Gates Barricade Carburetion Fuel Hose 25 ft, 1/4" ID — GreenShield 5-Layer Low-Permeation, Heat & Ozone Resistant

Gates 27313 Barricade Carburetion Hose is a 25-foot, 1/4" inner-diameter fuel line designed with Gates' five-layer GreenShield technology to reduce fuel vapor permeation and resist heat, ozone, and aggressive fuels.

This premium fuel hose is engineered for modern engines and refined fuel blends that need superior containment and durability. Built with multiple protective layers—including a patent-pending thermoplastic Greenshield barrier and a reinforced textile spiral—this hose delivers industry-leading low permeation, strong working pressure, and resistance to environmental stressors. It's suitable for many carburetion and fuel system applications where reduced emissions, longer service life, and dependable performance matter.

How does this hose reduce fuel vapor and emissions?

The Gates Barricade hose incorporates a Greenshield thermoplastic barrier plus a fortified barrier tube to minimize vapor diffusion. Together these layers create up to five times less permeation than the closest competitor, helping contain volatile compounds and extend component life.

• Patented five-layer GreenShield construction reduces permeation markedly.
• Thermoplastic Greenshield layer acts as the primary vapor barrier.
• Barrier tube adds secondary protection against aggressive fuels and heat.

Will this hose stand up to heat, ozone, and modern fuels?

Yes. The outer cover resists ozone and elevated temperatures while the adhesion layer and reinforced tube resist oil and aggressive fuel blends. These combined defenses help the hose maintain integrity under demanding operating conditions.

• Cover designed for outstanding ozone and heat resistance.
• Adhesion layer provides extra defense against oil and additives.
• Barrier tube fortified to withstand high heat and aggressive fuel chemistries.

What about pressure handling and physical strength?

Gates engineered the hose with a textile spiral reinforcement that yields a best-in-class working pressure of 50 PSI, offering reliable performance for many carbureted and low-pressure fuel systems. The construction balances flexibility and strength for easy routing without sacrificing durability.

• Textile spiral weave reinforcement for robust structural support.
• Rated working PSI of 50 for dependable fuel delivery under pressure.
• Flexible enough for tight installations while resisting collapse or kinks.

How do I choose and use the 25' x 1/4" Gates Barricade hose?

Select this size when your application requires a 1/4" inner diameter run and you need enough length for routing, splicing, or inventory. Cut to length with a clean, straight cut and use compatible clamps and fittings rated for fuel systems. Inspect fittings and hose ends after installation and periodically check for chafing or wear.

• Use 1/4" ID for carburetor feed lines, return lines, and similar low-pressure runs.
• Trim with a fine-toothed saw or hose cutter for a clean end; secure with fuel-rated clamps.
• Perform routine inspections for abrasion, kinks, or clamp failures.

Who is this for: Technicians, restorers, performance hobbyists, and fleet maintenance teams who need a durable, low-permeation fuel hose for carburetion and low-pressure fuel systems. If you work with modern fuel blends or require improved vapor containment and resistance to heat and chemicals, the Gates 27313 Barricade hose delivers a practical, long-lasting solution with professional-grade reinforcement and patented Greenshield technology.
