Water in your fuel tank can cause damage to your engine, so it's important to drain it. The process for draining water from the fuel tank of a Ford 250 diesel truck varies depending on the model year. For a 2001 Ford F-250 4.2-litre Diesel model, there is a yellow lever on the fuel filter housing in the rear to drain the water. For a 6.7L Diesel model, you need to access the underside of your vehicle, locate the diesel fuel conditioner module, and drain it by turning the drain plug counterclockwise.
Characteristics and Values Table for Draining Water from Fuel on a Ford 250 Diesel
| Characteristics | Values |
|---|---|
| Fuel Bowl Drain Method | Turn the yellow lever on the fuel bowl to drain the fuel bowl. Place a bucket underneath the engine to catch the fuel. |
| Fuel Filter Water Trap Method | Switch off the engine and access the underside of the vehicle. Locate the diesel fuel conditioner module on the left-hand frame rail. Turn the drain plug counterclockwise to drain the filter into an appropriate container. Do not reuse the drained fuel. Tighten the drain plug by turning it clockwise until strong resistance is felt. |
| Siphoning or Pumping Method | Lift the bed or lower the tank to access the top of the tank where the fuel pump module is located. Siphon or pump out the fuel. Alternatively, disconnect the fill nozzle under the bed to siphon the fuel. |

Draining the fuel bowl
Locate the Fuel Bowl and Prepare for Draining
Begin by locating the fuel bowl on your Ford F-250 Diesel engine. The fuel bowl is typically found near the top of the engine, and it is usually covered by a yellow lever or handle. Place a bucket or an appropriate container underneath the engine to catch the drained fuel. It is important to ensure that the engine is switched off before proceeding.
Drain the Fuel Bowl
Once you have located the fuel bowl, it's time to start draining it. If your fuel bowl has a yellow lever, simply turn it, and the fuel will begin to drain from the bowl. You will hear a gurgling sound coming from the bowl as the fuel drains out. Alternatively, if your fuel bowl has a drain valve or plug, turn it counterclockwise until it opens. Do not use any tools to loosen the drain plug, and be sure to drain the fuel into an appropriate container.
Managing the Draining Process
During the draining process, it is important to manage the flow of fuel and water. Water will typically settle at the bottom of the fuel bowl, so it will drain out first. Hold the drain open for about three to four seconds and then close it off. This will help ensure that you only drain the water and not all of the fuel from the bowl.
Refill and Prime the System
After draining the water from the fuel bowl, it is important to refill the bowl with fresh fuel. Turn the key to the "on" position (but do not start the engine) and let the fuel pump refill the bowl. Wait for about 20 seconds, and then cycle the key to the off position. Repeat this process of turning the key to "on" and "off" positions a few times to effectively flush and prime the system.
Final Steps
Once you have completed the draining, refilling, and priming process, you can start the engine. Ensure that you dispose of the drained fuel responsibly and do not reuse it. Additionally, refer to your owner's manual for any specific instructions or precautions related to your Ford F-250 Diesel model.

Using a siphon hose
First, locate the fuel filter housing. It is usually found on the underside of your vehicle, with the diesel fuel conditioner module on the left-hand frame rail. Make sure to switch off the engine before accessing this area.
Next, look for the yellow lever or handle on the fuel filter housing. This lever is used to drain the water from the fuel bowl. Place a bucket under the engine to catch the fuel and water. If you have a vacuum hose, you can slip it on to the steel tubing near the cross member to direct the flow into the bucket.
Once you are ready, turn the yellow lever counterclockwise to open the drain valve. You will hear a gurgling sound as the water and fuel start to drain from the fuel bowl. Hold the lever open for about three to four seconds to allow the water to drain out first, as it settles at the bottom of the bowl. Then, close the valve by turning the lever clockwise until it stops and you feel strong resistance. Do not use any tools to loosen or tighten the drain plug.
After draining the water, prime the system by turning the key to the "on" position for 30 seconds, then to the "off" position. Repeat this step once more. Finally, turn the key to the "on" position again and let the fuel pump refill the bowl. Wait for about 20 seconds before starting your truck.
By following these steps, you can effectively use a siphon hose to drain water from the fuel tank of your Ford 250 Diesel, helping to prevent potential damage to your engine and fuel injection equipment.

Draining the diesel fuel conditioner module
Firstly, ensure the engine is switched off. This is imperative for safety and practical reasons, as water passing through to the engine can cause fuel injection equipment damage. Next, access the underside of your vehicle. The diesel fuel conditioner module is located on the left-hand frame rail. Once located, turn the drain plug counterclockwise without using any tools until it stops.
As the diesel fuel begins to drain, collect it in an appropriate container, aiming to collect approximately 0.5 gallons or 2 litres. It is important to note that the drained fuel should not be reused. After draining, tighten the drain plug by turning it clockwise until it stops and strong resistance is felt. Again, do not use any tools to tighten the drain plug.
Finally, prime the system by turning the key to the 'on' position for 30 seconds, followed by turning it to the 'off' position. Repeat this process of turning the key to 'on' and 'off' for another 30 seconds, twice more. Following these steps will help ensure that the diesel fuel conditioner module is effectively drained and the vehicle is ready for safe operation.

Flushing the fuel bowl
To ensure you only drain the water from the bowl, and not all of the fuel, hold the lever open for three to four seconds, then close it off. The water will be at the bottom of the bowl and will drain out first. You will hear a gurgling sound coming from the bowl as it drains.
After draining the water, turn the key to the "on" position, but do not start the truck. Let the fuel pump refill the bowl. Wait around 20 seconds, then cycle the key to the off position, then to the "on" position again. Wait another 20 seconds, then start the truck.
You can also extend the drain line to make the process easier. One method is to feed a rubber extension line back up through a second hole in the spring perch. This prevents the line from dangling. Another method is to attach a hose to the drain tube and place the other end of the hose in a bucket.
If your fuel bowl is plugged, you can use a long piece of wire to unplug it.

Dropping the tank
Firstly, locate the fuel tank and prepare the necessary tools and safety equipment. Ensure you are wearing appropriate protective gear, such as gloves and eye protection, and have a suitable container to catch the drained fuel. Place a drain pan or container under the vehicle, large enough to catch any spilled fuel during the process.
Next, disconnect the fuel lines and any other components connected to the fuel tank. This may include electrical connections and hoses. Be sure to label or mark these connections to ensure proper reassembly. Once all connections are disconnected, carefully lower or remove the fuel tank from the vehicle, depending on its mounting configuration.
With the tank lowered or removed, you can now drain the remaining fuel and water. Use a siphon or pump to remove the contents, being careful not to spill any fuel. Completely drain the tank and, if necessary, flush it with fresh diesel fuel to ensure no water or contaminants remain. You may also choose to change the fuel filters at this stage to prevent any water or contaminants from entering the fuel system.
Finally, reinstall the fuel tank and reconnect all the previously disconnected components. Ensure all connections are secure and properly tightened. Refill the fuel tank with fresh diesel fuel and start the engine. It may be necessary to cycle the key on and off a few times to prime the fuel system and ensure proper fuel flow.
