1. Locate the fuel filler neck: This is usually on the driver's side of the vehicle, behind the rear wheel well or towards the back of the bed, depending on the configuration of your truck (regular cab, quad cab, etc.). It should be clearly marked with a fuel pump symbol.
2. Open the fuel filler door: This is typically a small door near the fuel filler neck. It might be spring-loaded or require unlocking manually, depending on your truck's model.
3. Insert the nozzle: Diesel fuel nozzles are typically larger than gasoline nozzles. Insert the nozzle firmly into the filler neck.
4. Select the appropriate fuel: Make sure you're using diesel fuel, not gasoline. Using gasoline in a diesel engine will cause severe damage.
5. Fill the tank: Slowly dispense the fuel until the automatic shutoff engages. Don't overfill the tank, as this can cause problems.
6. Remove the nozzle: Remove the nozzle from the filler neck once the pump shuts off.
7. Close the fuel filler door: Ensure the fuel filler door is securely closed.
Important Considerations:
* Fuel Type: Use only the type of diesel fuel recommended in your owner's manual. Ultra-low sulfur diesel (ULSD) is the standard for modern diesel engines.
* Overfilling: Avoid overfilling the tank. Overfilling can cause fuel to spill and create environmental hazards. The auto-shutoff should prevent this, but don't force more fuel in after it stops.
* Spills: If you spill any fuel, clean it up immediately to prevent fire hazards.
* Owner's Manual: Consult your vehicle's owner's manual for specific instructions and recommendations. This is the best source of information for your specific truck model.
If you have any trouble locating the fuel filler neck or are unsure about anything, consulting your owner's manual or contacting a local mechanic or dealership is recommended.
