In the tank on the fuel pump...don't need to change it. Wait till the fuel pump dies and drop tank and replace all the goods. They are designed to not have to be a replace item.

I added an inline fuel filter in the engine bay on my 03 4.0l. not too keen on the idea of a filter in the gas tank, adds a little extra piece of mind

That was the information I got when I called my Jeep dealer asking where the filter was. When most all vehicles have a fuel filter that needs changing every few years, and some like my diesel motor home that requires the two fuel filters to be changed every year, how in the world could Chrysler have possibly designed a filter that may never need changing? I wish I had know all this within the first 2-3 years of ownership i would also have installed an underhood fuel filter but now after almost 10 years it probably is a little late for that addition.

It's not literally SITTING in the fuel inside the tank, it's merely the top portion of the whole pump assembly and can be taken apart without removing the entire pump assembly. It's just that the surface area is so large that it really shouldn't ever need to be changed. However, a failing pump is so common that it will probably get changed within ten years of ownership anyways.

It's not just Chrysler. My 89 Mustangg has the same kind of filter in the tank as do many other vehicles.

Gee thanks, my 2001 is coming up on 10 years of age and I don't think I'm looking forward to dropping that fuel tank.
Has anyone ever installed an under-hood electric fuel pump on their jeep to keep from pulling the gas tank, or especially as a precautionary measure to keep from getting stranded in a very inopertune place? Will an electric one work in conjunction with the one in the tank without causing any undue problems? I know back in the 50's & 60's many times an electric pump was installed to get better performance from the old mechanical pump or instead of replacing a bad mechanical pump.

The reason the TJ's main fuel filter is and truly deserves to be called a lifetime fuel filter is due to its positively huge surface area. There are actually two fuel filters inside the fuel tank. One at the bottom of the fuel pump for the bigger stuff, and the very fine large surface area inside the fuel pressure regulator on top of the fuel pump.

All it takes is one look at the main fuel filter which reminds me of a very dense white felt-like material, to believe they aren't kidding when they describe it as a lifetime fuel filter. It truly will outlast the TJ when fed a diet of non-third-world country gasoline.

no problem, I'm always just Mr. Optimistic

Course, the problem isn't the dropping the fuel tank. It's where the Wrangler is going to drop you off when it happens. Dropping the fuel tank is actually VERY simple and can be completed in ten minutes once you know what to look for. Just needs a floor jack, two jacktands, a decent socket set, and screwdrivers.
