Contrary to claims by Toyota, fuel filters are NOT liftetime parts. Ok,
this is anecdotal information based on members from Yotatech and other
forums who have experienced dramatic changes in their vehicle's acceleration
and throttle response. Not to mention, cleaner fuel running through your
fuel delivery system.
It's a relatively simple, inexpensive change and can be done in less than
one hour. The only difficult part seemed to be getting off the compression
fittings within the tight confines under your 4runner.
SPECIAL WARNING (Because America is a litigious
society full of dolts and trial lawyers who love them)
Hey Cletus, if you are stupid enough to be smoking while doing this mod,
you've earned your right to be in the idiots hall of fame. If you are
dumb enough to be lighting matches to see where the fuel is leaking from,
you'll probably become your neighborhood's first car bomb casualty. If
your idiot chain smoking friend comes by for a visit, encourage him to
raid your fridge and watch Sports Center while you finish this. Do anything
to keep him from visiting you underneath your car. Nancy Kerrigan him
or something. Do anything, just keep those flames away!!!
Step 1: Locating the Fuel Filter
For whatever reason, people seem to have a hard time finding this little
bugger. Look at the pictures below. The fuel filter is located on the
driver's side of the vehicle. In fact, the area under the steering wheel
is almost directly above the fuel filter. Imagination aside, the fuel
filter sits just inside the driver's side frame rail, slightly behind
the front crossmember and slightly to the left of the driveshaft and the
front transfer case (if you have 4WD).

Step 1: Depressurizing and Removing the Fuel Line Compression
First, put on your goggles or any other kind of eye protection. You'll
thank me for it later. :) Begin by opening your gas cap to partially depressurize
your fuel line. Of note, if you want to fully depressurize the fuel lines,
take out the pump fuse and start the engine. This is optional and does
not need to be done, but just for your reference.
Next, spray a good amount of penetrant on the compression fitting threads
to start the loosening process. I found on my 4runner that the front one
was the most difficult of the two because of the tight space not allowing
for good leverage. I positioned myself to work on the front compression
fitting by working from the front of the cross member. Much easier.
to the rescue
front fuel line for stability and loosen the front compression fitting.
Using a 14mm crow's foot wrench w/ a rachet is the best tool for the job,
but I got by with a regular 14mm combo wrench. Next, remove the rear compression
fitting and then pull both fittings back *away* from the fuel filter.
remove either of the fittings, you will see that the fuel will start to
drip and/or spill out. Place your bucket underneath the fuel filter and
let it drain until there's a slow drip. If you give it a few good shakes,
more should come out.
Step 2: Removing the Fuel Filter Mounting Screws and Fuel Filter
Save yourself some headache and go find your 6" ratchet extension.
Put a deep 10mm socket on the end of the extension and rachet and remove
the two mounting screws. The 6" extension will allow you to rotate
the rachet at full circles vs tiny little ones.

fuel filter loose. At this point, alot of fuel will drip out. More than
you probably expect. It's completely normal so just shake it loose and
then put in a safe place away from flames to drain.
Step 3: Mounting the Fuel Filter
One common question is "proper orientation of the fuel filter."
Looking at the top and bottom of the filter, it is stamped either "In"
or "Out". The "In" side faces the rear part of your
4runner while the
"Out" side faces your engine.

ends of the fuel lines into the fuel filter. Move and mount the fuel filter
upwards and then screw in the mounting threads loosely until it can hold
the weight of the fuel filter. Now adjust the fuel lines until they are
perfectly seated in the fuel filter and then slightly tighten down the
compression fittings. Alternate tightening all the screws by hand until
the fuel filter is seated correctly. Only then should you fasten down
the pair of compression fittings and mounting screws with your 14mm wrench
and 10mm deep socket, respectively.
Note: while this may seem cumbersome, I've read one or two threads where
people said that their fuel filters sprayed fuel once they turned on their
vehicle. This is from the fuel line not being properly seated because
the compression fitting threads are not properly aligned (gaps) and cannot
be tightened down.
