR VEHICLE, PLEASE CHECK TO ENSURE WHICH TYPE OF FILLER NECK YOU HAVE.

Kit 139: 80-83 Vanagon aircooled & diesel with STEEL filler neck.  (+$10.00)
Kit 139A: 83-91 Vanagon watercooled with PLASTIC filler neck.

GoWesty does not include the grommets or vapor control valves at the top of the vapor tanks for the following reasons:

1) These are located at the top of the vapor tanks and are not subject to coming in contact with liquid fuel, just fuel vapor, therefore it really has nothing to do with the common 2WD fuel leaking issue for which this kit is designed to address.

2) The vent valve is made from a material that gets very brittle over time, making it almost impossible to remove either the hose from it, or it from the grommet and vapor tank without destroying the valve, so it is better left alone.

3) In order to get to these items, one has to remove the vapor tanks—which is an entirely separate job from re-sealing the fuel tank, and can be done at any time as a separate project, if/as needed so there is no duplication of effort.

4) The two hoses that connect at the bottom of the vapor tanks are subject to liquid fuel, and should be replaced, these are included in our kit as is everything else that is typically needed to fix the fuel leak issue in a 2WD Vanagon.

5) These two hoses can be replaced without removing the tanks. If you are having this kit installed professionally, the time and money saved by not removing the tanks/valves can be considerably high.

6) The tanks rarely go bad because, unlike the material that the valves are made of, the material the tanks are made of is much tougher.


We've noticed some of the competition making false claims about our crossover tube. Our design features the highest-quality fuel hose available - and this hose is much more durable than rigid plastic. We had the nylon t-fittings custom-manufactured for this application only. Our assembly is engineered in-house, tested in-house, and used in-house. It works, and it works well!
