Vent Hose 1 ID x 3ft

The Vent Hose 1 ID x 3ft from ALLSTAR PERFORMANCE is an essential component for proper crankcase ventilation and fuel system management in engine modifications and custom builds. Whether you're upgrading a carbureted engine, installing a catch can system, or routing PCV lines during a full engine swap, this flexible hose delivers reliable performance in demanding automotive applications. Designed for mechanics and enthusiasts who demand consistency across their fuel and emission systems, this 3-foot length accommodates most routing scenarios without requiring multiple splices or adapters.

Constructed with a 1-inch inner diameter, this vent hose maintains adequate flow rates for crankcase breather applications, fuel tank venting, and catch can drain lines while remaining flexible enough to navigate tight engine bay layouts. The durable rubber construction resists oil, fuel, and coolant exposure—critical when routing through high-heat zones near headers or intake manifolds. At 3 feet in length, you gain sufficient material to run from a ported block, valve cover, or fuel tank to external catch cans, charcoal canisters, or atmospheric vents without compromising routing angles or creating kinks that restrict airflow and contamination escape.

This hose is ideal for street rods, race carburetors, forced induction builds, and vintage engine restorations where OEM hose routing is incompatible with modern modifications. Professional mechanics and serious hobbyists rely on ALLSTAR PERFORMANCE components for their engineered reliability and compatibility across domestic and import platforms. The 1 ID (inner diameter) specification ensures proper fitment with standard 1-inch hose barb fittings, breather adapters, and carb vent nipples used in performance fuel systems and emission control bypasses.
