Warning: Proper Use of Auxiliary Tanks To ensure safety and optimal performance, do not fill your auxiliary tank to 100% capacity. Auxiliary Tanks require sufficient headspace to allow for fuel expansion and vapor buildup. Overfilling the tank can lead to: Fuel Leaks: Excess fuel may escape through vents or seals, posing safety and environmental risks. Increased Pressure: Without adequate space for vapor, pressure buildup can damage the tank or connected systems. Compliance Issues: Overfilled tanks may violate local or federal regulations for fuel transport. Safe Filling Recommendations Fill the tank to 90% of its capacity to allow room for fuel expansion. Use proper venting systems and check all connections for leaks before transport. Follow all local, state, and federal guidelines for the storage and transport of fuel. By adhering to these precautions, you can ensure the safe and reliable use of your transfer tank while protecting your vehicle, environment, and compliance with regulations.
