I smell gas after filling up my Vanagon – is this the right kit to fix it?

Yes, this Fuel Tank Reseal Kit is specifically designed to address fuel leaks in 2WD Vanagons. If you smell gas after filling your tank, or even see fuel dripping, it's a strong indicator that your fuel tank needs resealing. This kit contains the essential components to fix the most common leak points, and many owners find it's a straightforward repair they can do themselves.

Will this kit fit my Vanagon? How do I know which one to order?

This kit fits most 2WD Vanagons from 1980-1991. However, there are two different kits to choose from, depending on your filler neck type (steel or plastic). Before ordering, carefully compare your Vanagon's filler neck to the images on the product page and use the dropdown menu to select the correct kit. Kit 139 is for steel filler necks (commonly found on aircooled and diesel models from '80-'83), and Kit 139A is for plastic filler necks (typically watercooled '83-'91).

Does this kit come with instructions? Is it hard to install?

This kit *does not* include installation instructions. However, the fuel tank reseal is considered a repair that the average backyard mechanic can handle. We recommend thorough research prior to beginning the repair. The kit includes the parts that are typically needed to fix the fuel leak issue, including the balance tube, filler neck seal, transfer tube grommets, O-ring for fuel sender and more! Be sure to have the right tools on hand, including a pincer plier for the stainless steel ear clamps, before starting.

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! Luckily, this is something that the average backyard mechanic can easily fix. Installation instructions NOT included.

Our kit includes:
• (1) Filler Neck Seal - Durogreen (Plastic Neck Only)
• (1) Vent Tube Assembly
• (3) Vent Tube Grommets - Durogreen
• (1) O-Ring for Fuel Sender
• (4) Tank Strap Pads - Durogreen
• Smooth German Fuel Line
• Stainless Ear Clamps (requires pincer pliers for installation)

Note: Vapor Tank Grommets and Float Valves not included in this kit (please see "Additional Info" tab for our reasoning).

Other parts to replace at the same time:
• Fuel Level Sending Unit
• Hard Plastic Fuel Line Replacement Kit
• Fuel Hose Replacement Kit

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.

GoWesty does not include the grommets or vapor control float 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.

No More Leaks!

The night I got my Westy I headed straight to the gas station to fill her up for the drive back to the coast. Once it hit the full zone of the tank gas started leaking everywhere. As soon as I got down the road a bit it stopped but I haven't filled it to the top for 6 years because of the leak. I just installed a new tank and vent kit and NO MORE LEAKS!

Fit perfectamd and it has everything that you really need.

Nice kit. Update: after a few fill ups, the 3 vent grommets on the tank began to leak. Purchased another set from a different vendor and the ID was noticeably smaller. Never had an issue with GW before and will continue to use them

as advertised

I had to get this because of a failed OEM part. A pain to install but I am happy I got it taken care of

Everything you need.

Has all the parts you need. Honestly using regular hose clamps would probably be easier, but those clamps work well. I put a little white lithium grease on the grommets and seals, helps them go in easier and should help keep the from drying out, also holds the o-ring in place if you’re doing the fuel level sending unit. I had to get get some extra fuel line because I needed to replace the lines going to the fuel evap tanks, but if you’re just doing the fuel tank it’s plenty.

Tank seal kit

Fast delivery, quality product and exact fit. Highly recommend.

Do this!!

Just knowing all my fuel tank lines have been changed, makes me more confident!

The right parts make it easier

Dropping your tank is a bit of a PITA, but installing these parts is easy. Always nice to know you have everything for the job before you get going on it.

Watch the video

This was not a terribly difficult repair but watching the video made it much easier. The kit worked great.

A CA requirement to pass CA Smog Check

The first reseal kit lasted about 6 yrs. Unfortunately, the Balance tube fitting cracked and caused a vapor/fuel leak. It might have been my fault during installation - i remembered struggling with it. Anyways, I installed the new kit and passed the Smog Check Evap Test with no issues.

Thank you

Great Fuel Tank reseal Kit

I used this when I replaced my fuel tank last year it has everything you need to do the job the right way.

No more fumes

Quick, easy install, and no more fuel smell

Seal er up

Vent cross over tube was almost impossible to install on my air cooled model. I had to add a 1/2” extender to it.

Power Steering Lines lead to this ...

I had not intended to have to replace the lines, but, when I saw I needed to, This kit was the logical thing to do with the gas tank out. Worked beautifully.

If you smell gas

When you fill up if you smell gas your tank could be leaking. Everything fit well, just make sure you get a good set of crimp pliers for the clamps.

As expected

Great GW quality replacement.

Great fit

This fixes a lot of common leaks.

Fuel tank reseal kit

Received the kit in record time with everything included.

Tanks for the memories

Everything fit (even got the crossover hose connected), kit is complete, and no more fuel smell when driving. What more could I ask for?

Fuel tank re-seal

works perfectly

Bit of a job

It was a bit of a job, but the replacement parts were as good as the originals.

Great Kit

Awesome complete kit and good quality.
I own a little shop in Hood River, OR and recently used this kit to seal customer van and it turned out great.

Amazing

Fit perfect and was easy highly recommend

No more fumes!

Great upgrade for your worn out tank!

Can finally smoke at the pump again.

Finally bit the bullet and had the tank resealed and vapor tanks replaced. No more gas spewing forth every time I fill up.

Own a shop used at least 20 . Work great

Came with everything needed

Everything fit well and i followed gowesty instructions.

Id recommend taking the rubber gaskets off the balancing tube and installing them on the gas tank THEN pressing in the balance tube.

No leaks hopefully it lasts for another 30 years

Good Kit

The rubber seems to be good quality. Hopefully my fuel tank stays sealed up for years!

Fuel tank re-seal

Had a small fuel leak, so I bought this part for mechanic to install. Leak is gone!

Fuel Tank Reseal Kit

Everything you need in one package. Be sure to lubricate seals with silicone paste. O ring for sender is thicker than standard that comes with sender so wasn't used.

Why Wait?

Do you stop filling the tank a few gallons short of full to prevent fuel from puking out? That's no way to live (or drive). This kit has all you usually need to put things right. I should be good for another 25 years (about how long since the last time I did this).

Challenging but worthwhile

Thorough and robust kit and materials made an awkward and cramped project the best it could be. I had much more difficulty getting the balance tube grommets in than the video showed, but eventually succeeded by reaching in through the wheel wells. (after twice retrieving the grommets from inside the tank). Definitely recommend doing the fuel sender at the same time...
