Fuel Filter Replacement
If you want to change the diesel engine fuel filter
yourself, here is how to do it:
{CAUTION:
Diesel fuel is ammable. It could start a
re if something ignites it, and you could
be burned. Do not let it get on hot engine
parts, and keep matches or other ignition
sources away.
First, drain any water from the filter by following
the water draining procedure earlier in this section.
Your vehicle’s engine should be off until the end
of this procedure.
If your vehicle has the 6.6L engine, the fuel filter is
located in the engine compartment on the
driver’s side of the vehicle. If your vehicle has
either the 7.2L or 7.8L engine, the fuel filters are
located in the engine compartment on the
driver’s side of the vehicle, and on the driver’s
side frame rail in front of the fuel tank.
1. Apply the parking brake.2. Unplug the water
sensor wire
connected to the fuel
filter and unscrew
the filter element.
3. Remove the filter element. If there is any dirt
on the filter sealing surface, clean it off.
Remove and reuse the water sensor float
switch located on the bottom of the fuel filter.
4. Install the new filter element.
5. Reinstall and tighten the filter container and
reconnect the water sensor wire to the filter.
6. Use the fuel filter priming procedure earlier in
this section to prime the fuel filter.
7. Tighten the air bleed valve by turning it
clockwise until hand-tight.
8. Start your engine and let it idle for
five minutes. Check your fuel filter and air
bleed valve for leaks.
