have any of you sealed the two floor board holes under the gas tank... I was thinking of placing a 1/2 thick foam circle that would seal the floor / gas tank...which would stop the air from flowing from under the truck to the under seat area... was this left this way to vent out gas fumes.. but there are dangers from engine fumes coming up.. and a well sealed tank won't off gas. but from the cap.. pro's or con's please help
