What You'll Learn
Check for a crossover line
To equalize fuel tanks, it is important to check for a crossover line. A crossover line is a connection between two fuel tanks that allows fuel to flow between them, keeping the fuel levels equalized. This is especially important in systems with a single return line, as it helps to balance the fuel levels and prevent one tank from being overfilled while the other is emptied.
In some cases, newer vehicles may have two separate fuel tanks that do not require a crossover line. These systems, known as ""top draw" systems, draw fuel from both tanks simultaneously, eliminating the need for a crossover line. However, in older systems or those with a single engine, a crossover line is crucial for equalizing fuel levels.
To check for a crossover line, inspect the fuel system for any lines or hoses connecting the two tanks. Typically, the crossover line will be located towards the bottom of the tanks, providing a path for fuel to flow between them. In some cases, there may be shut-off valves or check valves inline with the crossover line, allowing you to control the flow of fuel and balance the levels manually.
It is important to note that a crossover line may not always be visible or easily accessible. In some cases, it may be hidden behind other components or located in a hard-to-reach area. If you are unsure about the presence or location of the crossover line, it is advisable to consult a mechanic or refer to vehicle-specific documentation for more detailed information.
By checking for and understanding the crossover line in your fuel system, you can ensure proper equalization of fuel tanks and prevent issues such as overflow or uneven fuel distribution. This knowledge will help you make informed decisions when operating and maintaining your vehicle, boat, or other fuel-powered equipment.

Manually equalize fuel levels
Manually equalizing fuel levels in tanks can be done in several ways, depending on the setup of your tanks and the equipment available. Here are some methods to manually equalize fuel levels:
Firstly, if your tanks have a crossover or equalization valve, you can open this valve to allow fuel to transfer between the tanks and equalize the levels. If there is no crossover valve, consider installing one, as it will make equalizing fuel levels much easier.
If your tanks do not have a crossover valve, you can try "sticking" the tanks. This involves using a tool, such as a dowel or a stick, to manually measure the fuel levels in each tank. By dipping the stick into each tank, you can get a rough estimate of the fuel levels and determine if they are equal.
Another method is to inspect the boat's trim and change the fuel draw from one tank to another. You can do this by using a small pump to move the fuel between tanks, or by adjusting the fuel lines to draw from the tank with the most fuel. This method may require some trial and error, but it can effectively equalize the fuel levels.
Additionally, if your tanks have sight tubes or fuel level gauges, you can use them to monitor the fuel levels in each tank. By keeping track of the levels, you can make adjustments to the fuel distribution as needed to maintain equal levels.
Finally, if you have a single return system with no crossover valve, you may need to transfer weight or adjust the boat's trim to encourage the fuel to equalize. Once the levels are equal, ensure to maintain the balance by transferring weight or adjusting the trim as necessary.

Use a fuel equalizing system
Equalizing fuel tanks can be achieved by using a fuel equalizing system. This system is designed to balance the amount of fuel in multiple fuel tanks connected to a motor, such as a diesel engine in a truck, boat, or airplane. The system typically includes an equalization valve that connects the fuel tanks and controls the flow of fuel between them.
The equalization valve is a critical component of the fuel equalizing system. It features pressure-sensing elements that monitor the fuel pressure at the outlets of the tanks. When there is unequal fuel pressure, the valve actuator member responds by moving longitudinally to adjust the valve position and facilitate fuel transfer between the tanks. This mechanism ensures that the amount of fuel in each tank is equalized.
The valve also incorporates valve elements at its opposite ends, which play a crucial role in managing the flow of unused return fuel. These valve elements can be adjusted to control the spacing between each valve element and its associated stop, allowing for precise control over the return fuel flow. This feature ensures that the fuel is evenly distributed between the tanks.
In addition to the equalization valve, the fuel equalizing system may include additional components such as fuel pressure sensing elements, which can be spherical balls or O-rings made of elastomer material. These sensing elements are connected to the actuator member and play a vital role in detecting unequal fuel pressure, triggering the necessary adjustments by the valve actuator member.
By employing a fuel equalizing system, you can effectively equalize the fuel levels in multiple tanks. This system is particularly advantageous for vehicles with diesel engines, such as trucks, boats, or airplanes, where maintaining balanced fuel levels across multiple tanks is essential for optimal performance and fuel efficiency.

Monitor fuel levels
Monitoring fuel levels is crucial to ensure the effective equalization of fuel tanks. Here are some detailed instructions and considerations for this process:
Firstly, it is essential to understand the configuration of your fuel system. Check if your fuel tanks have sight tubes or a similar mechanism to visually inspect the fuel levels. If not, you may need to "stick" the tanks, which involves using a tool to manually check the fuel levels from the deck fill openings. This can provide a basic understanding of the fuel levels in each tank.
Additionally, pay attention to the behaviour of your vessel. Observe how the boat trims or lists to one side. An uneven fuel load can cause a noticeable list, indicating that equalization is required.
For boats with a single engine, two-tank, and one-return-line system, locating the crossover line is crucial. Usually, the builder would have included a crossover line to allow for equalization. Find this line and open the valve to facilitate the equalization process. Transferring weight or fuel can also help encourage equalization once the valve is open.
If your setup includes a genset, ensure it is not drawing fuel from one tank and returning it to another, as this can impact equalization.
In some cases, a small pump may be used to move fuel between tanks to achieve equalization. This can be done based on visual inspections, the behaviour of the vessel, or by regularly switching the fuel draw between tanks to maintain balance.
For dual propane tank setups, it is important to understand that only the gas will transfer between the tanks, not the liquid propane. Therefore, monitoring the fuel levels in each tank individually is crucial. Consider treating one tank as the primary source with automatic monitoring and the other as a reserve, manually monitored.
By diligently monitoring fuel levels and understanding your fuel system's intricacies, you can effectively equalize fuel tanks and ensure optimal performance.

Use a reserve tank
A reserve tank can be used as an emergency backup in case the main tank runs out of fuel or becomes unusable. This is particularly important for vehicles without a fuel gauge, or in situations where the operator may not be paying attention to the gauge, such as during inclement weather or other problems that may cause a diversion from the planned landing point. In such cases, the reserve fuel should be enough to reach a diversionary airfield.
In some cases, the reserve tank may be used to extend the range of a vehicle, especially aircraft, where increasing the capacity of the main tank is not possible due to weight and balance constraints. For example, some Airbus craft have an auxiliary fuel tank in the cargo hold, allowing for additional fuel to be carried safely.
For motorcycles and cars, the fuel reserve setting indicates a low level of fuel in the tank. In modern vehicles, this reserve fuel is automatically available when the main fuel is exhausted, and the engine will start sputtering. The rider or driver then has enough time to change a position knob, accessing the reserve fuel and preventing the engine from shutting down. In older motorcycles, a manual fuel tap or petcock is used instead. In most cases, the main and reserve settings draw from the same tank, but the reserve setting allows access to all the fuel, acting as a backup to ensure the rider can reach a petrol station.
When dealing with propane tanks, it is important to note that only gas will transfer between connected tanks, so liquid levels do not equalize. A valve can be installed between two tanks, allowing them to be filled and then closed off. One tank can be designated as the primary, with automatic monitoring, while the other serves as a reserve with manual monitoring. This setup provides the benefit of utilizing automatic monitoring while maximizing propane usage.
