Mine which was added soon after purchase for the Mexican rally went down directly behind the bucket at about 4 o'clock looking down on it from the rear. Photo attached. The hose exited straight down from there in a crudely made hole. If you look closely at the photo of the tank installed, you can see the hose. My hose was just visible from the back of the car. It hung down about 1/4" but still stained the paint from the drip and fumes. The seals around the tank were very bad. I resealed it a couple of times and still could not get it. A previous owner opened up the skirts below the battery and on the left side to create better ventilation. For me, the secret was not to fill it more than about 1/2 way.
