Replacing a fuel water separator is a simple task that can be done at home. It involves draining the fuel from the cup and placing the assembly in the freezer for 30 minutes to cause the cup to shrink, making it easier to remove by hand. The filter should then be changed quickly before the cup expands again. The process also involves double clamping the hoses to the fuel filter's ports, attaching the hose from the tank to the in port, and from the engine to the out port. It is important to ensure that the hoses are not pinched.

What You'll Learn
Draining the fuel from the cup
It is worth noting that attempting to remove the cup with pliers before freezing it can be costly, as the plastic cup can be easily damaged. In one instance, a user reported that they had to pay $88.00 to replace the cup after attempting to remove it without freezing. Therefore, it is recommended to always freeze the assembly before attempting to remove the cup.
Additionally, it is important to ensure that the fuel tank outlet hose is higher than the tank itself. This is because fuel cannot flow uphill, and without a fuel pump in the tank, the fuel will not be able to drain properly.
After draining the fuel and replacing the filter, it is important to double-clamp the hoses to the fuel filter's ports, being careful not to pinch the hoses. For outboard and inboard engines, attach the hose from the tank to the "in" port and from the engine to the "out" port. Again, be careful not to pinch the rubber hoses as you double-clamp them.
Finally, start the engine and check for leaks at a fast idle. It is recommended to sea-trial the system close to home at high rpm, keeping a close watch for any leaks.

Putting the assembly in the freezer
- Drain the fuel from the cup by pouring it out through the hose connections.
- Place the entire assembly, including the cup, in your freezer for approximately 30 minutes.
- Monitor the cup during this time; you'll notice it shrinking, which is the desired effect.
- Once the time has elapsed, remove the assembly from the freezer. The cup should now be removable by hand, so proceed with caution.
- Work quickly, as the cup will start to expand again if it warms up.
- Change out the filter, being careful not to cross-thread.
- After replacing the filter, bolt the assembly back onto the engine and reconnect the hoses.
- Prime the system, and you're done!
This method is a workaround for a poorly designed system. Attempting to remove the cup without freezing it first can lead to damage and costly repairs. By following these steps, you can successfully replace the fuel water separator and avoid unnecessary expenses.

Changing the filter
To change the filter, first drain the fuel from the cup by pouring it out through where your hoses connect. Then, put the whole assembly in the freezer for 30 minutes. This causes the cup to shrink and you should be able to take it off by hand. Quickly change out the filter as the cup will expand again if it starts to warm up. Be careful not to cross-thread. Bolt the assembly back on the engine and reconnect the hoses.
If you don't want to use the freezer method, you can use a truck filter wrench to remove the filter.
Double clamp the hoses to the fuel filter’s ports, but don’t accidentally pinch the hoses. Attach the hose from the tank to the “in” port and from the engine to the “out” port. Double-clamp firmly but don’t pinch the rubber hoses. If extra hose is needed, use U. S. Coast Guard-approved Type A1-15 of the same diameter as the hose it’s replacing.
Before you start, get a spent windshield washer fluid container, cut the upper third off, or the like, place it underneath. Unthread it like an oil filter on a car. Get some rags to clean up. Prefill the new filter to near the top with fresh fuel. Wipe the gasket contact surface with some Yamalube 2-stroke oil. Snug up the new filter hand tight – do not overtighten, as you will pay for it next time trying to get it off.

Double clamping the hoses
When double clamping the hoses, it is essential to be cautious and avoid overtightening the clamps. Overtightening can lead to difficulties in removing the clamps during future maintenance or repairs. A snug fit can be achieved by hand-tightening the clamps with a two-hand grip. This ensures that the clamps are secure without applying excessive force.
The double clamping process helps create a secure connection between the hoses and the fuel filter. By firmly clamping the hoses without pinching them, you prevent leaks and ensure the proper flow of fuel. It is a critical step to ensure the safe and efficient operation of the fuel system.
Additionally, it is important to select the appropriate hose type and diameter when performing the double clamping process. Using a hose with the same diameter as the one being replaced maintains a consistent flow rate and prevents any restrictions in the fuel line. It is also recommended to use U.S. Coast Guard-approved hoses to ensure they meet the necessary safety standards.
Overall, double clamping the hoses is a crucial step when replacing a fuel water separator. By following the proper techniques, such as avoiding pinching the hoses and achieving a snug fit, you can ensure a secure and leak-free connection.

Checking for leaks
When replacing a fuel water separator, it is important to check for leaks. To do this, first, drain the fuel from the cup by pouring it out through where your hoses connect. Then, put the whole assembly in the freezer for 30 minutes. This causes the cup to shrink and you should be able to take it off by hand. Change out the filter quickly as the cup will expand again if it starts to warm up.
After changing the filter, bolt the assembly back on the engine and reconnect the hoses. Prime the system and start the engine. Now, check for leaks at a fast idle. If there are no leaks, sea-trial the system close to home at high rpm, watching closely for leaks all the while.
If you notice any leaks, turn off the engine immediately and check the connections. Make sure that the hoses are double-clamped to the fuel filter’s ports and that they are not pinched. If the hoses are not properly clamped, this could be the cause of the leak.
If the hoses appear to be properly clamped and there are still leaks, try using a truck filter wrench to remove the fuel/water separator. This may help to identify any issues with the connections or the separator itself.
