An aft-axle fuel tank is an auxiliary fuel tank that can be added to a truck to increase its fuel capacity. They are often added to trucks with diesel engines, such as the Ford F-Series Super Duty trucks and the Silverado Sierra. The tanks are typically made of steel or plastic and are mounted on the truck's frame, either behind the axle or in the spare tire area. Some owners opt to install them to avoid sacrificing bed and toolbox space.

What You'll Learn
Ford F450/550 vehicles with steel aft axle tanks
An aft-axle fuel tank is an additional fuel tank that can be installed at the rear of a vehicle. Some Ford F450 and F550 Super Duty vehicles with diesel and gas V8 and V10 engines, manufactured between 1999 and 2010, featured steel aft-axle fuel tanks. Ford employed a metallic liner on the inside of these tanks to prevent rust. However, prolonged exposure to low-sulphur diesel caused the liner to peel away, leading to potential fuel system issues.
Ford F450/550 owners have considered various options to enhance fuel capacity. One popular suggestion involves replacing the standard midship fuel tank with a larger capacity tank, such as the Transfer Flow 57-gallon option. Another option is to add an auxiliary fuel tank, such as the Titan 4020217 40-gallon aft-axle tank, compatible with 2017-2022 Ford F-450/550 models. This tank can be purchased from suppliers like XDP, which offers competitive pricing and fitment verification for a guaranteed installation match.
Some Ford enthusiasts have contemplated installing an Excursion aft-axle fuel tank on their F450/550 Super Duty trucks. This modification aims to increase fuel capacity without sacrificing bed and toolbox space. However, it raises concerns about the structural integrity of the frame, particularly regarding the removal of the spare tire x-member. While some owners suggest that removing this cross-member is feasible, others worry about potential negative impacts on the rear structurability of the frame.
It is important to carefully consider any modifications to your vehicle, especially when it comes to fuel tanks and the fuel system. Always consult with qualified professionals and adhere to safety guidelines to ensure that any alterations are safe and compliant with relevant regulations.

Fuel tank rust issues
An aft-axle fuel tank is an auxiliary fuel tank that can be added to specific Ford truck models, such as the F-350, F-450, and F-550 Super Duty trucks. This option is often considered by owners who want to increase their vehicle's fuel capacity without sacrificing bed and toolbox space.
Now, fuel tank rust issues are a common problem, especially in older vehicles and classic cars. While rust on exterior panels is easy to spot, fuel tank rust is a more subtle issue. Here are some key points regarding fuel tank rust:
Causes of Fuel Tank Rust
The primary cause of fuel tank rust is moisture. The more moisture your tank comes into contact with, the more likely it is to develop severe rust over time. Environmental factors, such as road salt and humidity, can accelerate the oxidation process. Road salt, in particular, speeds up rusting as it allows salty water to form and oxidation to occur more rapidly. High humidity also increases the risk of water entering the tank, which then settles at the bottom and promotes oxidation.
In addition to environmental factors, fuel quality can also contribute to tank rust. Moisture can enter the fuel tank due to contaminated gas or a loose fuel filler cap.
Signs of a Rusty Fuel Tank
The most obvious sign of a rusty fuel tank is a strong smell of gasoline. However, this is an extreme symptom that indicates the tank has already failed. Rust can cause issues long before it creates holes in the tank. For example, rust flakes can break off and clog the fuel filter, damaging fuel injectors and leading to a lean running condition as insufficient fuel reaches the engine's combustion chamber.
Addressing Rust Issues
The first step in addressing rust is recognizing its presence. If you own an older vehicle or a classic car, it is crucial to have your tank periodically inspected for rust problems. Once rust is discovered, it should not be ignored. Depending on the severity, you may need to replace the fuel tank entirely. For less severe cases, welding a patch or properly cleaning the interior of the tank may be sufficient.

Plastic replacement tanks
An aft-axle fuel tank is an additional fuel tank that can be installed at the rear of a truck, providing greater fuel capacity without taking up bed or toolbox space.
If you're looking for a plastic replacement tank, there are a few options to consider. Firstly, it's important to note that plastic replacement tanks may not offer the same durability as steel tanks, but they can still be a good option for certain vehicles and use cases.
For example, Raybuck offers Jeep polyethylene replacement gas tanks designed to withstand the demands of off-roading and everyday driving. These tanks are a more affordable alternative to OEM products, offering comparable performance at a more reasonable price.
Transfer Flow also provides replacement fuel tank systems made from aluminized steel, which offer superior durability and strength compared to plastic tanks. Their tanks are baffled to reduce fuel sloshing during acceleration, braking, and cornering, resulting in a safer and more stable driving experience.
If you own a Ford F-350/450/550, you might consider the Titan 4020217 40-gallon aft-axle auxiliary fuel tank, which can be added to models from 2017 to 2022.
When considering a plastic replacement tank, it's important to research the compatibility, durability, and safety features to ensure it meets your specific needs and vehicle requirements.
