I've had 2 Wagoneers, 77 & 78. They had 2 serious deficiencies. One was vapor lock. The engine compartments were so tight that it got no air flow. The 77 had a 401 engine. It got so hot that the gas would boil in the float bowl. Switching to electric fuel pumps located back near the tank helped a bunch.
The other problem was the gas filler hole was barely higher than the gas tank and lots farther back. On a steep hill, gas would flow out the hole. Later models with a sealed system didn't have that problem.
Oh - I HATED that t-case locker in the glove box. What kind of an idiot would put it there where you had to crawl across the seat to lock it?
