Breather Tank 1qt w/10an Fitting - Poly - Black

The MOROSO Breather Tank 1qt with 10AN Fitting in black polymer is a compact overflow recovery system designed for high-performance engines where crankcase pressure management and fluid containment are critical. This bolt-on breather tank captures excess oil vapor and coolant overflow, preventing contamination of engine bays and reducing environmental spillage during aggressive driving, off-road operation, or marine service where fluid loss can compromise performance and stealth.

The 1-quart capacity addresses fluid recovery without adding excessive weight or bulk to the engine compartment. The 10 AN bulkhead fitting provides a standardized, high-flow connection point compatible with professional-grade hose systems and adapters used in custom engine builds and racing applications. The molded plastic construction resists corrosion in salt-air environments and minimizes thermal conductivity, reducing heat transfer to stored fluids. The included breather element filters incoming air, while the petcock drain valve enables quick fluid evacuation without disconnecting hoses, critical during field maintenance or rapid fluid changes.

This configuration suits operators running modified powerplants in trucks, off-road recovery vehicles, marine engines, or motorsports platforms where factory overflow tanks are inadequate or unavailable. The compact 3.125-inch diameter and 10.5-inch height fit tight engine bays and custom frame layouts where space is restricted. Users managing high-boost pressure systems, extended trail operations, or offshore duty benefit from active fluid containment that keeps engine compartments clean and prevents environmental liability.

MOROSO breather tanks are OEM-level components trusted in circle track racing, drag racing, and marine racing where reliability under sustained pressure is non-negotiable. This 1-quart model strikes a balance between capacity and footprint, making it suitable for street-modified vehicles and light-duty performance applications where overflow events are occasional but must be managed without fluid loss.
