Vent Hose 1.25 ID x 5ft

The Vent Hose 1.25 ID x 5ft from ALLSTAR PERFORMANCE is a critical overflow and pressure relief line for fuel cell systems, custom fuel tanks, and high-performance engine builds. Whether you're constructing a race car, restoration project, or fuel system upgrade, this vent hose allows safe venting of fuel vapors and pressure buildup while preventing fuel spillage during acceleration, braking, and cornering. Mechanics and fabricators rely on properly sized fuel cell vent lines to meet safety regulations and prevent fuel starvation or tank damage in demanding driving conditions.

This fuel cell vent hose features a 1.25-inch inner diameter and extends 5 feet in length, providing sufficient routing flexibility through engine bays and frame rails during installation. The clear vinyl construction allows visual inspection of fuel vapor condensation and blockages, helping you identify potential clogs or moisture accumulation that could impede venting. Vinyl material resists gasoline and common fuel additives while remaining flexible for tight bends and complex routing paths. The seamless design minimizes leakage points and delivers consistent airflow under both static and dynamic conditions, ensuring your fuel tank maintains proper atmospheric pressure regardless of fuel level or driving intensity.

This vent hose is essential for street rods, race cars, swap projects, and fuel cell conversions where OEM vent systems are removed or incompatible. The 1.25-inch diameter accommodates most fuel cell overflow specifications and pairs seamlessly with fuel cell vents, catch cans, and charcoal canister systems. Installation requires cutting and securing the hose with clamps at connection points—standard hose barbs and fittings accept 1.25-inch ID tubing. For maximum safety and performance, ensure vent lines run uphill from the fuel tank to prevent fuel siphoning, and terminate in a safe location away from driver compartments and hot engine components.
