You will get a bit when you first park the car from both the carb and exhaust - a non EFI car, unfortunately has these 'gas leaks'. This is especially true with an aluminum Edelbrock Performer carb, and somewhat worse without a phenolic spacer to shield it from the engine heat. But this system works

Please keep us updated!

I need to do something on my '63 T'Bird and this looks like it could be a winner!

Thanx,

I don't know if it'll work (I do think it will), but that's a hell of a clean installation! Nice job!

If you're still smelling fumes after passing these fumes through an activated charcoal canister, a few thoughts come to mind- since a correctly sized fresh activated charcoal filter will remove gas smells:

the canister isn't big enough, or has old, gassy charcoal in it

the fumes are coming from the cap or some other place than the vent line- like a cracked rubber connection between any of the gas or vent lines to the tank

As far as a bomb goes, most any gas tank has an explosive atmosphere inside it. Using a charcoal filter is less of a hazard than venting the fumes into the air I would think.

Curmudgeon29 I have a coil of tubing in my vent line just above my tank, that doesn't seem to help. Someone on the H.A.M.B. suggested attaching a fuel filter w/1/4" fittings to the vent line so the tank could breath. That seems to help, but it's not the cure all.
It was also suggested to run a vent line as high above the tank as I could and create a 180 then back down, kind of like a upside down J trap. I don't see how that would make any difference.
Again, the fuel filter on the end of the vent line does seem to help!
ANY OTHER IDEAS?????

Thanks! Joe

My wife has complained for sometime now about the gasoline smell in the garage, so I have been trying to find a cure and I think I have!
Both of my cars have a 1/4" ID vent hose from the tank top exiting under the car.
I found a Dorman #47149 vacuum check valve in the Help Section at my parts store. It's very small and fits the 1/4" line.
It draws enough air while driving and doesn't restrict fuel flow.
The Smell is Gone!
Glad you got smell fixed. If it had been me, I would have gotten a new wife. LOL

Originally I had intended to use a charcoal system out of an early 80's GM but this worked very well instead.
I have used this same thing, have one on my DD Malibu wagon as we speak. Just tuck it out of the way, pointing down so no water, etc. can get into it. But my car is outside so I don't know how well this would stop the smell of gas inside a garage.

As for a charcoal canister, I'd imagine an OE vapor canister would work just fine. It wouldn't be plumbed for vacuum to pull vapors into it, but as l9ng as the vent line that is causing the fumes in the garage is connected to the canister, the fumes will have to pass through the activated charcoal.

I'd source one from a 'yard, from a small car/engine so it would be compact. Refresh the charcoal if needed, run the vent line into it and you're done.
