We have a 1962 Jaguar Low Drag Coupe in the shop that had a horrible gas smell that smelled up the entire shop. This is due to the fact that gas tanks on these particular Jaguars vent to automosphere, thus having a very small amount of gasoline evaporating and stinking up the surrounding area. We solved this issue by using the following aftermarket charcoal filter: https://www.classicperformancerestor...th-a-fuel-tank

We used the 8 inch variant from the link I provided above, and the results are incredible, absolutely zero smell of gas after installing this charcoal canister. Wanted to share our discovery as I find this to be invaluable for any classic vintage Jaguar. I'll attach a photo of our Jaguar with the charcoal canister installed. Happy tinkering my friends!

 

Why is everyone of your post is about this costly carbon canister? Why don't you talk about the low drag coupe. People would be interested in that.

 

Starting in 1968 or there abouts, E-Types came with a carbon canister in the engine bay just left and above the battery. Sourcing an original part would be another option.

Don't ignore that the later cars with carbon canisters used non-vented fuel caps. Yours is likely vented. The non-vented caps have "NV" on the back side.
