Running out of fuel in a diesel truck can be a stressful and costly experience. It is important to be mindful of the fuel level in your truck's tank and to plan your trip, including fuel stops. If your diesel truck runs out of fuel, you should not attempt to start the engine as injectors and other parts could be damaged due to a lack of lubrication. Instead, you should add fuel and then prime the fuel system by turning the ignition on for 30 seconds without starting the engine. This allows the pump to prime the system. If your engine does not start after several attempts at priming, you may need to take it to a shop for a proper diagnosis and repair.

What You'll Learn
Using the correct fuel nozzle position
The fuel nozzle is a crucial component of any diesel engine, and its design and maintenance are vital to the engine's performance and longevity. Here are some detailed instructions on using the correct fuel nozzle position when fuelling a diesel truck:
Firstly, understand the basic components of a diesel fuel nozzle. The nozzle typically consists of two separate pumps: one for gasoline and one for diesel fuel. These pumps are positioned on either side of the nozzle, each connected to a tube – one metal and one plastic. The metal tube is inserted into the gas tank, while the plastic tube connects to the vehicle's fuel tank.
When fuelling your diesel truck, ensure the nozzle is in the correct position by following these steps:
- Position the nozzle carefully into the fuel inlet of your diesel truck.
- Firmly insert the nozzle into the inlet, ensuring a proper seal to prevent any fuel spillage or leakage.
- Activate the nozzle by pressing down on the nozzle handle. This action will engage a lever inside the nozzle, activating both pumps simultaneously.
- Maintain a steady grip on the nozzle handle during fuelling. The metal tube filters gasoline through its walls, while the plastic tube ensures only diesel fuel passes into your vehicle's engine, preventing contamination from other fuel types.
- Pay attention to the automatic shut-off feature on some nozzles. Automatic fuel nozzles will stop the flow of fuel when the tank is full, preventing overflow. With manual nozzles, you must monitor the fuel level and shut off the nozzle manually to avoid overfilling.
Remember to practice proper fuel nozzle maintenance to ensure efficient fuelling and prevent damage to your diesel truck's engine. Regular maintenance includes cleaning, inspecting, and replacing parts as per the manufacturer's instructions. Improper maintenance, such as leaving the nozzle in direct sunlight or using too much fuel at once, can lead to nozzle damage and increased fuel consumption.

Bleeding the fuel system
Step 1: Identify the Key Components
Familiarize yourself with the engine and its diesel fuel system. Identify the fuel tank, fuel lines, fuel filter, and fuel injectors. Review the engine's fuel system layout and connections.
Step 2: Work with the Fuel Filter
Turn off the engine and remove the ignition key from the cylinder. Locate the fuel filter and check if it has a built-in bleeder screw. Position a clean rag or towel beneath the bleeder screw to catch any fuel spills.
Step 3: Loosen the Bleeder Screw
If the fuel filter has a bleeder screw, use a wrench or bleeder screw key to slowly loosen it in a counterclockwise direction. You don't need to remove the screw completely; just loosen it halfway or until you see fuel flowing out.
Step 4: Open the Bleed Valve
If your fuel filter lacks a bleeder screw, you may need to open the bleed valve. Turn the key to auxiliary mode to start the fuel pump. Open the bleed valve on the primary fuel filter. If fuel does not flow out immediately, run the pump for a few minutes before trying again.
Step 5: Close and Open Valves
Close the valve on the primary fuel filter and open the valve near the secondary fuel filter, if applicable. This will allow fuel to flow out of the secondary filter.
Step 6: Prime the Fuel System
After adding fresh diesel, turn the ignition to the "Run" position for 30 seconds without starting the engine. This allows the pump to prime the system. Then, turn the ignition off and crank it for 15 seconds. Repeat these steps until the engine starts.
Step 7: Final Checks
Once the engine starts, allow it to idle for several minutes and check for any leaks. If the engine stalls, wait for one minute before attempting to start it again. If the engine does not start after several attempts, have the truck towed for proper diagnosis and repair.
Step 8: Clean-up and Maintenance
Properly dispose of any spilled fuel and clean up the work area. Return your tools to their proper locations. Consider replacing your fuel filter or upgrading to an AirDog® fuel system to reduce the likelihood of future bleeding and improve fuel economy and engine performance.

Priming the fuel system
Priming a diesel engine is the process of filling the engine with working fluid (diesel) and removing contaminants from the diesel. This process is essential to ensure the engine runs efficiently. It also involves delivering high-pressure fuel directly into the fuel system, ensuring the entire system is pressurised and lubricated.
Before attempting to prime the fuel system, it is important to familiarise yourself with the engine and its key components, including the fuel tank, fuel lines, fuel filter, and fuel injectors. Review the engine's fuel system layout and connections, and determine whether the fuel filter has a built-in bleeder screw. If it does, position a clean rag or towel beneath the bleeder screw to catch any fuel spills, then use a wrench or bleeder screw key to slowly loosen the screw in a counter-clockwise direction.
If the fuel filter does not have a bleeder screw, you may need to loosen the filter slightly to allow air to escape. If you suspect air remains in the system, you may need to bleed the fuel system at the fuel injectors. Locate the engine's fuel injectors, typically connected to the fuel lines, and use a wrench or socket set to loosen the fuel line connection. Crank the engine for a few seconds to allow air to escape, being cautious of fuel spills, then tighten the connection when you observe a steady fuel flow without air bubbles.
To prime the fuel system, turn the ignition to the "Run" position for 30 seconds, but do not start the engine. This allows the pump to prime the system. Then, turn the ignition off and crank it for 15 seconds. If the engine does not start, repeat the process until it does. If it still doesn't start, take a break and then try again. If the engine starts but immediately stalls, wait for one minute before attempting another start. Once the engine starts, let it idle for several minutes and check for leaks before driving.
If the engine still won't start, it may be necessary to tow the truck to a shop or dealership for further diagnosis and repair.
