Fuel filter and PCV location?
I'm looking to change the fuel filter on my '05 TJL, but I haven't
found the darned thing. I don't see a PCV either - both on top of the
valve cover look like elbows, not valves.
Someone mentioned that recent TJ's don't use replaceable fuel filters,
and I don't consider the bug screen in the tank to be a suitable
substitute. This doesn't make much sense to me. Even using clean
fuel, I've had to replace filters yearly in the past because they get
so choked up that you can't even blow air through them. What's the
deal on this? Are the injectors so large that they just don't care
about the really tiny stuff in the fuel anymore?
I guess the obvious thing to do next would be to find a factory service
manual.

No worries, you don't have either of them as far as I know....

Re: Fuel filter and PCV location?
Wouldn't he have the combination fuel filter-regulator?
On my ''02 WJ it is attached to the floor panel in front and above the fuel
tank. They are designed for long service life and must be replaced when
that time comes...

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.
