Re: Fuel filter and PCV location?
The fuel filter is located on the bottom of the fuel pump module. The fuel
pump module is located on top of the fuel tank. The procedure for removing
the fuel filter is this: Remove fuel tank from vehicle, remove fuel pump
module from tank, remove fuel filter from fuel pump module. (On fuel
injected systems, the best place to put the filter is in the suction side.)
The filter in your tank is somewhat better than the "bug screens" you may be
used to. Anything that gets through it is assumed to be small enough not to
plug the injectors.
The 4.0 liter six cylinder engine is equipped with a closed crankcase
ventilation system (CCV) and a fixed orifice valve. The fixed orifice valve
is located in the smaller one of those elbow fittings you are talking about.
If you want to service it, it wouldn't hurt to take it out and blow some
carburetor cleaner through it.
An FSM would be a good investment, but unless you drive a lot or plan to
modify the vehicle, it will sit on the shelf for the first few years.

Re: Fuel filter and PCV location?
A-ha! Leave it to Jeep and DC to make things even simpler. No
replaceable filter cartridge and no PCV. I thought that no spark plug
wires was a great idea - this is even better.
Earle: Does your manual indicate the service interval on that in-tank
filter? Sounds like a PIA to replace to me. Hopefully, it never has
to be serviced.
No need to clean the CCV components since I'm using M1 lubricants.
Acids and carbon that normally build up in the top-end never cause a
problem.
My owner's manual never mentions replacement of either, so I'm guessing
the fuel filter is a lifetime sort of deal, which is fine with me.
This thing is a blast to drive. The other day while waiting in a
drive-through line for coffee, a car ahead of me stalled. No one
behind would back up fearing they would lose their place in line. (?)
No problem! I turned the wheel and eased it over the 8" berm, parked
and went inside. Everyone in their Honda's watched in amazement. No
one in their $60,000 luxury SUV wanted to risk scratching their baby,
so they just sat there. Bah! Git-R-Done!
I simply shake my head and wonder why I didn't buy one of these 20
years ago. Thanks for the help guys.

I had to replace my fuel pump and now can't get rid of the gas smell.
I dropped it again and found one vent hose had come off. Still smell gas...
We put the ring on nice and tight and snapped the fuel line on good.
Coming up on top down season and it's gonna' stink!
