i have a 74 super beetle convertible. the gas smell inside is drivin me crazy. i think it's origin it that plastic part right behind the dash. there are many small gas lines and tubes.
my question is. can i remove that part and just plug the hole in the filler tube. what does this thing do anyway. if it is only for emission control, i don't care. as long as the gas mileage does not increase.
any help or suggestions...
