no return line used. no line into cell from valve. there was no sloshing of fuel. its just been sitting, had it running a few times but didnt move the car. theres foam in the cell. i thought that might block any sloshing if /when driving.
could it be just from vapors from temp swings in the garage?
i should mention that its not alot of fuel on the floor. since yesterday theres about a 5" wet spot on the floor, but its enough to fill garage with alot of fumes.
i dont have a loop in the vent line though. how does it vent if theres fuel in the loop?
thanks.
