What You'll Learn
Locating the fuel gauge
The fuel gauge will be located somewhere on the generator's fuel tank. It is usually a small, discrete component that may be difficult to spot. The fuel gauge may be on the exterior of the generator, or it may be located inside, requiring you to open up the generator to access it.
If you are having trouble locating the fuel gauge, refer to the generator's manual. The manual should provide a clear diagram and instructions on how to access the fuel gauge. This will ensure you are checking the correct component and avoid any confusion with other similar-looking parts.
Once you have located the fuel gauge, you can proceed to check the sensor. This may involve inspecting the gauge for any signs of damage or discolouration, which could impact its accuracy. Additionally, you may need to clean the gauge and its surrounding area to ensure that contamination does not affect the readings.
For Generac generators, the fuel gauge is often praised for its ease of installation and user-friendly design. The Generac 0H9005 Fuel Gauge 130LG, in particular, is known for its accuracy, durability, and compatibility with various generator brands.

Reading the gauge
Locating the Fuel Gauge:
The fuel gauge is typically found on the generator's control panel. It displays the current fuel level, usually in percentage or fractional readings. If the reading is in feet or inches, you may need a supplementary Tank Chart to calculate the exact fuel volume.
Cross-Checking the Gauge:
To ensure the gauge is functioning correctly, it's essential to cross-check the reading with manual methods periodically. This can be done by accessing the fuel tank and using a dipstick or a wooden gauge stick to measure the fuel level. Insert the dipstick slowly into the tank until it touches the bottom, then remove it and check the marked fuel level. Compare this reading with the tank's capacity chart to determine the precise fuel volume.
Monitoring Fuel Sensors:
Modern generators often have fuel sensors that provide real-time data on fuel levels. These sensors can be linked to a monitoring system, which allows for centralized monitoring of fuel levels alongside other vital alarms. Additionally, you can receive proactive alerts when fuel levels drop, helping you dispatch refueling before an emergency.
Understanding Fuel Sending Units:
The fuel sending unit is a critical component that measures the fuel level in the tank and communicates it to the fuel gauge. It consists of a float, a metal rod or arm, and a variable resistor. The float moves up or down according to the fuel level, causing the metal rod to pivot and the wiper inside the resistor to move. The wiper's position on the resistive material strip determines the strength of the electric current, which corresponds to the fuel level displayed on the gauge.
Testing the Fuel Gauge:
To ensure the fuel gauge is functioning correctly, you can perform simple tests. Check that all wiring connections are clean, tight, and free from dirt and corrosion. Turn the ignition on and off several times and observe if the needle moves; if not, check the fuse and replace it if necessary. You can also connect a jumper wire to the ignition switch and the terminal on the back of the fuel gauge to test its functionality.

Cross-checking the gauge
Cross-checking the fuel gauge on a generator is a crucial step in ensuring accurate fuel level readings. Here are the steps you can take to cross-check the gauge:
Locate the Fuel Gauge
The fuel gauge is typically found on the generator's control panel. It displays the current fuel level, usually in percentages or fractional readings. If the reading is given in feet or inches, you may need to refer to a supplementary Tank Chart to calculate the exact fuel volume.
Manual Cross-Checking Methods
One way to cross-check the fuel level is by using a dipstick. First, ensure the generator is turned off and cooled down for safety. Open the fuel tank cap and slowly insert the calibrated dipstick into the tank until it touches the bottom. Then, remove the dipstick and check the fuel level marked on it. Compare this reading with the tank's capacity chart to determine the precise fuel volume.
Check the Fuel Sending Unit
The fuel sending unit is responsible for measuring the fuel level in the tank and communicating this information to the fuel gauge. If the gauge is malfunctioning, the issue could be with the sending unit. Check the wiring connections on both the gauge and the sending unit to ensure they are clean, tight, and free from dirt and corrosion. If the problem persists, consult a mechanic or consider replacing the sending unit.
Turn the Ignition On and Off
Another way to cross-check the gauge is to turn the ignition on and off several times and observe the needle movement. If there is no movement, check the fuse and replace it if necessary. Consult your service manual to locate the fuse panel and identify the correct amperage rating for the replacement fuse.
Compare with Other Methods
You can also cross-check the fuel gauge by comparing it with other methods of measuring fuel levels, such as using a small dial gauge or a wooden gauge stick, along with a tank chart to calculate the fuel volume. Additionally, maintaining a log of fuel levels and consumption rates will help you identify any discrepancies in the gauge readings over time.
By regularly cross-checking the fuel gauge, you can ensure accurate fuel level measurements and prevent unexpected power outages due to insufficient fuel levels.

Using a dipstick
To use a calibrated dipstick, simply insert the stick into the tank and note the fuel level marked on it. Then, compare this reading with the tank's capacity chart to determine the exact fuel volume. Calibrating a dipstick is simple and only requires a few steps. Start with an empty tank and add a known quantity of fuel (for example, one gallon). Insert the dipstick and mark the wet line. Repeat this process, adding known quantities of fuel and marking the corresponding levels on the dipstick, until the tank is full.
Uncalibrated dipsticks can also be used to measure fuel levels in inches. Similar to calibrated dipsticks, you insert the uncalibrated dipstick into the tank, note the fuel level, and then compare this reading to the tank's capacity chart.
While dipsticks provide highly accurate fuel level measurements, they can be time-consuming to use. The process involves removing the dipstick, opening the top of the tank, inserting the dipstick, pulling it out, reading the measurement, cleaning the dipstick, closing the tank, and then storing the dipstick. Nevertheless, the accuracy of a dipstick is difficult to match, and it is recommended to use a combination of dipsticks and fuel gauges for evaluating fuel levels.

Monitoring fuel levels
Manual Methods
The most common way of monitoring fuel levels in diesel generators is through manual paper logging. This involves inserting a wooden gauge stick or a calibrated dipstick into the tank to measure the fuel level in inches or feet. This reading is then converted into gallons using a supplementary Tank Chart. Another manual method is to read a small dial gauge, which provides a fractional reading (e.g., ¼, ½, ¾). However, manual methods can be inaccurate and time-consuming, especially during emergencies.
Fuel Level Sensors
Fuel level sensors provide real-time data on fuel levels. Ultrasonic or float-type sensors can be installed in the generator's sub-base or day tank. These sensors are connected to a monitoring system, which allows for centralized monitoring of fuel levels. Sensors can also trigger alerts when fuel levels drop, facilitating proactive refueling and reducing the risk of unexpected outages.
RTUs (Remote Terminal Units)
An RTU, such as a NetGuardian, acts as a central hub for fuel level data. It collects information from fuel sensors and transmits it to a central location, allowing you to view fuel levels alongside other vital alarms. This simplifies monitoring and helps prevent unexpected outages.
IoT Cloud Remote Monitoring
IoT Cloud Remote Monitoring solutions, such as GenApp, offer a secure way to monitor fuel levels without the need for a building data connection. This external system can be shared with vendors to ensure reliable fuel delivery and generator operation. The system provides daily updates on fuel levels and performs verification checks every 10 minutes, ensuring accurate record-keeping for fuel consumption.
Fuel Gauge and Sending Unit
The fuel gauge and sending unit work together to measure and display the fuel level. The sending unit is located in the fuel tank and consists of a float, a metal rod, and a variable resistor. The float moves up or down according to the fuel level, causing the metal rod and wiper to pivot, which then sends an electric current to the fuel gauge for display.
By employing a combination of these methods and maintaining clean equipment and accurate records, building engineers can ensure their generators are properly fueled and ready to provide backup power when needed.
