Black Breather Tank w/-10an Fitting

The Black Breather Tank with -10AN Fitting is an essential component for serious engine builders and street machine enthusiasts who demand proper crankcase ventilation control. This sealed breather system addresses a critical need in high-performance and modified engines where conventional PCV systems fall short. Whether you're running a supercharged small block, a turbocharged stroker, or any engine prone to excessive blowby, this tank provides reliable vapor separation and pressure regulation without compromising engine longevity or cleanliness.

Constructed from durable steel with a satin black powder-coat finish, the Black Breather Tank features a -10AN inlet fitting that integrates seamlessly into custom fuel system layouts and carburetor setups where space is premium. The compact 7.4 x 4.6 x 12.9-inch footprint and lightweight 1.15-pound design allow for flexible engine bay mounting without adding significant weight or requiring extensive fabrication. The tank captures oil mist and condensation from crankcase gases, allowing vapor to escape while containing liquid contaminants—protecting your intake system, fuel mixture, and engine internals from oil fouling and carbon buildup that degrades performance and reliability.

This breather tank is ideal for carbureted applications, bracket racing builds, and restorations where OEM emissions components are deleted or incompatible with engine modifications. Installation works with both naturally aspirated and forced-induction platforms, provided crankcase pressure is managed appropriately upstream. The -10AN fitting accepts standard braided hose and adapters, making plumbing straightforward on custom intake manifolds, valley pan installations, or remote oil catch cans. Proper breather management ensures cleaner combustion, extended engine life, and compliance with basic functional standards on street-driven vehicles.
