Key Features

 Spin-on Design: This is a one-piece metal canister filter. Simply unscrew the old filter and replace it with the new one, making it extremely easy to operate and convenient for quick maintenance in marine environments.

 Filtration and Waterproofing:

 Its core function is to separate free water from diesel fuel. The filter element typically features a water collection trough (transparent or metal) at the bottom, allowing accumulated water to be visible.

 Built-in float-type water level sensor. When the water level reaches a certain level, the sensor triggers a circuit that illuminates a warning light on the instrument panel, alerting the crew to manually drain the water.

 It also filters solid particles (such as rust, dust, and microorganisms) from the diesel fuel.

 Robust Construction: The all-metal construction withstands the vibration, corrosive environment, and fuel pressure of marine environments.

 Primary Filtration: Typically used as a primary filter (pre-filter) or oil-water separator in a fuel filtration system, it serves as the first line of defense to protect downstream precision filters and the expensive fuel injection system.

Important Notes

1. Manual Draining: This is the most critical maintenance operation for this filter element. When the warning light illuminates, you must immediately open the drain valve at the bottom of the filter to drain the water. Otherwise, water will enter the engine and cause serious damage.

2. Replacement Interval: The replacement interval should strictly follow the engine manufacturer's recommendations, which are usually based on engine operating hours. Do not use beyond the recommended period, as a clogged filter element will cause the engine to lose power or even fail to start.

3. Compatibility and Quality:

 When purchasing a replacement, be sure to confirm that its size, thread connections, and seals are identical to the original.

4. Installation Note: When replacing a new filter element, apply a small amount of new diesel fuel to the seal to lubricate it and prevent damage when tightening. After installation, start the engine and check for leaks.

Summary: The 7670016 is a marine diesel prefilter/oil-water separator with a water level alarm. Its core function is to protect the marine engine fuel system from water and impurities. Regular manual draining and timely replacement are key to ensuring proper function.
