Have a 91 Accord that has strong gasoline odor only when engine is running, it is coming in through the ac vents. Any help would be greatly appreciated
No odor present when car is just sitting.

 

Have you check your injectors to see if it's leaking? Check the fuel rail. Pull the vacuum tube on the fuel regulator and see if there's gas in there.
When you get the gas smell in cabin, is your vents on circulation or out side air in?
Try it with the vent on circulation and see if the smell still there. Make sure you windows are closed. I am trying to isolate the issue whether it's leaking in the engine bay.
