Black Breather Tank w/-12an Fitting

The Black Breather Tank w/ -12AN Fitting is a purpose-built overflow and air management system designed for high-performance fuel systems in tactical vehicles, race platforms, and specialized military equipment. This 1-quart capacity breather tank eliminates pressure buildup in fuel cells and allows controlled air intake during fuel consumption, preventing vapor lock and fuel starvation—critical concerns in vehicles operating under extreme conditions, prolonged idle, or rapid acceleration cycles. Operators and technicians rely on breather tanks to extend fuel system longevity and maintain consistent pressure delivery to fuel pumps, especially in sealed or pressurized fuel systems.

The Black Breather Tank features a 4-inch diameter by 12-inch tall molded plastic construction that resists corrosion and vibration stress common in vehicle environments. The -12AN male inlet fitting ensures compatibility with standard high-pressure fuel line systems and allows quick, secure connection without adapters. An integrated ball valve drain simplifies maintenance by enabling rapid tank evacuation and servicing without complete system disassembly. The tank arrives equipped with a built-in breather element that filters incoming air, removing contaminants and moisture that could compromise fuel purity and injector performance. Compact dimensions (7.6 x 4.6 x 12.5 inches) and lightweight construction (1.35 lbs) make installation feasible in space-constrained engine bays or auxiliary fuel system configurations.

Military mechanics, tactical vehicle maintainers, and performance fuel system builders integrate this breather tank into applications ranging from fuel cell overflow lines to remote fuel storage systems in off-road and emergency response vehicles. The -12AN fitting accepts standard braided hose and compression fittings, simplifying retrofits and repairs in field conditions. Installation typically positions the tank above fuel cell level to utilize gravity-assist drainage and ensure reliable breather operation across all vehicle attitudes. Verification of breather element compatibility with fuel type (gasoline, diesel, or synthetic blends) ensures optimal filtration performance and extends service intervals between maintenance cycles.
