Vent Hose 1.50 ID x 20ft

The Vent Hose 1.50 ID x 20ft from Allstar Performance is an essential component for engine builders, custom fabricators, and serious enthusiasts managing crankcase ventilation and fluid transfer systems. Whether you're routing PCV lines, overflow hoses, or coolant bypass passages in a modified engine bay, this industrial-grade hose delivers the flexibility and durability needed for high-performance applications. At 20 feet in length, it supplies enough material for complex custom layouts without excessive splicing, saving time and reducing potential leak points in your build.

Constructed with a 1.50 inch inner diameter, this vent hose accommodates moderate flow rates typical of crankcase evacuation, fuel tank vent systems, and overflow applications without excessive backpressure or restriction. The robust construction resists kinking and maintains its shape through tight engine compartment routing, critical when working around headers, turbochargers, and tight accessory mounting zones. Allstar Performance's materials engineering ensures compatibility with fuel vapors, coolant mixtures, and crankcase blow-by gases, making it suitable for both naturally aspirated and forced-induction platforms where reliability cannot be compromised.

Mechanics and fabricators building LS engines, big-block Chevys, or street rods trust this hose for routing catch-can systems, custom overflow tanks, and PCV manifold feeds. The 20-foot length is ideal for engine swaps where factory locations no longer apply and custom pathways through the frame or auxiliary panels become necessary. Cut to length as needed, this hose integrates seamlessly with standard barbed fittings and clamp systems, ensuring a professional appearance and leak-free operation across thousands of miles of hard use.
