I have written about this before . . . . .
I am curious and maybe somebody can point me to where I can get more information.
I HAD the heavy gas smell / vapor problem. Not just the odor of gasoline, but vapor strong enough to start a gag reflex. Also, when I would fill up the Spyder ( a new 2008 SE5 ) when the light came on, it would only take about 3.5 gallons, but the top bar and triangle never darkened. There would be at least one episode of gasoline vapors in every ride.
All that stopped around 2,650 miles a couple of months ago. No gas vapors. It now takes 4.5 to 5+ gallons at fill-up when the light comes on. All the bars are dark on the indicator.
In another posting, Scotty mentioned that it sounded like the Purge Valve could have been stuck and was now unstuck. I should have asked at the time, but since everything was fine, I didn't - but, where can I find out more on how the purge valve and evaporation canister work? I get the premise, but not the mechanics.
This mod sounds like a solution that works and you cannot argue with success, but I would like to know more - just in case the problem comes back.
Thanks
Tom
You may be able to purge a...
evap canister that has been flooded by and over filled tank. Put it under your outside shed and focus a shop spot light on it at a close range. This will keep it nice and warm for a few hours and all the gas will evaporate.
