26-gallon tanks are replaceable with 52-gallon tanks
The 2005 Dodge Ram 1500 is equipped with a 26-gallon fuel tank as standard. While it is possible to replace this tank with a larger 52-gallon tank, it is important to note that not all fuel tanks are interchangeable, even if they are from the same model of truck.
For instance, a user on Reddit reported that they were unable to swap the 26-gallon tank from their 2005 Dodge Ram 1500 with a 26-gallon tank from a 2003 model. They speculated that the tanks for the 2002-2003 models may be different from those of the 2004 and newer models.
However, S&B offers a 52-gallon replacement fuel tank that is compatible with the 2005-2022 Dodge Ram 2500/3500 Crew, Quad, and Mega Cab with a short bed. This larger tank can replace the original 26-gallon tank without requiring any cutting, drilling, or special modifications, making the installation process faster and trouble-free.
It is worth noting that the S&B 52-gallon tank holds 10 more gallons than competitor tanks, allowing you to save time, go further, and get more out of your truck. Additionally, the tank was designed to use the OEM locking ring, ensuring a perfect seal and securely retaining the fuel pump.
Therefore, while it is possible to replace the 26-gallon tank with a 52-gallon tank, it is important to ensure that the replacement tank is compatible with your specific model and year of the Dodge Ram.

The fuel tank capacity is 112 litres
The fuel tank capacity of the 2005 Dodge Ram Diesel is 112 litres. This is equivalent to approximately 30 gallons.
The Dodge Ram Diesel is a powerful vehicle, and its fuel tank capacity reflects this. With a capacity of 112 litres, it offers a generous amount of fuel storage, allowing for longer trips without the need for frequent refuelling. This can be particularly advantageous for those who frequently travel long distances, use their vehicle for work, or enjoy road trips and camping.
The fuel tank capacity of 112 litres provides a good balance between range and efficiency. While larger tanks can offer even greater range, they also add weight to the vehicle, which can impact its fuel efficiency and overall performance. The 112-litre tank strikes a good compromise, ensuring a reasonable range without sacrificing the vehicle's performance and handling characteristics.
It's important to note that the actual range achieved on a full tank will depend on various factors, including driving habits, road conditions, terrain, and the condition of the vehicle. Efficient driving practices, such as maintaining a steady speed, avoiding abrupt acceleration and braking, and ensuring proper tyre inflation, can help maximise the range and make the most of the 112-litre fuel tank.
Additionally, it's worth mentioning that the fuel tank capacity may vary slightly between different variants of the 2005 Dodge Ram Diesel, depending on the specific model, configuration, and market. While the standard capacity is 112 litres, there may be slight variations in certain cases, and it's always a good idea to refer to the vehicle's manual or specifications for the most accurate information regarding its fuel tank capacity and fuel system.
