T7 Gas Tank Cap Seal - Yamaha 700 Tenere

$12.00 USD

An annoying issue with the T7 is its leaking fuel tank cap seal. The cap has a spring-loaded seat under it, and if there is any downward pressure on the cap other than straight down, the cap rocks slightly, and the seal starts to leak.

I know you're thinking, "Why would there be pressure on my fuel cap?!". If you use a tank bag, it will sit on top of the gas cap, and it can apply pressure. If you drop your bike and the tank bag is pushing on the cap, there's a good chance it (and its contents) will be soaked with gasoline... way less than ideal.

This leaky cap problem also creates issues for our Camel Tank customers. Fuel is transferred from the Camel Tank to the main tank using vacuum. If the main tank cap doesn't seal properly, no vacuum is created, and the fuel won't transfer properly.

Our 1.5mm thick Viton sealing ring is a quick, cheap, and effective way to keep the gas and fumes in your fuel tank.

We are now including TWO 1.5mm Viton seals in each kit. Some bikes don't have room for a 3mm seal, and others won't seal with a 1.5mm seal. Start with one seal and add the second if needed!

Simple fix

My '21 needed 3mm (2 viton seals included in purchase) and now it doesn't leak fuel on tip overs. works as advertised!

No more leaks!

Having tipped over a few times without the seal, I quickly realized that fuel would occasionally leak down the side of the tank. Given that I was also planning to mount a tank bag for touring, I decided to buy this seal, and since then, I haven’t had a leak.

Fuel cap seal

I run the camel rear mount 5lit tank, it’s a simple fix for fuel range and well weighted (not noticeable)

I also use a tank bag and found on occasion had a vacuum leak, I recently installed added seal its tightened the cap up

Should be Problem solved

Works as described

I had not laid my bike over or experienced leakage/odor prior to installing this. I did notice the cap did have some "play" and was not as tight as it could have been. This is a simple, cheap add on that I see as pre-emptive and a no brainer.
