Running out of fuel in the middle of nowhere is a truck driver's nightmare. Whether you're hauling freight across state lines, navigating remote job sites, or embarking on an extended off-road adventure, a reliable fuel supply is paramount. That's where a truck auxiliary gas tank comes in. These supplementary fuel storage solutions can significantly extend your vehicle's range, offering peace of mind, increased efficiency, and greater flexibility for your travels. This comprehensive guide will delve into everything you need to know about truck auxiliary gas tanks, from understanding their benefits to choosing the right one for your needs and ensuring a safe and compliant installation.
Why Consider an Auxiliary Gas Tank for Your Truck?
Truck Auxiliary Gas Tanks: Extend Your Range and Conquer the Road
Auxiliary gas tanks aren't just for long-haul truckers. They offer a multitude of benefits for various truck owners:
- Extended Range: The most obvious advantage is the ability to travel much farther between fuel stops. This is crucial for long trips, remote locations with limited fuel availability, and situations where you want to avoid price gouging at certain gas stations.
- Time Savings: Fewer fuel stops mean less time spent filling up and more time on the road, translating to increased productivity and efficiency, especially for commercial drivers.
- Fuel Cost Savings: You can strategically fill up at locations with lower fuel prices and avoid costly emergency fill-ups in inconvenient locations.
- Convenience and Peace of Mind: Knowing you have a reserve fuel supply eliminates the anxiety of running low, particularly in unpredictable situations like unexpected detours, traffic jams, or inclement weather.
- Off-Road Adventures: For off-road enthusiasts, auxiliary tanks are essential for exploring remote trails and backcountry areas where gas stations are nonexistent.
- Reduced Wear and Tear: By avoiding frequent stops and starts, you can potentially reduce wear and tear on your vehicle's engine and transmission.

Understanding the Components and Functionality
A typical auxiliary gas tank system consists of the following key components:
- The Tank: Usually constructed from durable materials like aluminum or steel, the tank comes in various sizes and shapes to fit different truck models and space constraints.
- Fuel Transfer System: This system allows fuel to be transferred from the auxiliary tank to the main fuel tank. There are two primary types:
- Gravity-Fed Systems: These are the simplest and most affordable. They rely on gravity to transfer fuel when the auxiliary tank is positioned higher than the main tank. A valve controls the flow.
- Electric Pump Systems: These systems use an electric pump to actively transfer fuel, offering more control and allowing for tank placement at the same level or even lower than the main tank.
- Fuel Lines: These hoses connect the tanks and transfer system, ensuring a leak-proof and secure connection.
- Fuel Filter: This filter prevents contaminants from the auxiliary tank from entering the main fuel system.
- Venting System: This system allows air to escape the tank as it's filled and prevents pressure buildup during temperature fluctuations.
- Monitoring System (Optional): Some systems include gauges or sensors to monitor fuel levels in both tanks.
- Installation Hardware: Brackets, straps, and other hardware are required to securely mount the tank to the truck frame.
Choosing the Right Auxiliary Gas Tank: Key Considerations
Selecting the appropriate auxiliary gas tank requires careful consideration of your specific needs and vehicle:
- Tank Capacity: Determine the desired range extension based on your typical travel patterns and fuel consumption. Consider the size and weight limitations of your truck.
- Tank Material: Aluminum tanks are lighter and more corrosion-resistant, while steel tanks are generally more durable and affordable.
- Transfer System: Choose between gravity-fed and electric pump systems based on your budget, installation requirements, and desired level of control.
- Tank Shape and Size: Measure the available space in your truck bed or chassis to ensure a proper fit. Consider tanks that are designed to fit specific truck models.
- Fuel Type: Ensure the tank and transfer system are compatible with the type of fuel your truck uses (gasoline or diesel).
- Safety Features: Look for tanks that meet industry safety standards and include features like rollover valves and pressure relief valves.
- Manufacturer Reputation: Choose a reputable manufacturer with a proven track record of quality and reliability.
- Compliance with Regulations: Ensure the tank meets all applicable federal, state, and local regulations regarding fuel storage and transportation.
- Budget: Auxiliary gas tank systems range in price, so set a budget and compare different options within your price range.
Installation: A Step-by-Step Overview (Professional Installation Recommended)
While some experienced mechanics may attempt a DIY installation, professional installation is strongly recommended to ensure safety, compliance, and proper functionality. However, understanding the general process is beneficial:
- Planning and Preparation: Carefully review the manufacturer's instructions and gather all necessary tools and materials.
- Tank Mounting: Securely mount the tank to the truck frame using the provided brackets and hardware. Ensure the tank is properly supported and protected from damage.
- Fuel Line Connections: Connect the fuel lines between the auxiliary tank, transfer system, and main fuel tank. Ensure all connections are tight and leak-proof.
- Electrical Wiring (for Electric Pump Systems): Connect the electric pump to the truck's electrical system, following the manufacturer's wiring diagram.
- Venting System Installation: Install the venting system to allow for proper air circulation and pressure relief.
- Fuel Filter Installation: Install the fuel filter to protect the fuel system from contaminants.
- Testing and Inspection: After installation, thoroughly inspect all connections for leaks and test the transfer system to ensure it is functioning correctly.
Important Considerations and Safety Precautions
- Professional Installation: As mentioned earlier, professional installation is highly recommended to ensure safety and compliance.
- Fuel Spillage: Handle fuel with care to avoid spills and contamination. Use appropriate safety equipment, such as gloves and eye protection.
