Fuel stench in garage?

[493 Mike]

I am looking for a pair of shut off valves for my fuel cell vent lines. I'm using 1/2" aluminum tubing for the vent lines. If I could shut down the vents while in the shop it would sure smell better! No luck with my search so far. Any ideas fellas?

I don’t think you’d want to do that. You risk pressurizing (or the reverse) the system and potential catastrophic problems or dangerous situations

Maybe add a charcoal canister or equivalent

Are you super sure that the fuel vapor is emitting from the vents? The photo looks like the tank is missing a fuel pump. Check for all paths to atmosphere before thinking about blocking vents.

Here's what I did...I installed an inline check valve off of the vent tube. That way, as pressure builds inside of the tank, the valve will open and release the pressure/fumes into the atmosphere. That helped a ton with the raw fuel smell.

Old photo, before any fuel was added.

It would only be for garage storage. I would open and close them during operation. I think I have a solution, after a trip to the hardware store. They sell 1/4" brass ball valves and with flare adapters it would be easy to accomplish. I was thinking I could find something in the AN series. I did just order a billet aluminum filler with a screw-on cap for $30.00 (Chinese). I could not rationalize a Aeromotive set up for $300.00!

It needs to vent to avoid excessive pressure build up or implosion from negative pressure situation. You CAN do whatever you want but I sure wouldn’t do that. If you’re worried about smell park the car outside for an hour or two after use, them pull in your shop after it’s cooled down and things have settled.

Find some fuel tank vapor solenoids that are normally closed and actuate them when its running. About 12 to 14 bucks on e-bay.

Maybe this Mike. I'm probably going to get one of these too when its time.

Personally, I like the smell. Also diesel! Old age probably!!

I started with a check valve from Pegasus Auto Racing. That helped some for the regular fuel evaporation. But, when the fuel in the tank expands, the check valve "burps" and the vapor smell was back. I installed a "Vapor Trapper" from Shop 48 and it virtually eliminated all gasoline smell. Well worth the investment, particularly with my garage attached to my house. The Vapor Trapper must be installed above the fuel tank so no liquid gets into it. The Check Valve helps with that during "Unplanned Sudden Acceleration"! I mounted mine above the tank and routed the vent line back thru the trunk floor to the atmosphere. Highly recommend this product.

I did not realize this product existed. Thanks for the link!

A very nice and clean install. However, all those direct hard-line connections without ANY flex tube connections concerns me in a hard crash with a filled fuel cell.

I always just shut my fuel pump off as I enter my street. By the time I pull in and up in the driveway and into the garage I let run for a few more minutes until the car sucks the carbs dry and it dies. I never have a bad fuel smell in the garage and my garage is attached and I never smell anything in the house either.

For some reason I suspected OP 's set-up was EFI, and not having that luxury.

Can you explain to me how the vapors are removed from the charcoal. Once they are saturated and can hold no more, what happens? OEM canisters have a purge function to desaturate the charcoal. I have e-mailed Aeromotive asking for their recommendation. I have another problem in that mounting the canister 8" above the cell means it would be on top of the deck lid!

I am considering the ball valves I mentioned earlier and think a tiny hole drilled through one of the balls in closed position would limit vapor expulsion and not cause any pressure changes. What say ye?
I believe the returning of gas to the cell heats the fuel, making it more volatile, exasperating the issue. My fuel lines do pass the right rear header tube where they may pick up heat. Even though they are insulated.

I believe the "tiny hole" solution will only change the speed of which the vapors are released, not the amount, unless temp drops significantly during the time period.
But we must accept above freezing? there will always be evaporation from the liquid fuel.

At the risk of getting a virtual ear-bashing...... I have not noticed any fuel smell in my garage since I have been running a Sniper EFI unit.

Carbs just blurted out the stench of fuel all the time. I put that down to fuel boiling in the bowls after parking up......and that continues until it is pretty much all vaporised.

Go EFI if you haven't already done so.

FAST 2.0. The problem is solely due to the fuel cell vents.
My 65 Coronet with 318 poly does boil the fuel out of the float bowl (which does stink up the parking garage). That is the fault of today's gasoline.
