Types of Auxiliary Fuel Tanks
1. In-Bed Auxiliary Fuel Tanks
In-bed auxiliary fuel tanks are designed to fit within the truck bed, maximizing space without hindering functionality. These tanks typically range from 37 to 100 gallons in capacity and are constructed from durable materials like aluminized steel or aluminum. They often feature an auto-transfer system, ensuring a seamless fuel transfer from the auxiliary tank to the main fuel tank during operation.
2. Toolbox Combo Tanks
Toolbox combo tanks combine fuel storage with a toolbox, providing a dual-purpose solution. These tanks often come with integrated security features, such as lockable lids, to protect both fuel and tools. They are particularly popular among contractors and outdoor enthusiasts who need both space for tools and extra fuel.
3. Low Profile Tanks
Low profile tanks are specifically designed for truck beds with limited height. They sit below the bed rails, allowing for compatibility with truck bed covers. This design is ideal for those who want to maintain the aesthetics of their truck while maximizing fuel storage capacity.
Applications of Auxiliary Fuel Tanks
1. Long-Distance Travel
For long hauls, an auxiliary fuel tank can significantly extend your driving range. This is especially useful for truck drivers who travel through remote areas where fuel stations are scarce. Brands like Transfer Flow offer systems that automatically transfer fuel, ensuring that you never run out during your journey.
2. Off-Roading Adventures
Off-roading can be exhilarating, but it often leads to long distances between fuel stops. Having an auxiliary fuel tank allows you to explore more without the worry of running low on fuel. This is a common application for trucks equipped with tanks from companies like ATI Tank and RDS Aluminum.
3. Emergency Preparedness
In emergency situations, having a reliable source of fuel can be critical. Auxiliary fuel tanks provide peace of mind, ensuring that you are always prepared for unexpected scenarios. Whether for natural disasters or mechanical failures, these tanks can be a lifesaver.
Key Features to Consider
When selecting an auxiliary fuel tank, consider the following features:
1. Material
The construction material of the tank is crucial for durability and weight. Most tanks are made from either aluminized steel or aluminum. While steel provides strength, aluminum offers a lighter weight, which can be beneficial for performance.
2. Transfer System
Look for tanks with automatic transfer systems, such as the TRAX 4™ from Transfer Flow. These systems ensure smooth and efficient fuel transfers without manual intervention, reducing the risk of spills and increasing convenience.
3. Installation
Installation complexity varies between models. Some tanks come with easy-to-use installation kits, while others may require professional installation. Ensure that the chosen tank has clear instructions for installation, such as those offered by ATI Tank.
4. Security Features
For those who prioritize security, choosing a tank with lockable features is essential. Toolbox combo tanks, like those from RDS Aluminum, often provide enhanced security for both fuel and tools.
