The Racor Turbine fuel filters are the marine industry standard, and while they may need attention, they are easy to rebuild. The process of tightening a Raycore fuel filter involves several steps. Firstly, it is important to relieve any internal pressure by opening the drain plug. Then, a socket wrench can be used to twist the canister free and collect excess fuel. The next step is to remove the T handle on the top of the assembly, pull up on the plastic handles, and discard the old filter. It is crucial to replace the O rings on both the T handle and the lid, and then insert the new filter. Finally, the T handle can be tightened by hand, and a quarter turn with a wrench completes the process.

Drain the filter
Draining the filter is a crucial step in maintaining your Raycore fuel filter. Here is a detailed guide on how to effectively drain the filter:
Locate the Drain Plug
The first step in draining the Raycore fuel filter is to locate the drain plug, which is typically at the bottom of the filter bowl. This drain plug, also known as the pet cock assembly, is responsible for releasing the fuel from the filter.
Relieve Internal Pressure
Before attempting to open the drain plug, it is essential to relieve any internal pressure within the filter. This can be done by using a socket wrench to slightly loosen the canister, allowing built-up pressure to escape. Be cautious and use the appropriate tools to avoid any fuel spray or spillage during this step.
Open the Drain Plug
Once the internal pressure is relieved, you can proceed to open the drain plug. Use a wrench to turn the nut closest to the hose barb, which controls the opening and closing of the pet cock assembly. Turn it in the left direction, following the standard "lefty loosey" rule. Make sure to have a container ready to collect the drained fuel.
Clean and Replace
After successfully draining the fuel, it is good practice to clean the drain plug assembly. Remove the assembly from the bowl and clean or replace the gasket and O-ring, ensuring they are in good condition. This maintenance step helps maintain the proper functioning of the fuel filter and prevents leaks.
Refill and Reinstall
Before reinstalling the filter, ensure that you refill it with clean fuel. It is crucial to use fuel that is free of contaminants, as even a small amount of water can lead to serious engine damage. Refer to the instructions provided with your specific Raycore fuel filter model for the correct procedure to refill and reinstall the filter.
Remember to follow safety precautions when working with fuel, and always ensure that the engine is turned off before performing any maintenance or repairs on the Raycore fuel filter.

Remove the old filter
To remove the old Raycore fuel filter, start by opening the drain plug to relieve any internal pressure. You can use a wrench on the nut closest to the hose barb to open the drain plug. Remember to place a container underneath to catch any excess fuel.
Next, use a strap wrench with a rubber strap to twist the canister free and remove the old filter. Be careful not to slip, especially if the fuel filter is near the shaft cooling hose barb, as you might need to replace a broken hose barb.
Once the canister is removed, you can clean the drain plug and replace the gasket and O-ring with new ones. The O-rings should be lubricated with some fuel.
If your Raycore fuel filter has a pressure gauge, use a wrench on the hex portion of the gauge to remove it. Do not turn it using the gauge head.
Before installing the new filter, make sure to drain a little fuel out of the filter to prevent spills when removing the lid.

Prepare the new filter
Preparing the new filter for your Raycore fuel filter is a simple process. Firstly, ensure you have the right tools for the job. You will need a wrench, a strap wrench with a rubber strap, and a plastic container to collect excess fuel.
Before you begin, shut off the fuel supply to the Raycore filter. Then, open the drain plug to relieve any internal pressure and collect the excess fuel in your plastic container. It is important to note that the drain plug will be the nut closest to the hose barb. Once the pressure is relieved, use your wrench on the hex portion of the gauge, twisting the canister free. Remember not to turn the gauge head itself.
Now you can prepare your new filter. Replace the "O" rings, including the one for the gauge stem and the black gasket "O" ring on the lid. These should come packed with your new filter. Lubricate the new "O" rings with some fuel. Fill the new filter with clean diesel fuel, being careful to avoid any contaminants, as even a drop of water could cause serious engine damage.
Once the new filter is prepared, you are ready to screw it back into place. Hand-tighten the filter first, and then give it a quarter turn with your wrench.

Insert the new filter
To insert the new filter, first, ensure you have the correct replacement filter for your specific Raycore model. The process varies slightly depending on the model.
For the Racor 110A filter, you will need to refill the canister with fuel before reinstalling it. You should also replace the rubber gasket in the filter body with a new one.
For the Racor 500, 900, and 1000 models, the process is relatively simple and similar. You will need to remove the "T" handle on the top of the assembly. Pull up on the two little plastic handles on the side of the old filter and discard it. Replace the "O" rings on both the "T" handle and the lid with new ones, which should come with the new filter. Drop the new filter into place and tighten the "T" handle. Remember to replace the O-ring for the gauge stem as well. Lubricate the new O-rings with some fuel before installing.
Before inserting the new filter, you may need to drain a small amount of fuel from the old filter to prevent spills when opening the lid. After installing the new filter, top up the fuel in the Raycore and open the previously shut valve. Ensure that the bulb is upright during this process.
It is important to note that you should not over-tighten the new filter. Just snug is fine. Additionally, make sure you are turning the filter in the right direction when tightening.

Before installing the new filter, it is important to relieve any internal pressure by opening the drain plug. This will prevent any fuel spillage when removing the old filter. Place a container underneath to catch any excess fuel.
Now, remove the old filter. For the Racor 110A filter, you will need to use a socket wrench to twist the canister free. For other models, such as the Racor 900, you may be able to simply remove the "T" handle on the top of the assembly and pull up on the plastic handles to discard the old filter.
Next, replace the "O" rings. Install the new "O" ring that came with the replacement filter. You may also need to replace the rubber gasket in the filter body where the canister screws in. Lubricate the new "O" rings with some fuel.
Finally, install the new filter. Fill the new filter with clean diesel fuel to the top. Screw it back on according to the instructions on the filter, which usually involves hand-tightening and then giving it a quarter turn with a wrench. Do not over-tighten; just snug is fine.
Your Raycore fuel filter is now tightened and ready to use.
