Poly Breather Tank w/8an Fitting

The Poly Breather Tank with 8AN Fitting from MOROSO is an essential component for engine builders and performance mechanics focused on effective crankcase ventilation in modified engines. This breather tank captures oil vapor and moisture escaping through the PCV system, preventing fouling of the intake manifold and maintaining air quality in both forced-induction and naturally aspirated applications.

Constructed from durable polyethylene, this breather tank is resistant to cracking and chemical degradation while remaining lightweight to avoid adding unnecessary weight to your engine setup. The 8AN port fitting ensures compatibility with modern high-flow PCV hose systems, allowing for precise plumbing into custom intake or exhaust configurations. The compact dimensions (9.1 x 4.15 x 15.55 inches) and modest weight of 1.13 pounds make it ideal for tight engine bays.

Enthusiasts and mechanics working with turbochargers, superchargers, or high-compression builds will benefit from proper crankcase evacuation, which helps prevent seal failures and oil consumption issues. The internal design of the tank aids in slowing vapor velocity, allowing for effective separation and drain-back to the crankcase, ensuring a clean air charge and reducing overall system pressure spikes.
