fuel tank. Turn off your engine immediately.
Then, have the water drained at once.
To drain water, do the following:
1. Stop and park the vehicle in a safe place. Turn off
the engine and apply the parking brake.
2. Remove the fuel cap.
3. Place a fuel-resistant container under the fuel filter.
The filter drain valve is located on the bottom of the
fuel filter.

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
