Fuel Filter Replacement (Diesel Engines)
If you want to change the fuel filter yourself, here’s how
to do it:
CAUTION:
Diesel fuel is flammable. It could start a fire if
something ignites it, and you could be burned.
Don’t let it get on hot engine parts, and keep
matches or other ignition sources away.
First, drain any water from the filter following the
procedure for draining water listed previously.
Your vehicle’s engine should be off until the end of
this procedure.
The fuel filter is located in the engine compartment on
the passenger’s side of the vehicle, or 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.
