P-TRAP BREATHING VALVE 5/8 STYLE 2

The Perko 90° P-Trap breather valve allows fuel vapors to escape from the tank during fuel thermal expansion and allows replacement air to flow into the tank during fuel thermal contraction and while the engine is running. This ensures smooth operation of the fuel system under all conditions. The built-in breather and check valve prevent water from entering the fuel system through the unit. For 5/8 hose.
