What You'll Learn
Removing the pickup tube
First, you will need to disconnect the fuel line hose. This will provide access to the pickup tube assembly. Make sure you have a good amount of clearance to work with. Depending on your setup, you might need to remove the valve handle to create more space.
Next, identify the fuel shut-off valve and turn it counter-clockwise to unscrew it from the tank. You may need to use a wrench to hold the square block still while turning the valve. Be cautious when applying force, especially if the fittings are corroded, as you don't want to break anything.
Once the valve is removed, you should have access to the hose clamps. Remove the fuel hose from the valve. There may be two hose clamps, depending on your setup. It is important to have a plug handy to seal off the hose and prevent any fuel discharge.
Now, you can focus on the pickup tube itself. The fitting will be tight, so you will need to apply a good amount of force to loosen it. Use a properly sized wrench to hold the large nut that sits flush to the tank's top surface. This will prevent it from moving while you work on loosening the pickup tube fitting. You may need to apply some lubrication to the threads to help loosen it further.
Finally, once the fitting is loose, continue to work on it until it comes out completely. The tube should then pull out of the tank. Be cautious when handling the tube, as it may have sharp edges or debris on it.
It is always recommended to have a professional mechanic perform such tasks if you are unsure about any part of the process. They will have the necessary tools and experience to ensure the job is done safely and correctly.

Removing the fuel hose
Before beginning, it is important to ensure that the tank is empty and that any remaining fuel is drained or blown out of the hose to minimize spills. This can be done by unhooking the hose from the Racor and opening the valve with the hose end elevated.
The next step is to locate the hose clamps that secure the fuel hose in place. Depending on the specific setup of your fuel system, there may be one or two hose clamps. If there are two clamps, both will need to be removed to detach the hose completely. Turn the valve counter-clockwise to access the hose clamps more easily. If there is insufficient clearance to turn the assembly while connected to the hose, try accessing it from the cockpit side.
Once the hose clamps are accessible, use the appropriate tool to loosen and remove them. This may require a specialized tool, depending on the type of hose clamps used. With the hose clamps removed, the fuel hose should be free to detach from the valve. Gently pull on the hose to remove it from the valve. If the hose is stubborn or stuck, do not force it, as this could damage the hose or the valve. Instead, try wiggling the hose gently or using a gentle tapping motion with a soft mallet to loosen it.
In some cases, the fuel hose may be connected to a fuel pickup tube or a fuel screen. If this is the case, it is important to take extra care when removing the hose to avoid damaging these components. Gently twist and wiggle the hose to loosen it from the surrounding parts. If the fuel screen is stuck to the hose, it may need to be carefully removed or detached before proceeding.
After the fuel hose has been successfully removed, it is important to plug or cap the open ends to prevent fuel discharge and spills. Use appropriate fittings or caps to securely seal the hose ends. Additionally, have a plug or a seal ready to close off the valve opening to prevent fuel leakage.
By following these steps, you can safely and effectively remove the fuel hose from your semi fuel tank, allowing you to access and service the fuel screen or other components as needed. Remember to work carefully and patiently, especially when dealing with stubborn hoses or fittings, to avoid any damage to your fuel system.
