Some Factors You Should Know About Auxiliary Fuel Transfer Tanks

Introduction

Auxiliary fuel transfer tanks are a great addition to any vehicle, providing extra fuel storage and the ability to refuel without the need to stop at a gas station. However, choosing the right one can be a daunting task, as there are many different options available on the market. In this article, we will provide some tips and guidance on how to choose the best auxiliary fuel transfer tank for your needs.

Considerations

Before making a purchase, there are a few key considerations to keep in mind. These include the size of the tank, the type of fuel it can hold, and the compatibility with your vehicle.

First and foremost, you need to consider the size of the tank. Auxiliary fuel transfer tanks come in a range of sizes, from small tanks that can hold just a few gallons of fuel, to large tanks that can hold upwards of 100 gallons. The size you choose will depend on your specific needs, such as how far you plan to travel and how much extra fuel you want to carry.

Next, you need to consider the type of fuel the tank can hold. Most tanks are designed to hold gasoline or diesel, but there are also options available for other fuels such as kerosene, biofuels, and even water. Be sure to choose a tank that is compatible with the type of fuel your vehicle uses.

Finally, you need to consider the compatibility of the tank with your vehicle. This includes factors such as the size and shape of the tank, as well as the location where it will be installed. Some tanks are designed to fit in specific locations, such as the bed of a pickup truck, while others are more versatile and can be mounted in a variety of locations. Be sure to choose a tank that will fit securely and safely on your vehicle.

Features

In addition to the basic considerations outlined above, there are also a few key features to look for in an auxiliary fuel transfer tank. These include the construction material, the type of pump, and the presence of any additional features such as a fuel gauge or a locking cap.

The construction material is an important factor to consider, as it will determine the durability and longevity of the tank. Most tanks are made of metal, such as aluminum or steel, but there are also options available in plastic or other materials. Aluminum tanks are generally the most lightweight and durable, making them a good choice for most applications.

The type of pump is also an important consideration, as it will determine how easy it is to transfer fuel from the tank to your vehicle. Most tanks come with a simple hand pump, which can be used to transfer fuel manually. However, there are also options available with electric or battery-powered pumps, which can make the process much easier and faster.

Finally, consider any additional features that may be useful, such as a fuel gauge or a locking cap. A fuel gauge can help you keep track of how much fuel is left in the tank, while a locking cap can help prevent unauthorized access to the fuel.

Conclusion

In conclusion, choosing the right auxiliary fuel transfer tank is an important decision that can greatly impact the convenience and functionality of your vehicle. By considering the size, fuel type, compatibility, construction material, pump type, and additional features, you can find the perfect tank for your needs. With the right auxiliary fuel transfer tank, you can enjoy the convenience of extra fuel storage and the ability to refuel on the go.

Frequently Asked Questions (FAQs)

1. Are auxiliary fuel tanks worth it?

Yes, auxiliary fuel tanks are worth it as they provide several benefits. They can save you from running out of fuel at inconvenient times and reduce the number of stops you have to make. This gives you the freedom to choose when and where to refuel, allowing for more convenience and flexibility during your journeys.

2. What size are auxiliary fuel tanks?

Auxiliary fuel tanks come in various sizes, starting from 30 gallons and going up to 110 gallons. There are different designs available, including rectangle, L-shaped, wedge, and low profiles. One popular style is the under toolbox auxiliary fuel tanks, which have a lower height to fit under a toolbox.

3. How many gallons of diesel can I transport?

When transporting diesel fuel, it is important to note that the maximum amount allowed is 500 gallons at a time. This regulation ensures safe handling and transportation of diesel fuel.

4. What are the 3 types of fuel tank?

The three main types of fuel storage options are integral, bladder, and rigid removable fuel tanks. These options offer different advantages and considerations in terms of design, installation, and usage.

5. Is a half tank better than a full tank for fuel economy?

For fuel economy, there is little difference between a half tank and a full tank. Filling up a tank halfway only reduces the weight by around 2.5%, which has minimal impact on fuel efficiency. It is generally recommended to fill the tank all the way to the top to maximize the distance you can travel before needing to refuel.

6. What is the disadvantage of bladder fuel tank?

One disadvantage of a bladder fuel tank is the limited available fuel volume. Bladder tanks are made by placing a shaped rubber bag into a cavity in the aircraft structure. However, the thickness of the rubber bag reduces the overall fuel capacity of the tank.

7. How thick should a fuel tank be?

The material thickness of a fuel tank is important for durability. It is recommended to insist on a minimum thickness of 1/8 inch for aluminum tanks, 12 gauge steel, or 14 gauge stainless steel. This ensures a strong and reliable fuel tank that can withstand the demands of transportation and usage.
