Review VETUS Fuel Overflow Splash Stop

Introducing the Vetus FS3816 Fuel Splash Kit and the accompanying FS383851 Filter, two essential components designed to enhance the performance and reliability of marine diesel engines.

The Vetus FS3816 Fuel Splash Kit is a meticulously engineered system that addresses the issue of fuel slosh and starvation in marine diesel engines. This kit includes a fuel splash plate and a fuel distributor. The fuel splash plate is mounted to the engine's fuel tank and is designed to direct fuel towards the engine's inlet during heavy load conditions or when the boat is at rest. This ensures an even fuel distribution to the engine, preventing fuel starvation and improving engine performance.

The fuel distributor, on the other hand, is responsible for atomizing the fuel and delivering it to the engine's injection pump. The Vetus FS3816 fuel distributor is made from high-quality materials, ensuring durability and resistance to corrosion, even in the harsh marine environment. Its unique design ensures an optimal fuel flow rate, which translates to better combustion and increased engine efficiency.

The Vetus FS383851 Filter is an essential companion to the Fuel Splash Kit. This filter is designed to remove any impurities or contaminants from the fuel before it reaches the engine. The filter features a large micron rating, ensuring that even the smallest particles are captured, preventing damage to the engine and improving its longevity. Its robust construction ensures that it can withstand the rigors of the marine environment, making it a reliable and long-lasting addition to your engine system.

In conclusion, the Vetus FS3816 Fuel Splash Kit and the FS383851 Filter are two critical components that work together to improve the performance and reliability of marine diesel engines. The fuel splash plate and distributor ensure an even fuel distribution, preventing fuel starvation, while the filter removes impurities and contaminants, protecting the engine from damage. Together, these products make an excellent investment for boat owners who value the smooth and efficient operation of their marine diesel engines.

The Vetus FS3816 and FS383851 are two fuel lift pumps manufactured by Vetus Marine. Both pumps are designed to provide reliable fuel supply to marine engines, but they have some differences that might influence your purchasing decision.

1. Compact design: With a diameter of only 110mm, the FS3816 is relatively small, making it a good choice for boats with limited space.

2. Low noise level: This fuel lift pump operates at a lower noise level compared to some other models, which can be a significant advantage for those who value quiet operation.

3. Suitable for both diesel and gasoline engines: The FS3816 can be used with both diesel and gasoline engines, making it a versatile option for boat owners.

1. Limited flow rate: Compared to the FS383851, the FS3816 has a lower flow rate, which might not be sufficient for larger engines or high-demand applications.

2. Not suitable for high-altitude installations: The FS3816 is not recommended for installations above 3,000 feet (915 meters) above sea level due to its lower atmospheric pressure compensation.

1. Higher flow rate: The FS383851 has a higher flow rate than the FS3816, making it a better choice for larger engines or high-demand applications.

2. Suitable for high-altitude installations: This fuel lift pump can be used in installations up to 10,000 feet (3,048 meters) above sea level due to its atmospheric pressure compensation.

1. Larger size: The FS383851 has a larger diameter (130mm) than the FS3816, which might make it less suitable for boats with limited space.

2. Higher noise level: This fuel lift pump operates at a higher noise level compared to the FS3816, which can be a disadvantage for those who value quiet operation.

1. Size and space availability on your boat

2. Engine size and fuel demand

3. Desired noise level

4. Altitude of your installation

If you have a smaller engine, limited space, and value quiet operation, the Vetus FS3816 might be the better choice. However, if you have a larger engine, high fuel demand, or need to install the pump at high altitude, the Vetus FS383851 would be a more suitable option.

Based on these considerations, I would recommend the Vetus FS3816 for smaller boats with limited space and quiet operation as a priority. However, if you have a larger engine, high fuel demand, or need to install the pump at high altitude, the Vetus FS383851 would be the more suitable choice.
