Breather Tank Vac-Pump

The Breather Tank Vac-Pump by MOROSO is a precision-engineered crankcase ventilation solution designed for high-performance engine builders and serious automotive enthusiasts. This bolt-on breather tank addresses the critical need to safely evacuate crankcase vapors and pressure while maintaining a sealed engine environment. By capturing blow-by gases and condensation, the Breather Tank Vac-Pump protects internal engine components from moisture damage and helps maintain consistent oil condition—essential for extended engine life and reliable performance.

Constructed from aluminum for lightweight durability, this 1-quart capacity tank features a 3.125-inch diameter and 11.5-inch height, optimized for compact engine bay integration. The unit incorporates a 12 AN male inlet connection for secure high-flow hose attachment, a petcock drain valve for easy maintenance and fluid recovery, and a split mounting clamp system that simplifies installation without extensive fabrication. The included breather element provides effective filtration of escaping vapors while preventing external contaminants from entering the crankcase, maintaining system integrity under varying engine loads and temperatures.

The Breather Tank Vac-Pump suits vintage restorations, street performance builds, and racing applications where factory PCV systems prove inadequate or restrictive. Its aluminum construction in natural finish provides corrosion resistance while maintaining a professional appearance under the hood. Installation requires only basic hand tools and a suitable mounting location; the split clamp accommodates various frame and chassis configurations. Whether upgrading a carbureted small-block or managing excessive blow-by in a forced-induction engine, this tank delivers reliable crankcase management with minimal installation complexity.
