Racor 500 filters are easy to maintain, clean and use
For a Yanmar 2GM20 engine, the Racor R11T filter element for the 110 Racor filter assembly is recommended. The Yanmar (Primary) fuel filter element is the on-engine filter assy. Yanmar #104500-55710. The Racor 500 filter is also mentioned as a suitable option for this engine.
The Racor 500 filter is indeed easy to maintain and use. It is considered a "wonderful bit of kit" by some users, and the glass bowl design allows you to see if there is any water present. The filter is also easy to change, and the fuel flow is good enough to ensure clean fuel.
In terms of maintenance and cleaning, the Racor Turbine filters are generally easy to rebuild, and the Racor 500 is no exception. Rebuilding the filter typically takes around 25-30 minutes, and the required rebuild kits are available at a reasonable price.
To clean and rebuild the Racor 500, you will need to remove the four machine screws holding the bowl onto the housing. Then, slide the aluminum clamping ring up and off the bowl and remove the bowl from the housing. You can then clean the turbine cover and the turbine itself, and replace the gasket and O-ring with new ones. When reassembling, ensure that the check valve gasket is properly oriented, with the dished side facing away from the ball. Do not over-tighten; just snug is fine.
Additionally, it is important to inspect the gasket for any twists, as this can affect the seal. The gasket is square in cross-section, so twists can cause diesel leaks. When rebuilding, it is recommended to replace the little red O-ring at each filter change. You can use products like Gunk Engine Degreaser, Lemon Joy, and mineral spirits to clean the parts and the filter housing.
Overall, the Racor 500 filter is user-friendly in terms of maintenance, cleaning, and general use, making it a popular choice for many boat owners.

Yanmar 2GM20F secondary fuel filter maintenance
The Yanmar 2GM20F is a diesel engine. The primary fuel filter is the one closest to the fuel tank and is responsible for filtering most particles and water from the fuel. The secondary fuel filter is the smaller one built into the engine. It is recommended to clean the primary filter every 50 hours of use.
The following steps outline the process for changing the secondary fuel filter on the Yanmar 2GM20F:
- Loosen the air bleed plug on top of the fuel filter body. It is the smaller screw towards the rear of the unit.
- Ensure the fuel tank valve is open, then operate the primer lever (lift pump) on the fuel transfer pump.
- Operate the lever while observing the fuel emitted around the M10 bleed plug. Air will be emitted with the fuel.
- Stop operating the lever when the fuel is free of air, then tighten the air bleed plug. Use a rag to clean any spilled fuel from the housing.
- Remove the filter element from the canister. Inspect and discard the element if it is dirty, damaged, or has been three years since it was last changed.
- Clean the canister in clean diesel fuel. Do not wipe the inside of the canister with any type of cloth or tissue paper, as this may introduce particles that could cause problems downstream.
- Install the new filter element in the canister.
- Install the canister on the filter body, then install the retainer ring and tighten it hand-tight.
- Before operating the engine, run the engine for 30 minutes to ensure any air introduced to the fuel supply passes through the system.
- Check all banjo bolt fuel connectors and the filter housing for any signs of leaks.
It is recommended to replace the Racor filter element (for the 110 Racor filter assembly) and the Yanmar primary fuel filter element annually, as part of the winterizing process. The Racor filter element is Racor R11T and can be purchased from Yanmar dealers for around $13.50. The Yanmar primary fuel filter element is Yanmar #104500-55710 and costs around $5.12.

Racor 120at filter is difficult to change out
The Racor 120AT filter is a compact fuel filter and water separator for smaller diesel engines. It is suitable for use in generator sets and small construction equipment. The 120AT filter is highly effective, removing 99% of water and solid contamination. It is also versatile, as it can handle two different fuel sources.
However, some customers have reported difficulties with removing the bowl and plugs. This is a common issue with the Racor 120AT filter, and it can be challenging to access and change out the filter element. The bowl and plugs can become stuck, and in some cases, they may need to be forced open, which can damage the filter housing. This issue is not unique to the 120AT model, as other Racor filters have been known to present similar problems.
One possible solution to this issue is to invest in a new fuel tank. This can help eliminate fuel maintenance problems and ensure clean fuel is entering the system. Another option is to upgrade to a Racor 500 filter, which has a glass bowl that allows for visual inspection of the fuel and is reported to be easier to change.
It is important to consider the specific needs of your engine when selecting a fuel filter. The Racor 120AT filter may still be a suitable option for some applications, despite the challenges associated with changing out the filter element. However, it is always a good idea to consult with a marine specialist or mechanic to determine the best filter for your specific needs.

The primary fuel filter should be changed out to a R12T: 5 micron
Upgrading the fuel filter on a Yanmar 2GM20 engine to a Racor filter is a common choice for boat owners. The Racor 500, for example, has a glass bowl that lets you see if there is any water in the fuel, and its filter is easy to change. The fuel flow is good enough to use a 2-micron filter on a smaller engine. However, a 5-micron filter is also a good choice for a Yanmar 2GM20 engine.
The Racor R12T is a fuel water separator filter that is suitable for outboard motor marine engines. It is available in 4, 5, and 10-micron ratings. The 10-micron element can be used for primary or secondary filtration, depending on the engine and application. The R12T filter features Aquabloc®, which removes nearly 100% of water by repelling moisture and directing it downward into the bowl with larger particles for quick removal through the drain.
The primary fuel filter for a Yanmar 2GM20 engine should be changed out regularly, and a Racor R12T 5-micron filter is a suitable replacement. This filter will effectively remove water and debris from the fuel, ensuring the engine receives clean fuel and reducing the risk of performance issues or damage.
It is important to consider the specific engine and application when selecting a fuel filter. The Yanmar 2GM20 engine may have different fuel flow characteristics than other engines, so it is essential to choose a filter that is compatible and will provide the necessary level of filtration. Additionally, the accessibility of the filter and ease of replacement are also important factors to consider when upgrading to a new fuel filter.
By upgrading to a Racor R12T 5-micron filter, boat owners can benefit from improved fuel filtration, enhanced engine performance, and easier maintenance. This filter is designed to effectively remove water and contaminants, ensuring that the Yanmar 2GM20 engine receives clean fuel and runs smoothly. Regular replacement of the primary fuel filter is crucial to maintain the engine's health and extend its lifespan.
