When To Change Your Water Fuel Separator?

The frequency with which you should change a water fuel separator depends on a variety of factors, including the type of vehicle, the age of the vehicle, the climate and environment in which the vehicle is used and stored, and individual preference. For example, some boat owners change their water fuel filters once a year or every 100 engine hours, while others change theirs every six months, or even twice a year. Similarly, some truck drivers change their water fuel separators every 10,000 miles, while others change theirs every 12,000 to 15,000 miles.

Fuel water separator filters should be changed annually or after 100 engine hours

It is also recommended to inspect the filters every six months and carry spares and a filter wrench when fishing in the gulf. Priming new filters with fresh fuel before installation is also a good idea, as is marking the canister with the date and engine hours. Finally, spraying the filter housing and canister with Corrosion X Red helps prevent corrosion.

Some people may suggest changing the filters twice a year or every six months, while others may suggest changing them more frequently, such as every 50 hours or every 200 hours. It is also recommended to change the oil filter every 100 hours or every other oil change. Ultimately, it is essential to consider the boat's usage and the quality of the fuel when determining how often to change the fuel water separator filters.

They should be inspected every six months

Water fuel separators should be inspected every six months to ensure optimal performance and prevent engine issues. This is especially important for larger boats, as fuel water separator cartridges are constantly exposed to a moist, salty environment, which can accelerate corrosion and damage. Regular inspections allow for prompt identification and replacement of faulty or worn-out filters, which are crucial for maintaining fuel quality and engine performance.

While some boat owners opt for annual replacements or follow engine hour-based maintenance schedules, semiannual inspections provide an opportunity to identify any potential issues and ensure the filter is functioning correctly. Given the low cost of filters, changing them every six months is a worthwhile investment to protect your engine and avoid costly repairs.

During the inspection, it is essential to check for water accumulation in the fuel water separator. Water entry into the engine can lead to significant performance issues and damage, so it is crucial to address this promptly. Additionally, inspecting the filter for any signs of corrosion or damage is vital to maintain the integrity of the fuel system.

By following a semiannual inspection and replacement schedule, boat owners can have peace of mind knowing that their water fuel separators are in optimal condition. This proactive approach can help prevent unexpected breakdowns and ensure a more reliable boating experience.

Priming new filters with fresh fuel is recommended

Fuel water separator filters should be primed with fresh fuel before installation. This is a good idea because it helps to ensure that the filter is full of fuel and that there is no air in the fuel system. If there is air in the fuel filters or fuel lines, it can cause a vapor lock and prevent the engine from starting.

The process for priming a fuel filter will differ depending on whether the engine is gas or diesel. For a gas engine, turn the ignition key to the accessory position for about five seconds and then turn it back off. Repeat this process three times to prime the new fuel filter with gas. On the fourth attempt, crank the engine and let it run for 15-20 seconds. Turn the engine off and inspect the fuel filter for any signs of gas leaking.

For a diesel engine, place the fuel filter in an upright position and fill it completely with fresh diesel. Wait for the fibers inside the filter to absorb the diesel, then finish filling the filter. Screw the filter tightly onto the fuel filter base. If the top of the housing has a priming bulb, press it in and out with your hand until the bulb no longer moves. Turn the ignition to the accessory position for about 10 seconds, then crank the engine and let it run for about 15 seconds. Turn the engine off and check the filter for any leaks.

It is recommended that fuel water separator filters on boats are changed once a year or every 100 engine hours. However, some people choose to change their filters twice a year or every six months, especially if their boats are exposed to a harsh environment. Filters are relatively inexpensive, and it is advisable to change them regularly to avoid engine problems. Carrying spare filters and a filter wrench is also recommended.

Ethanol in fuel may increase the need to change filters

Ethanol-blended fuel is widely used in Brazil, the United States, and Europe. In the US, most cars can run on blends of up to 15% ethanol, and ethanol represented 10% of the country's gasoline fuel supply in 2011. However, the use of ethanol in fuel does have some drawbacks, and it may increase the need to change filters.

Ethanol is a highly water-soluble alcohol fuel made from grains such as corn and other plant materials. It is hygroscopic, meaning it absorbs moisture from the atmosphere. This can lead to water problems in fuel tanks, which can cause corrosion and other issues. Ethanol also has a lower energy content than gasoline, so engines require additional fuel additives to maintain performance.

The oxidation of ethanol creates corrosive byproducts that can damage engine components over time. It can degrade rubber and plastic parts in engines and fuel lines, leading to costly repairs. Ethanol can also absorb water from the atmosphere, causing it to separate from gasoline and form a corrosive sludge that clogs fuel filters and corrodes metal components. In some cases, fuel tanks have had to be replaced due to ethanol-related damage.

To prevent these issues, it is recommended to use fuel stabilisers and to maintain a full tank of gasoline, especially when storing fuel for extended periods. Regular maintenance and inspections of the fuel system are also essential to mitigate the potential damage caused by ethanol-blended fuel.

While ethanol-blended fuel is here to stay, engine owners should take precautions to minimise potential problems. These include using fuel stabilisers, maintaining fuel systems, and keeping fuel tanks full to prevent water accumulation and phase separation. By taking these steps, the negative effects of ethanol on filters and other engine components can be reduced.

The filter housing and canister should be sprayed with Corrosion X Red to prevent corrosion

Corrosion X Red works by causing common metals and alloys to behave more like noble metals, such as gold and platinum, which are highly resistant to oxidation. It also has dielectric properties, meaning it is safe to use on electronics and can shut down electrolysis between dissimilar metals.

Corrosion X Red is a versatile product with multiple applications, including marine, automotive, agricultural, and industrial uses. It is also environmentally friendly and safe to use. By spraying the filter housing and canister with Corrosion X Red, you can effectively prevent corrosion and keep your fuel water separator functioning optimally.

To ensure the longevity of your fuel water separator, it is essential to maintain it properly. This includes regular inspections, changing the filters as recommended, and taking preventive measures such as spraying with Corrosion X Red. Additionally, priming new filters with fresh fuel, marking the canister with the date and engine hours, and carrying spare filters and a filter wrench are also good practices for maintaining your fuel water separator.
