Moroso 85390 Tank Breather Vacuum Pump with Dual Breathers

The Moroso 85390 is a tank breather vacuum pump system designed for high-performance racing applications. This vacuum pump breather system helps maintain proper crankcase pressure while preventing oil contamination and reducing emissions from your oil tank or dry sump system.

Key Features:

• Dual breather configuration for increased venting capacity
• Vacuum pump design creates negative pressure in the oil tank
• Helps reduce oil aeration and foaming in high-performance engines
• Prevents oil mist and vapor from escaping the breather system
• Commonly used with dry sump oiling systems and racing oil tanks
• Durable construction designed for extreme racing conditions

This breather system is ideal for drag racing, road racing, and other motorsports applications where maintaining proper oil tank pressure is critical for performance and reliability. The dual breather design provides superior venting compared to single breather systems, making it well-suited for high-horsepower engines that generate significant crankcase pressure.
