Auxiliary Fuel Tanks: How Do They Work?

how do auxiliary fuel tanks work

Auxiliary fuel tanks are additional fuel storage systems that can be installed in vehicles to provide extended range and avoid the need for frequent refuelling. They are designed to supplement the existing fuel tank of a vehicle and are typically installed in the bed of a truck, providing extra fuel capacity for long hauls, RVing, or off-roading adventures. Auxiliary fuel tanks can be made from aluminium or steel and come in various sizes to fit specific needs, ranging from 37 to 100 gallons. They can be manually or automatically transferred to the main tank as needed, either through gravity-fed systems or electrical pump systems. These tanks offer convenience, reliability, and peace of mind, ensuring that vehicles won't run out of fuel in remote areas.

Auxiliary fuel tank installation

Auxiliary fuel tanks are a great way to ensure you don't run out of fuel on long-distance trips or in remote areas. They are also useful for avoiding fuel price gouging and saving money. If you're installing an auxiliary fuel tank, there are a few things to keep in mind.

First, ensure that you purchase a tank that is compatible with your vehicle. Tanks come in various sizes and materials, so choose one that fits your needs and your vehicle's specifications. For example, some tanks are designed to fit under a bed cover, while others are made specifically for certain truck models. It is also important to use an in-line pump to pump fuel from the auxiliary tank into the factory tank for gasoline auxiliary tank installations.

Next, consider the type of auxiliary tank you want. Some tanks have a small 12-volt pump, while others are gravity-fed. Gravity-fed tanks will keep refilling your main tank as long as there is fuel in the auxiliary, while electrical pump systems often have a switch that allows you to control when the stock tank is refilled. Most types come with a shut-off valve, allowing you to stop the tank from feeding your main tank if needed.

Finally, follow the installation instructions carefully to ensure the tank is securely installed and meets safety requirements. Proper installation will ensure that your auxiliary fuel tank provides you with the peace of mind and convenience it is designed for.

Benefits of auxiliary fuel tanks

Auxiliary fuel tanks are a great addition to any work truck, offering a range of benefits for those who frequently travel long distances or work in remote areas.

One of the most significant advantages is the extended range they provide. Auxiliary tanks increase the fuel capacity of your truck, allowing you to cover longer distances without worrying about running out of fuel. This is especially useful for long hauls on desolate roads, where refuelling options may be limited. With an auxiliary tank, you can avoid the stress of constantly monitoring your fuel levels and worrying about finding a gas station at the last minute.

Additionally, auxiliary fuel tanks offer flexibility and convenience when it comes to refuelling. They enable you to be more selective about when and where you stop for fuel. You can choose to refuel at gas stations with better prices and avoid the higher prices often found at remote stations with less competition. This can result in significant cost savings over time.

Auxiliary fuel tanks also enhance safety and security. Storing extra fuel in a proper auxiliary tank is much safer than using plastic containers, which can be hazardous if not properly secured in the truck bed. There is a reduced risk of accidents, fuel spills, or theft, which is a common concern with plastic containers. Furthermore, auxiliary tanks made from high-quality, heavy-duty materials meet official safety requirements for combustible fuel tanks, providing peace of mind while on the road.

Some auxiliary tank designs also offer additional functionality, such as the auxiliary tank toolbox combo. This combination provides a convenient storage solution for both tools and extra fuel, saving space and adding practicality for truck owners.

Auxiliary fuel tank safety

Auxiliary fuel tanks are a great way to ensure good fuel levels without the hassle of frequent refuelling. They are especially useful for long-distance travel, multiple job sites in a day, or trips to remote areas with few fuel stations. These tanks can be hooked up to a generator, motorcycle, boat, ATV, or other recreational vehicles. They are also beneficial for saving money on fuel, as you can fill up at cheaper locations and avoid price gouging in remote areas.

However, there are several safety considerations to keep in mind when using auxiliary fuel tanks. Firstly, always opt for a proper auxiliary fuel tank installed in your vehicle instead of carrying plastic containers of extra fuel. Plastic containers can lead to accidents, spills, or theft if not properly secured. Additionally, the fumes from these containers can cause health issues and impair your driving ability.

When choosing an auxiliary fuel tank, ensure that it meets the official safety requirements for combustible fuel tanks. Look for tanks that are made from high-quality, heavy-duty materials. Some tanks are designed to meet and exceed safety standards, such as Title 49 CFR 393.65 for fuel tanks in the United States.

Another safety feature to consider is a shut-off valve, which allows you to stop the flow of fuel from the auxiliary tank to the main tank. This is particularly important for electrical pump systems to prevent overfilling. For example, Transfer Flow's auxiliary fuel tank systems include a shut-off valve and are designed to meet or exceed safety standards.

Finally, consider additional safety features offered by some manufacturers, such as lockable lids or fuel caps, which provide added security for your auxiliary fuel tank and prevent unauthorized access. These features can give you peace of mind and ensure the safe use of your auxiliary fuel tank.

Auxiliary fuel tank sizes

Auxiliary fuel tanks come in a range of sizes to suit different vehicles and needs. The size of the tank will depend on the make and model of the vehicle, as well as the available space for installation. Tanks are available in various capacities, commonly ranging from 30 to 100 gallons.

For example, KSH Fuel Products offers auxiliary fuel tanks in sizes of 30, 50, 70, and 100 gallons, compatible with various models of Chevy, Dodge, Ford, GM, and Ram Trucks. Transfer Flow Inc. offers a similar range, with tanks of 37, 40, 50, 75, and 100 gallons, designed for diesel trucks.

The shape of the auxiliary fuel tank also varies, with rectangular, wedge, and L-shaped tanks available. The wedge-style tanks, for instance, are designed for full-size Dodge, Ford, and GM diesel trucks, while the L-shaped tanks are for long-bed diesel trucks.

The size of the auxiliary fuel tank is an important consideration, as it determines the additional fuel capacity and, consequently, the extended driving range. A larger tank can provide peace of mind, especially on long-distance trips, by reducing the frequency of refuelling stops. It can also save money, as it allows drivers to avoid refuelling at expensive truck stops or in areas with higher fuel prices.

Overall, the size of the auxiliary fuel tank is a key factor in its functionality and benefits, providing convenience, cost savings, and improved fuel management for vehicle owners.
