Tank location: Tanks are typically found on both the driver and passenger sides
The Freightliner Cascadia is a semi truck with fuel tanks typically found on both the driver and passenger sides. These tanks are made of high-quality, rugged aluminium and offer a range of capacities, from 100 gallons to 150 gallons.
The location of the fuel tank on a Freightliner Cascadia is an important consideration for owners and operators of these vehicles. The tanks are usually positioned on both sides of the truck, providing a balanced weight distribution and ensuring easy access for refuelling.
The driver's side fuel tank is often referred to as the primary tank, and it is generally the first tank to be filled during refuelling. This tank is conveniently located near the driver, allowing for easy monitoring of fuel levels and access to the fuel cap. On some Freightliner Cascadia models, the driver's side tank may be the only fuel tank, providing a simpler fuel system design.
The passenger side fuel tank is also an important component of the Freightliner Cascadia's fuel system. This tank is located on the opposite side of the truck, providing additional fuel capacity and balance to the vehicle. The passenger side tank can be filled independently or, in some cases, fuel can be transferred between the tanks to ensure a consistent fuel level and weight distribution.
The fuel tanks on the Freightliner Cascadia are designed to provide sufficient capacity for long-haul journeys, reducing the need for frequent refuelling stops. The tanks are durable and efficient, ensuring that the truck can reliably cover long distances without fuel-related issues.

Fuel transfer: Fuel can be transferred between tanks via a cross feed
The Freightliner Cascadia is a heavy-duty truck with large fuel tanks—they range from 100 gallons to 150 gallons in capacity. The truck typically has two fuel tanks, and fuel is drawn from both tanks simultaneously and equally.
Fuel Transfer
Fuel can be transferred between tanks via a cross feed. This is a mechanism that allows fuel to be drawn from one tank and transferred to the other, ensuring that both tanks remain at the same level. This is important because it prevents the truck from running out of fuel in one tank before the other, which could cause issues with the fuel system and engine performance.
The cross feed system is usually gravity-fed, meaning that fuel flows from one tank to the other due to the force of gravity. However, in some cases, an air gun can be hooked up to force the fuel out of one tank and into the other more quickly.
It's important to note that some Freightliner Cascadia trucks may have a different setup, with a fuel pickup on only one tank or a fuel pickup on both tanks that do not equalize. In these cases, it may be necessary to manually transfer fuel between the tanks or to use a crossover valve to control the fuel flow between them.
To check if fuel is being transferred properly between the tanks, it is recommended to use four buckets—two with fuel and two empty. Place the delivery hoses from the tanks into the buckets with fuel, and the return buckets into the empty buckets. This will help determine if fuel is being pulled and returned equally to each bucket, indicating proper fuel transfer between the tanks.

Troubleshooting: Issues like overflowing tanks may be due to a crossover valve problem
Troubleshooting a Freightliner Cascadia with overflowing fuel tanks can be challenging, especially when the issue involves the fuel crossover system. This problem, as reported by some owners of the 2022 Freightliner Cascadia, is characterised by one fuel tank overflowing to the other side, resulting in a soaked chassis. While the exact cause may be difficult to pinpoint, one potential culprit could be a faulty crossover valve or a related component.
The crossover valve plays a crucial role in maintaining equal fuel levels between the two tanks of the Freightliner Cascadia. When functioning properly, the valve allows fuel to flow between the tanks, ensuring a balanced distribution. However, if the valve becomes stuck or malfunctions, it can lead to an imbalance in fuel levels, resulting in one tank overflowing while the other remains empty.
To diagnose a potential crossover valve issue, it is recommended to check the fuel deliveries and returns to each tank. This can be done using four buckets, with two buckets containing fuel and the other two remaining empty. By connecting the delivery hoses from the tanks to the buckets with fuel and the return hoses to the empty buckets, you can observe whether fuel is being pulled and returned equally. If there is an imbalance, it could indicate a problem with the crossover valve or a related component, such as the fuel line or return line.
In addition to checking the fuel delivery and return system, it is also important to inspect other aspects of the fuel system. This includes ensuring that the tank vent tube is clear, the fuel line coming from the tank is intact, and the correct style of cap is being used. Verifying that the return line to the empty tank is functioning properly is also crucial. These checks can help rule out other potential causes and narrow down the issue to the crossover valve or related components.
While troubleshooting, it is worth noting that some older Freightliner Cascadia models had a lever to control the crossover valve. If your truck has this feature, ensure that it is in the correct position. Additionally, even without a manual valve, the tanks are designed to equalize over time, especially when the engine is off and the truck is parked. If the issue persists despite your troubleshooting efforts, it may be necessary to consult a specialised mechanic who can perform further diagnostics and provide professional repair services.
