What You'll Learn
The front tank is 16 gallons
The front fuel tank of a 1985 F250 has a capacity of 16 gallons. This is a standard size for the front tank of Ford F-series trucks from 1985 to 1986.
The rear tank of the 1985 F250 has a capacity of 19 gallons. This is a standard size for the rear tank of Ford F-series trucks from 1985 to 1986.
It is important to note that the fuel tank capacities can vary depending on the model and year of the F250. Some models may have larger or smaller tanks, and it is possible that previous owners have modified the tanks.
The fuel tank capacity of a vehicle is an important consideration for several reasons. Firstly, it determines the vehicle's range or how far it can travel on a full tank of fuel. This is influenced by the tank size and the vehicle's fuel efficiency. Secondly, the fuel tank capacity can impact the weight of the vehicle, which in turn can affect its performance and handling. Finally, the fuel tank size can also influence the frequency of refuelling, with larger tanks requiring less frequent refuelling than smaller tanks.
For owners of a 1985 F250, understanding the fuel tank capacity and the vehicle's fuel efficiency can help in planning trips and refuelling stops. It is also important to be aware of any potential modifications made to the fuel tank by previous owners, as this may impact the vehicle's performance and fuel efficiency. Regular maintenance and replacement of worn-out fuel system parts can help optimize the vehicle's performance and fuel efficiency.

The rear tank is 19 gallons
The rear fuel tank of a 1985 F250 is 19 gallons. This is a standard size for Ford F-series trucks from 1980 to 1986. The rear tank is typically larger than the front tank, which is often reported to be between 14 and 16 gallons.
The rear tank's capacity can be affected by the presence of a spare tire, as some models have the spare tire located above the rear tank. In such cases, installing an oversized tank may not be feasible without modifying the placement of the spare tire.
It's worth noting that fuel tank capacity can also vary depending on the previous owner's modifications. For example, one owner reported that their 1985 F250 had a rear tank that could hold only 15.363 gallons, while another owner stated that their rear tank had a capacity of 19 gallons.
To ensure the accuracy of fuel levels, it is crucial to have a properly functioning fuel gauge sending unit. This unit is mounted inside the fuel tank, and a faulty one can lead to incorrect fuel level readings on the dashboard gauge.
When considering replacement fuel tanks or upgrading to larger capacities, it is essential to take into account the vehicle's make, model, and year, as well as any modifications made by previous owners.

The rear tank can be replaced with a 42-gallon tank
The 1985 F250 has a rear fuel tank capacity of 19 gallons. However, it is possible to replace the stock rear tank with a larger, aftermarket one.
Some owners have opted for a 38-gallon rear tank, which requires the deletion of the midship tank. This modification eliminates the need for hot fuel return and carburation, resulting in a simpler fuel system. The 38-gallon tank provides significantly increased fuel capacity, allowing for longer distances between refuelling stops.
Another option is to upgrade to a 42-gallon rear tank, as one owner has done for their 1986 F250. This oversized tank requires modifications to the pickup tube and sending unit arm to ensure accurate fuel level readings. The spare tire also cannot be stored in its standard location due to the larger tank size.
For those seeking a balance between increased fuel capacity and ease of installation, a 33-gallon rear tank is an option worth considering. This size may offer a better balance, as it provides a notable increase in fuel capacity while potentially requiring fewer modifications and retaining the stock appearance.
It is important to carefully plan and research any fuel tank modifications to ensure compatibility, safety, and compliance with local regulations.

The front tank can be replaced with a 38-gallon tank
The 1985 F250 is a Ford Truck with a dual gas tank setup. The front tank has been quoted as being 15.5, 16, or 19 gallons in size, while the rear tank is usually 19 gallons. However, Ford offered a larger, optional tank for the rear, which increased the capacity to 38 gallons.
The 38-gallon tank is available from several suppliers, and prices vary. Some owners have opted for a 33-gallon tank, which is a more common size for the front tank of the F250. This size is more easily sourced and is a more straightforward replacement.
The 38-gallon tank is an option for those seeking greater fuel capacity and range. It is a more complex installation, and the larger size will impact the overall appearance of the truck, but it is a viable modification for the F250.

The fuel tank sending unit is mounted in the fuel tank
The 1985 Ford F-250 is a pickup truck with a variety of fuel tank options. The stock tank has a capacity of 17 gallons, but some models have larger tanks of up to 38 gallons.
The fuel tank sending unit is an important component of the fuel system, providing information about the amount of fuel in the tank to the gauge inside the vehicle. This sending unit is mounted inside the fuel tank of the 1985 F-250.
There are several types of sending units available for the F-250, depending on the size of the fuel tank and whether it is mounted on the side or rear of the vehicle. For example, a 1985 F-250 with a 16.5-gallon mid-frame-mounted tank requires a specific sending unit, while a different unit is needed for a 19-gallon tank.
The sending unit can be purchased separately or as part of an assembly, and it is important to ensure that the correct unit is ordered to match the vehicle's fuel tank size and type. The sending unit typically includes a float, which may be made of brass or plastic, and an O-ring.
Some owners of the 1985 F-250 have opted for larger, aftermarket fuel tanks, which may require adjustments to the sending unit arm and pickup tube to ensure accurate fuel level readings.
