Review ENGINEERED MARINE PRODUCTS Filter Fuel Water Separator

The Marine 35-37803 Fuel Water Separator is a crucial component for ensuring the optimal performance and longevity of marine fuel systems. This separator is designed to remove water and other contaminants from marine diesel fuel, preventing damage to engine components caused by water ingression.

The separator housing is made from high-density polyethylene (HDPE), a durable and corrosion-resistant material, ensuring long-lasting use even in harsh marine environments. The unit features a 3/4-inch inlet and outlet connection, making it compatible with standard marine fuel lines.

The separator employs a pleated paper element with a micron-rated filtration media that effectively separates water droplets and other contaminants from the fuel. The element has a large filtering surface area, allowing for extended periods between filter replacements, reducing maintenance requirements.

Additionally, the Marine 35-37803 Fuel Water Separator comes with a clear sight glass, enabling easy visual inspection of the element's condition. A built-in water drain valve allows for easy and convenient drainage of accumulated water, ensuring the element remains dry and free of contaminants.

The separator also includes a bypass valve, which can be used to bypass the filtration element during engine start-up or in case of filter clogging, ensuring uninterrupted fuel flow to the engine. The valve is adjustable, allowing users to fine-tune the bypass settings for their specific fuel system.

The unit is designed with easy installation in mind, with mounting brackets and hardware included for simple attachment to the fuel line. The Marine 35-37803 Fuel Water Separator is suitable for use in a wide range of marine applications, from small pleasure boats to large commercial vessels, making it a versatile and essential addition to any marine fuel system.

The Marine 35-37803 Fuel Water Separator is a crucial component in the fuel system of marine engines, helping to ensure the engine runs efficiently by separating water from the fuel. Here are some pros and cons of buying this fuel water separator:
