Where is the fuel filter on a 2004 TJ with the 4.0 motor? Is there one? :surrender:

Yep the fuel filter was purposely designed with a positively huge surface area so it doesn't have to be changed as part of routine maintenance. It is considered a lifetime part, so much so you have to drop the gas tank to even get to it.

Again never, unless you live in a 3rd world country whose gas pumps don't filter the fuel. Once again, the factory designed it to be a lifetime filter. If it needed regular changing, the factory would not have mounted it inside the gas tank.

I have definitely heard of people changing them though. But don't worry about it unless you have problems that you know that's the source of.:thumb:

Yes but usually only in a misguided attempt to fix a problem not caused by the fuel filter. Many of us grew up in times when the old inline glass fuel filters did need regular cleaning/changing so with some, old habits die hard. Many hang onto those old habits so "change the fuel filter" is the advice given by many who don't realize today's filters are usually lifetime and don't need routine changing.

Thanks. I didn't know there wasn't one you could change. This is the only vehicle I've ever owned that has it in the tank. My GMC Z71, my S10, my Cobalt and the wifes Alero all have one that you can swap out.

Just a little more info, the fuel filter is not replaceable by itself, it is contained inside the fuel pressure regulator. If you want to replace the fuel pressure regulator, you have to do so by replacing the fuel pressure regulator which I am holding in my hand in the below photo. The old FPR I am replacing can be seen on top of the gas tank.
