How To Install Sniper EFI Onto The Willys "Go Devil" Four-Cylinder In A Flatfender Jeep

Does it get any more iconic than a flatfender Jeep? The original Willys Jeeps were as close as you got to the World War II battlefield hero without having the discharge paperwork in your hands. The vehicle that Allied commanders couldn't praise enough made a great transition to civilian life. Even today, the basic shape of the Willys MB/CJ3A flatfender is the quintessential Jeep shape. Why? Being fair, the early flatfender Jeeps were utilitarian in nature, little more than the Willys L-134 "Go Devil" engine powertrain and two axles bolted into a frame with a body tub attached. With all of sixty fire-breathing horsepower ready to work, the Go Devil could be walked by just about every UTV on the market...and most of them have more amenities. But that isn't the point...you have one of the most pure, proven, basic four-wheel-drive machines that has ever been built. They are perfectly capable of going wherever they damn well please with ease.


For many, adding EFI of any kind to a Willys Jeep is sacrilege of the highest order. But the YouTube channel Turn N Burn decided to adapt a Sniper EFI Autolite 1100 to their "Submarine" Jeep. There isn't a straight-on application that works with the Go Devil engine. The Sniper unit won't directly bolt onto the Go Devil's manifold. The throttle linkage needs to be modified. The wiring and the clutch linkage might meet. But it works, and you will be shown what all needs to be worked over on the Willys in order to adapt the Sniper. You will also be shown how the EFI operates, and you will see EFI vs. carburetor performance on the same engine in the same Jeep.
