Gates Barricade Fuel Injection Hose 25' 5/16" ID — Black, Vapor-Barrier, Heat & Oil Resistant

This hose combines a multi-layer construction with a specialty barrier to reduce fuel vapor permeation, making it suitable for fuel-injection systems and applications where emissions and fuel compatibility matter. It is built to resist oil, heat, ozone and abrasion, and is rated for many gasoline, alcohol and diesel blends used in today's engines.

How does this hose reduce fuel vapor loss?

The Barricade design uses a multi-layer GreenShield barrier that greatly lowers permeability compared with standard rubber hose. That barrier, combined with a fuel-compatible tube, prevents more vapors from escaping, which helps preserve fuel and reduces evaporative emissions.

• Five-layer construction including a thermoplastic barrier.
• Holds lower permeation than conventional single-layer hoses.
• Appropriate for fuel-injection systems where vapor control is important.

Which fuels and blends can I run through this hose?

Gates engineered this hose to accept a wide variety of fuels used in commercial and aftermarket applications. It is compatible with leaded and unleaded gasoline, ethanol blends, methanol, diesel and biodiesel up to common industry concentrations.

• Compatible with E-10, E-15 and E-85 ethanol blends.
• Accepts 100% methanol and gasohol fuel types.
• Works with diesel and biodiesel fuels up to B-100.

What makes the hose durable against heat, oil, and wear?

The outer cover uses a chlorinated polyethylene compound with aramid reinforcement to withstand mechanical wear, surface abrasion and hostile under-hood conditions. Internally, an HNBR tube provides fuel resistance while the overall assembly tolerates elevated temperatures and ozone exposure.

• HNBR inner tube designed for fuel resistance and longevity.
• Aramid fiber reinforcement for pressure and burst strength.
• CPE cover resists oil, heat, ozone and abrasion in service environments.

Does it meet industry standards and where should it not be used?

The Gates Barricade meets SAE 30R14 T2 specifications and complies with CARB and EPA rules for non-road fuel line applications, offering broad regulatory acceptance. Note that while it performs well in many conditions, it is not specified for applications requiring enhanced kink resistance.

• Conforms to SAE 30R14 T2 (except kink resistance specification).
• CARB and EPA acceptable for non-road fuel line use.
• Not recommended where specialized anti-kink properties are mandatory.

Who is this for: The Gates 27340 Barricade hose is suited to mechanics, fleet managers, restorers and performance technicians who need a rugged, low-permeation fuel line that accepts modern fuel blends. Choose this 25' length, 5/16" internal diameter hose when you want broad fuel compatibility, reinforced construction for long service life, and improved control of evaporative losses in fuel-injection or retrofit applications.
