Installing a fuel tank screen above the sediment bowl can be a simple task, but it is important to do it correctly to ensure the screen fits snugly and effectively filters out any sediment or contaminants in the fuel. The first step is to remove the filter bowl and completely drain the fuel tank. After ensuring the tank is dry, a fuel screen can be installed in the outlet. The screen should be tall enough so that any sediment or water settles at the bottom, and only clean fuel passes through. It is important to choose the right size and type of screen, and in some cases, it may be necessary to modify the screen or the inlet to ensure a tight fit.

What You'll Learn
Removing the filter bowl and draining the tank
To remove the filter bowl and drain the tank, start by running the car as close to empty as possible. This will reduce the amount of fuel that needs to be drained. If you have put the wrong fuel type in your car, it is important to drain the tank, flush the fuel lines, and replace the fuel filters. Old fuel can also cause poor running, so consider draining and replacing the fuel if your car has been sitting for more than six months to a year.
Next, locate the diesel fuel conditioner module and place an appropriate container under the drain port. Rotate the drain counterclockwise until the O-ring is visible, and allow the module to drain for approximately 25 seconds or until clean fuel is observed. If no liquid drains, the drain may be clogged.
If you are experiencing issues with the fuel filter drain not stopping, it could be due to a vacuum or a valve inside the fuel filter/fuel pump housing that is stuck open. To address this, remove the filter housing and break the O-ring seal to stop the siphoning.
Additionally, with fuel tank levels above 3/4 tank, it may be necessary to loosen the bowl by a few turns before opening the drain to prevent fuel from siphoning out of the tank.
After draining the tank, it is important to flush the tank with fresh fuel to ensure that any remaining residue or contaminants are removed.

Using a shim to secure the screen
Installing a fuel tank screen above the sediment bowl can be done by following these steps:
Firstly, remove the filter bowl and let the tank drain completely. It is recommended to add a small amount of gas to rinse out any remaining residue. Use a suitable tool to dislodge and break up any chunks of residue, ensuring that you remove as much as possible.
The next step is to install the fuel screen in the outlet. The screen should be tall enough so that any sediment or water settles at the bottom, allowing only clean fuel to pass through. This will cause the tank to act as a filter bowl, so it is important to occasionally remove and drain any build-up at the bottom of the tank.
In some cases, you may find that the tolerance between the opening on the sediment bowl nipple and the stem of the screen is too loose, which could cause the screen to become dislodged. To address this issue, you can use a shim to secure the screen in place.
One approach is to cut a thin piece of aluminum, such as from a soda can, into a narrow strip less than 1/2 inch wide. Wrap this strip tightly around the stem of the screen assembly, creating a snug fit within the sediment bowl nipple. This shim stock technique ensures that the screen remains securely seated inside the fuel tank.
By screwing the sediment bowl with the filter screen assembly tightly secured using the shim, you can achieve a stable and functional installation. This method has proven successful in tractor restoration projects, ensuring a secure fit for the fuel tank screen above the sediment bowl.

Screens come in various sizes
When choosing a screen size, consider the following:
- The diameter of the fuel inlet: The screen should fit snugly inside the fuel inlet to prevent any debris or contaminants from bypassing the screen and entering the fuel system.
- The depth of the sediment bowl: The screen should be tall enough to sit securely inside the sediment bowl, allowing for adequate fuel flow while capturing any sediment or water that may settle at the bottom.
- The shape of the sediment bowl: Some screens are dished or curved to fit the contours of the sediment bowl, maximizing the screen area and improving filtration.
- The thread size of the sediment bowl inlet: The screen should have a tapered stem that matches the thread size of the sediment bowl inlet for a secure and tight fit.
It's recommended to measure the dimensions of your fuel tank and sediment bowl inlets to ensure you select the appropriately sized screen. Additionally, some screens may require minor adjustments or shimming to achieve a snug fit, as mentioned in the installation instructions.
By choosing the right screen size and ensuring a proper fit, you can effectively prevent contaminants from entering your fuel system and maintain the optimal performance of your engine.

The screen should fit tightly
To achieve a tight fit, the screen must be correctly sized and securely installed. The screen should be tall enough to extend into the fuel tank, allowing it to effectively capture and trap sediment before it reaches the engine. A proper fit also ensures that the screen does not obstruct fuel flow or create restrictions that could impact engine performance.
If the screen is too loose, it may require shimming or soldering to achieve a tighter fit. Shimming involves using thin materials, such as aluminium from a soda can, to create a snug fit between the screen and the sediment bowl. This technique ensures that the screen remains securely seated and can be pressed into place by hand.
Soldering, on the other hand, involves adding a small amount of solder to the stem of the screen and then filing it to achieve a custom fit. This method provides a more permanent solution for a loose-fitting screen. It is important to note that soldering may not be necessary for all screens, as some are designed with tapered stems that naturally fit tightly in most filter bowl inlets.
Additionally, it is worth mentioning that the screens come in various sizes, so selecting the appropriate size for your specific application is crucial. A screen that is too small may not effectively filter the fuel, while a screen that is too large may require additional modifications for a secure fit.

The screen will be inside the sediment bowl
Installing a fuel tank screen above the sediment bowl requires some careful work, but it can be done. The screen will be inside the sediment bowl, catching any sediment that doesn't settle at the bottom of the bowl, and preventing it from entering the carburetor.
First, remove the filter bowl and let the tank drain completely. Add a small amount of gas to rinse out any sediment or debris. You can use a tool to break up any chunks and remove as much debris as possible. The screen will be installed in the outlet, ensuring that only clean fuel passes through.
The screen should be tall enough so that sediment and water settle at the bottom, and don't pass through the screen. This will need to be drained occasionally. The screen enters the tank through the hole that the sediment bowl threads into and should press-fit into the sediment bowl.
The tolerance between the opening on the sediment bowl nipple and the stem of the screen should be considered. If it is a loose fit, you can use a shim to secure it tightly. One user reported using a strip of aluminium from a Pepsi can to create a shim, wrapping it around the stem of the screen assembly to create a tight fit.
You can also use tubing to raise the intake point, which will help to avoid picking up sediment from the bottom of the tank. This can be made from copper pipe, rubber hose, or plastic tubing.
