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!

 

So, are you still venting to the atmosphere but first passing through the charcoal canister?

 

Yes, that is correct. Activated charcoal is incredibly effective against gasoline vapor, and is very good at holding it. The charcoal lasts many years, and if for any reason, you can easily replace the charcoal with new charcoal.

 

Clever idea, well done. Readers unfamiliar with their cars should remember however that the banjos on SU carbs (for those with SUs!) are notorious for leaking - lots of people I know keep the correct size spanner to hand at all times! So don't assume your smell will be fixed by the above clever upgrade unless you check this first.

 

@JagVintage4367, The reason I asked if you were still venting to the atmosphere, is because on my 914 the return vapor line from the charcoal canister (factory installed) goes all the way to the back and connects to the engine intake. I was wondering where you connected the other hose to. I imagine that on a street e-Type it could connect to the stock location at the gas filler neck. Or is that a bad idea?
