What year? I have a 97' and think it is located in the gas tank as one unit(feul pump, fuel filter, fuel gauge). Is this true and how would you replace the fuel filter in the gas tank? After how many miles should you replace it?

I just changed mine this morning. I have a 5.2 so I don't know how different they are. My fuel filter was located just above the rear axle on the drivers side. On the 5.2's, the filters on the 97's and up are located in the tank. The Jeep manual says the internal filter does not need to be changed. I assume only in extreme cases (such as fuel contamination) would you ever need to change it. J

right under the passengers seat. obviously on the outside. crawl under the rearand take a look. it's bolted to the underside of the body.

1.) open your gas cap.
2.) open hood and go to the big fuse box on pass. side. take out the fuel pump fuse.
3.) crank over the engine. it may start and then crap out or not ever start. just keep cranking for 5 seconds or so.
that should bleed any pressure that your fuel lines may have. don't forget to put that fuse back in before you start it back up, when you're done.

another thing to do is to do it in the morning before driving. that lets out alot of the pressure.

when you buy the filter, either buy the tool to get the clips out or buy 2 more clips. and a lot of fuel comes out when you unhook the quick-disonnects. not like gallons but more than you want all over you. so stay to the side when you do it.

good luck!!!!
