I got the filler neck setup on my '51 panel finished today. Since the truck body is virtually pristine, I was adamant about not cutting any new holes in the body or fenders. Instead I grudgingly cut an access hole in the wooden floor. The filler door wouldn't sync with the wood slats so I added a transition piece below to span across the boards and runners. The tank inlet is offset an inch to the right, further complicating matters.
To prevent vapor intrusion into the cab the cap is sealed with an o-ring, the tank is vented out the right wheel well, and the plate and filler door are sealed with foam weatherstrip tape. Obviously care will be required to avoid spillage when fueling.
