Re: Question about fuel filter
 

I'm having some performance issues with my jeep (120k) and I'm just
wondering if a dirty fuel filter could be the culprit.

With that much milage it's far more likely to be the O2 sensor
or a plugged cat. Although reduced fuel flow could be the cause.

Check your plugs for excess carbon. If they all show lots of carbon
it's your O2 sensor sending a false reading. If just a few are
ugly it could be leaky injectors. For that you need to do a pressure
leak-down test on the rail.

Re: Question about fuel filter
 

Where is the fuel filter on a YJ? The TJ is on top of the tank:

little shield along the outside of the frame just before the engine
compartment, and of course are change every thirty thousand miles.

Inside the frame rail, on the drivers side above the front half of the
spring. There's a shield you have to remove to get to it.
