YAMAKATO fuel line hose 10 ft 5/16 in — oil & ethanol resistant with 20 steel clamps

The YAMAKATO 10-foot, 5/16-inch inner diameter rubber fuel line kit is a flexible, oil- and ethanol-resistant hose bundle supplied with twenty steel clamps for cutting-to-fit fuel, vapor, and vacuum routing on small engines.

This kit is designed for hobbyists, mechanics, and small-engine owners who need a durable replacement or extension of low-pressure fuel and vapor lines. It is intended for non-pressurized systems—carbureted lines, gravity-feed fuel arrangements, vapor recovery, and vacuum smog hoses—on equipment such as lawnmowers, generators, motorcycles, tractors, and other similar machines. The hose’s double-compound construction balances stretch and strength while offering wide temperature tolerance.

How does this hose handle different fuels and temperatures?

The rubber compound used in the YAMAKATO line resists oils and ethanol blends commonly found in small-engine fuels, and it tolerates a broad temperature range from -22°F to 338°F. That makes it suitable for outdoor equipment exposed to cold starts and hot engine bays, as long as it’s used in non-pressurized applications. Avoid using this hose where a pressurized fuel pump is present.

• Compatible with gasoline and diesel vapors and ethanol blends (ethanol tolerance).
• Temperature range: -22°F (-30°C) to 338°F (170°C).
• Oil-resistant construction for longer service life around engines.

Will the length and diameter fit my small engine project?

The kit comes as a single 10-foot continuous length with a 5/16-inch (8.0 mm) inner diameter and an approximately 9/16-inch (14 mm) outer diameter—dimensions that match many OEM small-engine hoses. The extra length allows you to trim the hose to the exact size you need, and the included clamps secure cut ends quickly.

• One 10-foot (3.05 m) continuous hose allows multiple cuts or long runs.
• Inner diameter: 5/16 inch (8.0 mm); outer diameter: ~9/16 inch (14 mm).
• Includes twenty steel hose clamps (13.7 mm inner clamp diameter) for immediate installation.

Is this hose suitable for pressure fuel systems or inline pumps?

No—this product is specified as a non-pressure fuel line (not a reinforced high-pressure hose). It is intended for gravity-feed or vacuum lines and will not withstand the higher pressures produced by many in-line fuel pumps or pressurized fuel-injection systems. For pressurized applications, select a hose rated for your system’s maximum pressure.

• Not rated for high-pressure fuel pump systems—use only in non-pressurized circuits.
• Recommended for carbureted engines, vapor/emission lines, and vacuum smog control lines.
• Double-layer compound for durability under flexing, not for pressure sealing.

What comes in the box and how easy is it to install?

The package contains one 10-foot length of YAMAKATO fuel hose plus twenty steel plate hose clamps sized for the hose’s diameter. Installation requires simple cutting tools and a screwdriver to tighten clamps; you can cut sections to fit multiple machines or replace worn segments. Clamp placement and hose routing should follow your engine maker’s recommendations to avoid kinks and chafing.

• Included items: one 10 ft hose and 20 steel hose clamps.
• Tool needs: utility knife or hose cutter, screwdriver or nut driver for clamps.
• Installation tip: leave slight slack and avoid tight bends to preserve flow.

Who is this for? This YAMAKATO hose kit is a practical choice for DIYers, small-engine repair shops, landscapers, and vehicle owners who need a reliable non-pressure fuel or vapor line solution. It’s particularly useful when you need extra length to custom-fit multiple machines or to stock a workshop with a single, cut-to-size supply. If your application requires pressurized lines, select a product rated for pressure instead.
