Jeep fuel systems have many parts to them. People are often surprised when they find out just how many parts make up a fuel system. Most of these parts are quite common and you’ll find them in most vehicles, not just Jeeps. However, when something goes wrong with your Jeep or if you are restoring one, you will want to know what some of the common Jeep fuel system parts are.

There are twelve common parts of the Jeep fuel system. The throttle and accelerator parts control the accelerator and the throttle. It is vital that these parts be kept in good condition because if either goes out it can mean that you could have a serious car accident or simply be unable to drive. The carburetor is another essential part and if not kept in good condition, could cost you a small fortune to repair. It’s easy to buy the parts and keep it in good condition. Filter necks and hoses help direct where the gas is going. The filter neck makes sure it ends up in the tank, and the hoses make sure it gets to the engine. Leaks are serious problems.

Other parts of the Jeep fuel system are the fuel injection units, fuel pumps, fuel lines, and fuel sending units. All these parts have to be in working order if you want to have an engine that purrs like a kitten. You have to make sure that there are no leaks in the system, or you can have gas coating the engine which is a serious hazard. It’s simple to replace the parts yourself, and much cheaper than if you were to take your Jeep to a mechanic.

Some other common Jeep fuel system parts are the gas tanks and gas caps. It is very important that you only install the same size gas tank that your Jeep was made for. Adding larger or smaller tanks can leave gaps that could prove dangerous or you will have to squeeze the tank in, something else that could be dangerous. Plastic gas tanks are fine, and are often cheaper, than steel ones. The problem is that they crack much more easily and are not going to last as long. Gas caps that lock are very popular because people are not able to siphon gas out of your tank although you don’t need them if your vehicle has an automatic lock.

  1. Thanks for the lesson. I had no idea it was that complicated. I do know that it’s just one more reason why I take my Jeep to a reputable mechanic. If I tried to touch anything like that I’d be one of those who would have left over parts when the job is done! Not a good idea and I will be the first to admit my deficiencies.


  2. That does not look like a walk in the park to me. I guess I’m mechanically challenged. Heck, I can’t even work the electric can opener consistently. I think all of the mechanical genes went to my younger brother. I guess I should be glad that I have him to do my ‘dirty’ work. He has tried to teach me the way around a vehicle but he finally gave up and made me leave the garage for good. I’ve been banned from my own garage and by my baby brother no less!


  3. I ruptured the fuel line at the end of November and with the help of a friend of mine we put in a new one. You’re right about it being cheaper. I saved a couple of hundred dollars by doing the work myself. I actually felt pretty proud of myself for getting the job done too.


  4. It’s not as complicated as it looks. The instructions were clear and working on the fuel system was not the nightmare I envisioned it would be. My oldest brother is a mechanic and he was watching my progress but I actually got the job done without his help. Never hurts to have a second pair of eyes watching to make sure it’s done right.
