Vacuum Pump Breather Tank 2-Breathers -16A

The Vacuum Pump Breather Tank 2-Breathers -16A by Moroso is an essential component for high-performance engine builders and street rodders looking to manage crankcase pressure effectively. This breather tank serves as a critical interface between your engine's PCV system and the atmosphere, preventing pressure buildup while keeping oil mist and contaminants out of your intake manifold. Proper crankcase ventilation directly impacts ring seal integrity, oil consumption, and overall engine longevity.

This Moroso unit features dual -16AN breather ports that accommodate 16-size hose fittings, allowing for flexible routing of vacuum lines. The two-breather design separates crankcase ventilation and vacuum recovery—one line can feed a vacuum pump for scavenging, while the second provides gravity or check-valve venting. The tank's welded aluminum construction resists corrosion and vibration while remaining lightweight, and its internal baffle design minimizes oil carryover into vacuum systems.

Experienced engine tuners favor this tank for its effectiveness in maintaining proper crankcase ventilation, especially in setups where positive crankcase pressure is a concern. Its compact footprint of 10.5 x 7.85 x 12.45 inches allows it to fit into engine bays without consuming excessive space. This makes it suitable for various applications, including street rods and muscle cars.
