Tip for a smelly garage!



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!

Expandtion could flood carb I suppose, contraction just sucks air thru check valve. I need suggestions on a small charcoal canister, maybe for a motorcycle.
Thanks!

I was concerned about this too, and, since I don't have enough Vacuum for the Cannister that was out. I took a tip from Ireland's Child and put two loops of Hose after the Tank (above the Tank), and, I put a small Ball Valve at the end of my Vent Line so that when I put it away I will shut it off-not the sexiest of solutions, but I think it works-

I use a standard gas line filter on my vent line. No problems at all.

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.

Glad you got smell fixed. If it had been me, I would have gotten a new wife. LOL

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

I tried that. I took a small radiator overflow tank and filled it with activated charcoal, starting smelling gas after a short while again. Besides, if you don't have a way to purge the fumes from the tank, seems like you've just built a bomb!

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.

OK! Here is what I have and have done today! Hope the hell it works! I used a puke tank and screened the lines inside and filled it with activated charcoal and attached it to a fuel filter and then on to the curley-q on top of the tank!

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

Your a better man than I, I would have told her to go in the house. Nice work anyhow

[Curmudgeon29]

OK! This was this mornings project. Still smelled gas, off came the canister.
I came off the curley-q with 3 loops as high as and behind the tank.
Then I dropped through the floor and attached a fuel filter with 1/4"
fittings then from the filter a 3' line terminating in the frame rail.
This afternoon it was 84 degrees---No smell!

looks like a pretty neat hot rod.
