It not only allows me to go on longer trips without the constant worry of running out of fuel, but also gives me the flexibility to explore off-the-grid areas. After trying out various options, I have put together this buying guide to help you make an informed decision when purchasing an auxiliary fuel tank cap.
Why do you need an Auxiliary Fuel Tank Cap?
An auxiliary fuel tank cap is a must-have for anyone who loves to travel long distances or go off-roading. It is a secondary fuel tank that connects to your vehicle’s main tank, providing additional fuel storage capacity. This means you can travel longer distances without having to stop for refueling. It also comes in handy in emergency situations where gas stations are not easily accessible.
Consider the Capacity
The first thing you need to consider when buying an auxiliary fuel tank cap is its capacity. This will depend on your personal needs and the type of vehicle you have. Some tanks can hold as little as 5 gallons while others can hold up to 50 gallons or more. Keep in mind that the larger the capacity, the heavier it will be and it may affect your vehicle’s gas mileage.
Type of Material
Auxiliary fuel tanks are typically made of either aluminum or plastic. Aluminum tanks are more durable and can withstand extreme weather conditions, but they tend to be heavier and more expensive. Plastic tanks are lightweight and affordable, but they may not be as durable as aluminum ones.
Installation Process
Before making a purchase, it is important to consider how easy or difficult it will be to install the auxiliary fuel tank cap on your vehicle. Some tanks require professional installation while others come with simple DIY instructions. Make sure you choose one that fits your level of expertise and budget.
Compatibility with Your Vehicle
Not all auxiliary fuel tank caps are compatible with every type of vehicle. Before making a purchase, make sure that the one you choose is specifically designed for your make and model of vehicle. This will ensure proper fitment and functionality.
Additional Features
Some auxiliary fuel tanks come with additional features such as a built-in pump or gauge for easy monitoring of fuel levels. While these features may come at an additional cost, they can be extremely convenient and worth the investment.
Budget
Last but not least, consider your budget when purchasing an auxiliary fuel tank cap. Prices vary depending on size, material, and additional features. Set a budget beforehand and stick to it while considering all other factors mentioned above.
In Conclusion
An auxiliary fuel tank cap is a valuable addition to any vehicle owner who loves adventure and long-distance travel. By considering factors such as capacity, material, installation process, compatibility, additional features, and budget, you can find the perfect auxiliary fuel tank cap for your needs.
