A diagram of the fuel lines to a fuel tank on a 1978 CJ5 Jeep can be found in an automobile repair manual. Both Hayes and Chilton make this type of manual.
The 1978 Jeep CJ5 takes a sealed beam lamp. See sources and related links below for more information.
There is a fuse box underneath the dash below the steering column. The fuses should be labled.
almost all of the cj5`s had no tailgates and had permanant spare tire mounts. if you do have one either it was special ordered or someone did it later. that`s the difference with the 5 &7.the 7 was a little longer and had the tailgate with the swingaway spare tire mount. Actually the "FIXED BACK PANEL/RR SP WHL MOUNT" was a $12 option in 1978. I have the factory window sticker for a 1978 CJ-5 listing it. The 1978 Jeep sales brochure lists it under "Options and Accessories" as "fixed back panel and spare mount (CJ-5)".
The bigger frame motor mount of the 1978 CJ5 V8 goes on the driver's side. This side typically accommodates the larger mount due to the engine's weight distribution and the layout of the engine components. It's important to ensure proper alignment during installation for optimal performance.
