I get gas fume smell (which I assume is coming from the carb (weber dgv) after running getting the engine warmed up and stop the engine, since I park the car in the garage is there a way to capture or stop the fumes from being released? A little concerning since I have a gas furnace. After a while though with the garage door open the fumes dissapate though....
 
Are you certain is coming from the carb & not from the emissions system?
 
charcoal cannister & gas return lines under hood & around the tank in trunk
 
Where are the unburned gas fumes from the carb going if the charcoal cnnister isn't hooked up?
 
When you shut it off that heat soaks in and the fuel gets hot and evaporates from the bowl and escapes through the vent. The canister only works when there is vaccum from the intake even when all that is workings. Otherwise when you turn the ingintion on after it is cold you wouldn't hear that click click click as the fuel pump refills that empty float bowl.
 
with the canister connected, how does it "suck" in the fumes? Wouldn't the fumes still escape through the air fileter?
 
There is a metal "can" in the trunk on the passenger side.
Make sure the rubber hoses going to it are not cracked, broken or missing.
I had this when I first got mine, the hoses were badly deteriorated back there so I was getting a lot of gas smell.

Ditto. It's called the vapor separator, and it's in the right rear fender well inside the trunk. A hose broke off of mine, and it actually started siphoning gas into the trunk after a fill-up one day :shocked:. Check those hoses!

Otherwise, mine makes a distinct smell after I shut it off, mostly from the carburetor. If you still have your catalytic converter right under the carb, it can get a bit toasty and put off even more smell.
 
Oh yeah - and having that heater ducting in place may help keep engine bay smells out of the cockpit.
 
One off the wall thing to check - make sure your fuel pump isn't still running when the car is turned off. I had a BGT that had a strong gas smell and that was it.

Like I said, off the wall but still....
 
pump is not running when the engine is off...

so when the engine is turned off do the fumes from the carb go into the carbon canister? Wouldn't the fumes just go out of the air filter when the engine is turned off?
 
I have a dgv on a no emissions car BE I dont get gas fumes.. sure theres not something else going on? Cracked fuel line. leak at filter filler neck to tank.
