Sierra Fuel Filter & Bowl Assembly Alloy Head Clear Bowl (S18-7932-1)
Complete Fuel Filtration and Water Separation
The Sierra Fuel Filter & Bowl Assembly Alloy Head helps protect your marine engine by removing water and contaminants from the fuel system. Because clean fuel plays a critical role in engine performance, this fuel-water separator captures debris and moisture before they reach sensitive engine components. As a result, it helps maintain smooth engine operation and reduces the risk of fuel-related problems.
High-Performance Filtration
This assembly includes a 10-micron fuel filter, which captures fine particles and contaminants from the fuel supply. Consequently, it improves fuel quality and supports consistent engine performance. In addition, the separator directs water into the clear collection bowl below the filter, allowing you to quickly identify contamination during routine checks.
Clear Bowl for Easy Inspection
The integrated clear fuel bowl allows you to visually monitor the condition of your fuel system at any time. Because the bowl remains transparent, you can easily spot water buildup or debris. Furthermore, the bowl includes a convenient drain so you can remove collected water quickly without removing the entire filter assembly. Therefore, regular maintenance becomes simple and efficient.
Durable Marine Construction
Sierra builds this assembly with a strong aluminium filter head and mounting bracket designed for demanding marine environments. The corrosion-resistant materials withstand exposure to fuel, vibration, and moisture commonly found on boats. As a result, the unit delivers reliable, long-lasting performance for both recreational and commercial vessels.
Complete Kit for Easy Installation
The Sierra S18-7932-1 comes as a complete fuel filter assembly, including the filter element, alloy head, clear bowl, mounting bracket, and fittings. Because it fits many Racor-style fuel systems, it integrates easily into a wide range of marine fuel setups. Ultimately, this all-in-one solution makes it easy to maintain clean fuel and protect your engine on every trip.
