-12an Inline Fuel Filter - Marine

The -12AN Inline Fuel Filter – Marine by Aeromotive is an essential protection system for any serious boater or angler who demands reliable engine performance on the water. Fuel contamination—whether from old fuel, tank sediment, or water intrusion—can rapidly degrade injectors, carburetors, and fuel pumps, leaving you stranded far from the ramp.

This inline filter intercepts particulates and moisture before fuel reaches your engine's critical systems, ensuring clean, consistent fuel delivery across variable water conditions and extended trips. Engineered for -12AN fitting compatibility, this Aeromotive filter combines compact dimensions (4.85 x 4.15 x 8.85 inches) with robust filtration architecture, allowing it to fit in tight engine compartments without sacrificing flow or protection. The marine-grade construction resists corrosion and salt spray, making it ideal for challenging marine environments.

Anglers and boaters running high-horsepower engines or long-distance cruising rigs benefit most from this filter's protection, particularly when fuel sourcing is uncertain or tank age unknown. Installation is straightforward—mount it inline between your fuel tank and engine using standard -12AN hose and fittings, positioning it for easy access and maintenance.
