Fuel filter.
Put a drain pan under the clear tube sticking down, just above the front
axle (assuming 4x4). Flip the yellow lever on the base of the fuel filter
canister (located low on the rear of the engine on the driver's side). Now,
take a 1-1/8" socket wrench, and remove the black plastic cap from the top
of the fuel filter canister. Remove the cap, with the filter attached. I
then like to spray the inside of the canister with some brake cleaner - this
will flush any gunk down the drain,and will also clean off the Water In Fuel
sensor prongs.
Remove the old filter from the cap, remove the old O-ring, and put a new
O-ring (included with the filter) back on the cap. Lube the o-ring with
some diesel fuel. Snap the new filter back onto the cap (with the hole in
the center of the filter facing away from the cap), and re-install the new
filter. Tughten the filter cap by hand, then tighten it with the socket
wrench, just until the black cap and gray body are touching. DO NOT
OVER-TIGHTEN... you'll crack it.
Flip the yellow drain lever back to the closed position. Put the key in the
ignition, turn to 'ON', then just bump it to 'START' and release
immediately. This will cause the fuel pump to run for 30 seconds or so.
Once the fuel pump stops running, do this once more, then, start the engine.
Let it idle for a minute or so, until you hear the engine stumble (it may
even stall - this is just the air being purged out- not to worry. If it
stalls, just re-start it). Make sure you've got no leaks, remove the drain
pan, and you're done.
