Breather Tank 8an Male

The Breather Tank 8AN Male by MOROSO is an essential crankcase ventilation component designed for custom engine builds, forced induction systems, and high-performance street or track applications. As an engine management upgrade, it captures blow-by gases and oil vapors that would otherwise contaminate your intake manifold or atmosphere, protecting both engine longevity and emissions compliance. This compact, purpose-built tank serves as a catch-can alternative or secondary reservoir in sophisticated PCV systems where factory crankcase management falls short of your horsepower and reliability goals.

Engineered with an 8AN male fitting port, the Breather Tank 8AN Male integrates seamlessly into custom hose routing and modular plumbing architectures common in turbo, supercharged, and naturally aspirated competition engines. The aluminum construction delivers light weight at just 1.58 pounds while maintaining structural rigidity under pressure cycling and thermal stress typical of boost environments. Its compact footprint—measuring 8.7 by 3.9 by 15.8 inches—permits installation in tight engine compartments where space is at a premium, yet the internal volume provides adequate residence time for oil separation and vapor settling before recirculation or atmospheric venting.

Professionals and serious enthusiasts building LS, small-block Chevy, Ford, Mopar, and import platforms benefit most from this tank when plumbing custom valve covers, supercharger discharge lines, or turbo intercooler piping that demands precision fitting and reliable separation. Installation requires AN fittings and compatible hose rated for your boost level and fluid temperature; mount vertically or at an angle where gravity aids oil return to the engine sump or dedicated drain line. Verify your specific PCV system schematic before ordering to ensure 8AN male threading matches your existing plumbing or planned modifications.
