What You'll Learn

Drop the tank and pump out the gas
Dropping the tank and pumping out the gas is a common method to completely drain a fuel tank. This method is often performed by dealerships and repair shops. However, it is important to note that this process can be challenging and may require specialized tools and knowledge.
To begin the process of dropping the tank and pumping out the gas in your 1992 F350, you will first need to gain access to the tank. This may involve jacking up the vehicle, placing it on stands, or using a lift to gain access to the undercarriage. Once you have safely secured the vehicle and can access the fuel tank, you will need to disconnect any fuel lines, hoses, or electrical connections attached to the tank. It is crucial to perform these steps with extreme caution, as gasoline and diesel fuel can be hazardous.
After disconnecting the necessary components, you will need to remove the fuel tank. This step may require the use of a transmission jack or a similar tool to lower the tank carefully. Ensure you have a suitable container to catch the drained fuel. Once the tank is removed, you can begin pumping out the gas. Use a pump designed for fuel transfer and ensure it is compatible with diesel fuel.
It is important to note that the fuel pump does not draw fuel from the very bottom of the tank, so you may need to tilt or turn the tank to ensure complete drainage. Additionally, you may need to use a sump or wet-vac to remove the last bit of fuel from the tank. After draining the tank, it is recommended to flush the tank with fresh diesel fuel and drain it again to ensure no residual gasoline remains. Finally, reinstall the fuel tank and connect all the previously disconnected components, being cautious to avoid any leaks.
Performing this procedure requires a good understanding of automotive systems and safety protocols. If you are uncomfortable with any aspect of the process, it is advisable to seek the assistance of a qualified mechanic or automotive technician.

Siphon through the fuel pump-to-fuel tube connection
To siphon through the fuel pump-to-fuel tube connection, you will need to follow a careful procedure to avoid any health and safety issues. Firstly, it is important to note that gasoline contains poisonous chemical compounds called hydrocarbons, which can cause serious health issues if swallowed or inhaled. Therefore, it is crucial to take precautions to avoid swallowing or inhaling any gasoline fumes during the siphoning process.
Now, to begin siphoning, locate the fuel pump-to-fuel tube connection. You may need to refer to your vehicle's manual or seek advice from a mechanic to identify this connection accurately. Once located, you will need to disconnect the fuel line at this connection point. Ensure you have a container ready to collect the diesel fuel. Place this container at a lower level than the fuel tank to utilize gravity during the siphoning process.
Next, you can use a siphon pump to extract the diesel fuel. There are various types of siphon pumps available, such as hand-operated or mechanical pumps. Hand-operated pumps typically require manual action, such as pushing a plunger or squeezing a bulb, while mechanical pumps may be as simple as flipping a switch. Refer to the instructions provided with your chosen siphon pump for specific operating guidelines.
During the siphoning process, monitor the flow of diesel fuel. Once the fuel begins to flow freely, you may not need to continue operating the pump, as gravity will take over. To stop the flow of fuel, simply raise the end of the tubing or the container to a level higher than the fuel in the tank. This action will cause the flow to reverse, allowing any residual fuel in the pump to drain back into the tank.
Finally, remember to clean your siphon pump after use. Consult the instructions provided with your pump, but generally, pumping a mixture of soap and water through the device and allowing it to air dry is sufficient. By following these steps, you can effectively siphon diesel fuel through the fuel pump-to-fuel tube connection of your 1992 F350.

Drain water from the diesel fuel conditioner module
To drain water from the diesel fuel conditioner module of your 1992 F350, follow these steps:
First, switch off the engine and access the underside of your vehicle. The diesel fuel conditioner module is located on the left-hand frame rail. To drain the module, turn the drain plug counterclockwise until it stops. It is important that you do not use any tools to loosen the drain plug. Once the plug is removed, the water will begin to drain from the module.
It is important to drain the water from the module whenever the warning light illuminates or a message appears advising you to drain the water separator. This occurs when approximately 6.76 fluid ounces (200 milliliters) of water accumulates in the module. If you allow the water level to exceed this amount, it may pass through to the engine and cause damage to the fuel injection equipment.
By following these steps, you can effectively drain water from the diesel fuel conditioner module of your 1992 F350 and prevent potential damage to your engine.

Disconnect the fuel pump driver module
Disconnecting the fuel pump driver module on a 1992 F350 is a complex task and should only be attempted by those with the necessary knowledge and experience. It is important to ensure that you have the correct tools and safety equipment before attempting any work on your vehicle.
Firstly, locate the fuel pump driver module. This can usually be found near the fuel tank, often mounted on the driver's side. Once you have located the module, you will need to disconnect the electrical connector. This is usually held in place with a clip or clamp, so you will need to carefully release this before unplugging the connector. Be sure to set this aside safely so that it does not cause a short circuit or any other damage.
Next, you will need to remove the fuel lines that are connected to the module. These lines supply fuel to the engine, so it is important to place a container or rag underneath the connections to catch any fuel that may spill. Carefully loosen the fittings that hold the lines in place, using the correct size wrench or socket. Once the fittings are loose, you can remove the lines from the module.
At this point, you should be able to remove the module itself. It may be held in place with bolts or other fasteners, so be sure to remove these carefully without stripping the threads. With the module removed, you can now access the fuel tank for draining or other maintenance.
It is important to note that working with fuel can be dangerous, and proper safety precautions should always be taken. This includes wearing protective gear, such as gloves and eye protection, and ensuring that the area is well-ventilated to avoid inhaling fumes. Additionally, be extremely cautious to avoid any open flames or other ignition sources when working with fuel.

Use a separate small fuel pump and some hose
To drain a diesel fuel tank from a 1992 F350, one method that can be used is to purchase a separate small fuel pump and some hose. This can be done for as little as $30, and is likely the easiest way to drain the tank.
Firstly, purchase a 12-volt fuel pump and 10 feet of fuel-rated hose from a parts store. You will also need alligator clamps to hook onto your battery. You can then begin to drain the tank.
The first step is to undo the clip and unhook the line on the fuel filter that is closest to the firewall. This is the in-tank line. Take the heater hose and slide it over the copper fitting, then insert this copper fitting into the line you just disconnected. Ensure that the other end of the hose is in a container for the fuel to drain into.
The next step is to hook the alligator clamps onto your battery. It does not matter which way you attach the clamps. The pump should then start running. If the pump is not working, switch the leads on the battery and it should start. Continue draining the tank until it is empty. Remember to disconnect the battery leads when switching containers.
Note that if your diesel fuel has been contaminated with gasoline, you will need to replace the fuel/water separator filter under the truck by the tank, as well as the fuel filter under the hood.
