Fuel Tanks: Are They Swappable Between Trucks?

are fuel tanks interchangable between different trucks

Fuel tank interchangeability is a topic that has been widely discussed in truck forums. The consensus is that while some fuel tanks may be interchangeable between different trucks, it depends on several factors, including the truck model, the fuel tank specifications, and the compatibility of the hangers, straps, and brackets. In some cases, aftermarket fuel tanks from companies like Titan or TransferFlow may be required for larger fuel capacities, which can be a costly investment. Additionally, considerations about the fuel pump and engine performance come into play when modifying fuel tanks.

Fuel tank hangers

It is worth noting that fuel tank hangers are not limited to trucks alone. They are also available for other vehicles, including cars, SUVs, and vintage vehicles.

In addition to fuel tank hangers, there are other components that may require attention when dealing with fuel tanks. For instance, the sending unit, which is responsible for fuel gauge readings, can vary between different tank sizes. Adjustable float arms can compensate for these differences, ensuring compatibility between sending units and fuel tanks of various capacities.

When considering fuel tank modifications, it is essential to prioritize safety. Always refer to reliable sources and consult experts when in doubt to ensure that any changes made to your vehicle's fuel tank system comply with safety standards and regulations.

Tank diameter

Fuel tanks are generally interchangeable, but the compatibility of a fuel tank depends on the truck's make and model. For example, a 2011 4x4 F350 shortbed truck with a 26-gallon fuel tank can be replaced with a 35-gallon tank or a 38-gallon tank from newer models. However, some trucks may require aftermarket options, such as Titan or TransferFlow, if compatible stock tanks are unavailable.

The diameter of a fuel tank is an important factor in determining compatibility. Trucks with different frame sizes may require fuel tanks of specific diameters to fit properly. For instance, a user with a Kenworth K100 truck inquired about replacing the short fuel tanks with longer, skinnier tanks after stretching the frame.

Fuel tank trucks, or tankers, used for transporting large volumes of fuel, come in various sizes and capacities. These tankers often have an oval or elliptical cross-section with rounded ends and multiple compartments. The capacity of a fuel tank truck can range from 3,500 gallons for a bobtail tanker to 11,500 gallons for highway transporters, with "supertankers" capable of carrying up to 11,600 gallons.

The size and capacity of fuel tanks also vary depending on the truck's segment, such as the number of wheels and its intended use. For example, 10-wheeler trucks typically have fuel tank capacities ranging from 200 to 400 litres, while 12-wheeler trucks used for continuous haulage operations can have fuel tank capacities from 300 to 500 litres. 18-wheeler trucks, on the other hand, usually have larger fuel tanks, ranging from 400 to 600 litres, to accommodate long-distance haulage without frequent refuelling.

Aftermarket tanks

Aftermarket fuel tanks are a popular option for truckers looking to increase their fuel capacity and extend their range. These tanks are designed to address the limitations of factory-equipped fuel tanks, which often have smaller capacities that require frequent refuelling.

Transfer Flow also offers top-quality aftermarket fuel tank systems that provide an extended driving range. Their tanks are made from 12- and 14-gauge aluminized steel, providing superior durability and strength. Additionally, their tanks are fully baffled to reduce fuel sloshing during acceleration, braking, and cornering, resulting in a safer and more stable driving experience.

The availability of aftermarket tanks allows truck owners to be more selective about when and where they stop for fuel. While these tanks can be pricey, often costing over $1000, they can be a worthwhile investment for those who travel frequently.

It is important to note that the compatibility of aftermarket tanks may vary between different truck models and years. Therefore, it is essential to research and consult with experts to ensure that the selected aftermarket tank is compatible with the specific truck make and model.

Strap parts

Fuel tanks in trucks can be interchangeable, but the hangers may differ between truck models. If the fuel tank diameter is different, the strap part from another truck model may be used. These strap parts are essential for securing the fuel tank in place, preventing it from shifting or sagging during long hauls.

Fuel tank straps, also known as fuel tank bands, are designed to securely hold the fuel tank in place beneath the truck. They are typically made of durable materials such as carbon-based steel, stainless steel, or aluminium. The width, thickness, and bolt size of these straps vary depending on the truck model and fuel tank size. For example, fuel tank straps for Freightliner trucks have a width of 1 3/4 inches and a thickness of 3 mm, while those for Peterbilt trucks may have a width of 3-7/10 inches and a thickness of 5 mm.

The installation process for fuel tank straps can vary, but some straps offer simple and easy installation, such as those designed for Freightliner M2-106/112 Business Class trucks. These straps feature a step-bracket design and are adjustable to ensure a secure fit. The bolts used with these straps are typically made of strong materials, such as stainless steel, and may have special features like T-bolts or T-screw bolts for a stronger connection.

When choosing fuel tank straps, it is important to consider the size and shape of the fuel tank, as well as the specific truck model. Some straps are designed for specific fuel tank sizes, such as those made for 24-inch or 26-inch fuel tanks. Additionally, some straps are compatible with specific truck models, like the straps designed for the 2009-2011 Peterbilt truck models or the 1987-2011 Kenworth truck models. It is crucial to select the appropriate strap to ensure the fuel tank's stability and safety.

In some cases, aftermarket fuel tank straps may be required. These straps are designed to fit specific truck models and fuel tank sizes, offering a more customised solution. Aftermarket straps can be purchased from companies like Parts Synergy, Inc., and are often made to withstand specific conditions, such as cold temperatures. It is recommended to consult a professional or refer to the truck's manual to ensure the correct fuel tank strap is selected and installed properly.

Float arms

While it is difficult to definitively state whether fuel tanks are interchangeable between different trucks, some online sources suggest that the tanks themselves may be interchangeable, but the hangers may differ between truck models. However, it is important to note that there are no stock tanks that are interchangeable, and one might have to opt for aftermarket options.

Now, moving on to the topic of float arms, they are an essential component in fuel level monitoring systems, particularly in mechanical setups. Float arms are typically made of stainless steel and designed with either one or two floats, depending on the layout of the fuel tank. These floats ride on the surface of the fuel, providing critical information about the fuel level.

The function of float arms is straightforward yet ingenious. They are attached to a pivot point, allowing them to move up and down as the fuel level rises and falls. This motion is then translated into a signal or indication that reflects the amount of fuel in the tank. The beauty of float arms lies in their adjustability, ensuring compatibility across different tanks and gauges.

Rochester Sensors, a company specialising in sensors and monitoring solutions, offers a range of float arm options for fuel level monitoring. Their offerings include mechanical float arms for horizontal cylindrical farm tanks or tanks with flat heads. These float arms are equipped with a Bulls Eye Gauge that provides high, normal, and low liquid level indications for effective fuel management.

In conclusion, while the interchangeability of fuel tanks between trucks remains a complex question, float arms play a pivotal role in fuel level monitoring. With their adjustable design, float arms ensure compatibility across different tank configurations, making them a versatile solution for accurate fuel level measurements.
