What is a Spare Tire Fuel Tank?
A spare tire fuel tank is an aftermarket auxiliary fuel reservoir designed to integrate with a vehicle, often replacing or supplementing the standard spare tire mounting location. These tanks significantly increase a vehicle's total fuel capacity, allowing for extended travel distances without frequent refueling stops. They are particularly popular among RV owners, expedition vehicle builders, and off-road enthusiasts who require greater autonomy and range.
- Increases total vehicle fuel capacity.
- Mounts in spare tire location.
- Enhances travel range significantly.
- Targeted for RVs and off-road vehicles.
The core principle is simple: more fuel equals more miles. This setup is not a factory option for most vehicles but is a strategic modification for specific user needs. Understanding its purpose is the first step to appreciating its utility.
Purpose and Functionality
The primary function of a spare tire fuel tank is to provide an additional fuel source, effectively extending the vehicle's operational range. This is crucial for scenarios where fuel stations are scarce or for prolonged journeys where convenience is paramount. The tank is engineered to safely store gasoline or diesel, depending on the vehicle's requirements and the tank's specifications.
This mechanism is critical for adventurers who push their vehicles into remote terrains.
Types of Spare Tire Fuel Tanks
These tanks generally come in two main configurations: those that mount *in place of* the spare tire, and those that mount *alongside* it, often on a custom bracket. Some specialized systems might integrate fuel transfer pumps and control modules, allowing drivers to switch between primary and auxiliary tanks seamlessly.

It is imperative to acknowledge that such modifications require professional installation to ensure safety and compliance with local regulations.
Why Choose an Auxiliary Fuel Tank for Your Vehicle?
Why would you opt for a spare tire fuel tank? The most compelling reason is the substantial increase in your vehicle's range. Imagine driving cross-country or exploring remote off-road trails without the constant anxiety of finding the next gas station. This added capacity liberates you from predetermined routes and offers peace of mind.
Extended Range for RVs and Expedition Vehicles
For RV owners, a spare tire fuel tank can mean the difference between a leisurely journey and a stressful one. It provides the flexibility to travel to more secluded campsites or to take advantage of lower fuel prices further afield. Similarly, expedition vehicles venturing into undeveloped areas benefit immensely, ensuring they can reach their destination and return safely.
The primary consideration involves planning for longer-duration trips.
This system is a practical solution for anyone prioritizing freedom of movement over frequent stops.
Cost Savings and Convenience
Beyond just range, these tanks can facilitate cost savings. By allowing you to fill up when fuel prices are lowest, regardless of your current location, you can optimize your expenditure. The sheer convenience of fewer stops also translates into more time enjoying your journey and less time waiting at the pump.
The strategic advantage of increased fuel capacity is unparalleled for independent travel.
Such precision is paramount for uninterrupted exploration.
The secondary benefit is the reduction in overall travel time, as fewer refueling stops are necessary.
Installing and Maintaining Your Spare Tire Fuel Tank
Considering a spare tire fuel tank means understanding the installation process and ongoing maintenance requirements. While the concept is straightforward, proper setup is crucial for safety and functionality. Most systems are designed for specific vehicle types, like a utility trailer spare tire mount or a specific UTV spare tire mount, ensuring a relatively good fit.
Installation Considerations
Professional installation is highly recommended. Certified mechanics or specialized off-road shops have the expertise to correctly mount the tank, plumb the fuel lines, and integrate any necessary control systems. This includes ensuring the tank is securely fastened and protected from road debris, and that all connections are leak-proof. For example, a spare tire boat trailer mount requires robust securing to withstand marine environments, and a fuel tank demands even greater diligence.
A common mistake is underestimating the complexity of fuel line routing and venting.
Verify local regulations before installation, as some areas have strict rules regarding auxiliary fuel tank capacity and placement.
Maintenance Best Practices
Regular maintenance is key to the longevity and safety of your spare tire fuel tank. This includes periodic inspections for leaks, damage, or corrosion. Check fuel lines, connections, and the tank itself for any signs of wear or compromise. If the tank is for diesel, ensure the fuel remains fresh to prevent microbial growth. For gasoline tanks, periodically check the venting system to prevent pressure build-up.
Understanding this principle is fundamental to safe operation.
Regularly inspect the spare tire hanger for trailer or RV to ensure it remains structurally sound, especially if it's integrated with fuel tank mounting.
Troubleshooting Common Issues
Should you encounter issues, start with the simplest checks: Is the fuel pump running? Are the fuel lines unobstructed? Is the venting system clear? If the tank is not filling or emptying correctly, it often points to a blockage or a problem with the pump or valve system. A faint fuel smell might indicate a minor leak that requires immediate attention.
