Ruikarhop 5/16" ID Fuel Hose 25ft NBR Rubber SAE 30R7 300 PSI with 10 Clamps — Small Engine Fuel Line

Ruikarhop 5/16" ID Fuel Hose is a 25-foot NBR rubber SAE 30R7 push-lock fuel line rated for 300 PSI working pressure, supplied with 10 clamps for quick installation on small engines and fuel systems.

This professional-grade fuel hose combines a 5/16-inch inner diameter with NBR (nitrile butadiene rubber) construction to resist gasoline, biodiesel blends, lubricants, hydraulic oil and coolant. Built to SAE 30R7 standards, the hose offers a wide temperature range and a high burst pressure, making it suitable for diverse small-engine and light-industrial applications. The package includes ten durable clamps so you can cut and fit the hose to length for motorcycles, lawn equipment, generators and other fuel lines.

Will this hose work with my small engine or lawn mower?

Yes — the 5/16" ID (8 mm) size is commonly used on carbureted small engines, push-lock fittings and fuel petcocks. Confirm your tool’s hose barb matches a 5/16" inner diameter before cutting or connecting. The included clamps support secure attachment to standard fittings and help prevent leaks when installed properly.

• Inner diameter: 5/16 inch (8 mm), outer diameter: 0.63 inch (16 mm)
• Length: 25 ft, cut-to-fit for multiple runs or spares
• Includes 10 metal clamps for fastening to barbs and fittings
• Works with push-lock and barbed connections typical on small engines

How resistant is the NBR rubber to fuels and temperatures?

NBR (nitrile) rubber is formulated for strong resistance to petroleum products, biodiesel blends and many lubricants, making it a practical choice for fuel delivery. The hose tolerates a broad temperature range and has a high burst-pressure rating, but always verify compatibility with specialty fuels or additives before use.

• Compatible with gasoline, unleaded blends, biodiesel, E-10 and some E-85 blends
• Working pressure: 300 PSI; burst pressure: 1160 PSI
• Temperature range: -40°F to 257°F (-40°C to 125°C)
• Resistant to lubricating oil, hydraulic fluids and coolant contact

How should I install and maintain this fuel hose?

Cut the 25-foot hose to the required length with a clean, straight cut and use the supplied clamps to secure it to barbed fittings or push-lock connectors. Routinely inspect connections for chafing, cracks or fuel seepage and replace any section showing wear; proper clamping and routing lengthen service life and reduce leaks.

• Use sharp cutters for a square end to ensure a tight seal
• Tighten clamps to secure but avoid over-torquing and deforming the hose
• Inspect periodically for hardening, cracking, or swelling
• Store spare hose away from sunlight and ozone sources to prevent degradation

What safety and warranty details should I know?

Operate within the listed temperature and pressure ratings and avoid prolonged exposure to fuels or chemicals outside the specified compatibilities. Ruikarhop provides a 3-month warranty for manufacturing defects and invites customers to contact support for any issues with the hose or clamps.

• Do not exceed 300 PSI working pressure in service
• Keep away from open flames and excessive heat exposures
• 3-month warranty against manufacturing defects; contact seller for assistance
• Verify fuel compatibility if using concentrated ethanol or exotic blends
