How do you start a diesel generator out of fuel?

Starting a diesel generator that is completely out of fuel can be a bit more involved than starting one with fuel already present. Here are the general steps you can follow:

Ensure safety: Make sure you are in a well-ventilated area and wear appropriate protective gear, such as gloves and goggles.

Refuel the generator: Use an approved diesel fuel container to refill the generator's fuel tank to the recommended level. Be careful not to spill any fuel during this process.

Prime the fuel system: Locate the manual priming pump on your generator, usually found near the fuel filter or on the fuel pump itself. Pump the priming pump several times until resistance is felt, which indicates that fuel is reaching the system.

Bleed the fuel system: Locate the fuel bleed valve, typically located on or near the fuel pump or fuel filter. Open the valve to allow any air trapped in the fuel system to escape. You may need to use a wrench or screwdriver to open the valve.

Crank the generator: Once the fuel system is primed and any air is bled out, turn the generator's key or push the start button to crank the engine. The generator should start up, albeit possibly with a few rough idles or sputtering due to the need to purge any remaining air from the system.

Monitor the generator: Keep an eye on the generator as it runs to ensure it is operating smoothly and that fuel is being properly delivered to the engine. If any issues arise, consult the generator's manual or seek assistance from a professional.

Remember to always follow the manufacturer's instructions specific to your generator model. Additionally, if you are unsure or uncomfortable performing any of these steps, it is recommended to seek the help of a qualified professional or generator technician.
