EVIL ENERGY 5/16" Fuel Hose 20FT SAE 30R7 NBR - 300 PSI Working Pressure, Oil-Resistant

This reinforced 5/16" (8 mm ID) hose combines nitrile rubber (NBR) compound and braided polyester reinforcement to meet SAE 30R7 standards. With a 20-foot length and a working pressure of 300 psi, it’s designed for reliable delivery of gasoline, diesel, biodiesel blends, oil, grease, and other hydrocarbon-based fluids across a broad temperature range. The hose’s construction emphasizes oil resistance, wear durability and consistent flow characteristics for fuel systems, oil cooling lines and related fluid-transfer tasks.

What are the key performance specs of this 5/16" fuel hose?

The EVIL ENERGY fuel hose offers measurable mechanical and thermal characteristics important for installation and safe operation. Expect a working pressure of 300 psi and a burst pressure approximately 1,200 psi, with a practical operating temperature window.

• Inner diameter: 5/16" (8 mm); outer diameter: 9/16" (14 mm)
• Wall thickness: 3 mm; minimum bend radius: 3.14" (80 mm)
• Working pressure: 300 psi; burst pressure: 1200 psi
• Temperature range: -40°F to 257°F, suitable for cold starts and hot engine compartments

Which fluids and systems is this hose compatible with?

Formulated from NBR (nitrile rubber) and reinforced with braided polyester, the hose resists swelling and degradation from hydrocarbons and related fluids. It is intended for a variety of fuel and oil handling uses without premature deterioration when used as specified.

• Compatible with gasoline, diesel, biodiesel blends, and petroleum-based oils
• Suitable for grease lines and oil cooling circuits where SAE 30R7 hoses are required
• Not for use with strong acids, ketones, or concentrated solvents outside manufacturer guidance

How easy is it to install and route the 20-foot hose?

The hose’s 3.14" (80 mm) minimum bend radius and flexible NBR compound allow straightforward routing through engine bays, machinery frames and equipment cabinets. Use proper clamps and fittings rated to the hose’s pressure and compatible with fuel service.

• 20-foot length reduces joins for long runs; cut-to-fit for custom installations
• Observe minimum bend radius to prevent kinking and flow restriction
• Use push-lock or barb fittings and clamp to SAE-compatible hardware for leak-free connections

What materials and standards does this fuel hose meet?

Constructed to meet SAE 30R7 classification, the hose integrates an oil-resistant NBR inner tube and braided polyester reinforcement for strength and abrasion resistance. These materials provide long service life when used with appropriate fuels and maintained correctly.

• Inner tube: NBR (nitrile rubber) for hydrocarbon resistance
• Reinforcement: braided polyester fiber for pressure capacity and durability
• Delivers SAE 30R7 level performance for fuel system applications

Who is this for: Technicians, mechanics, fleet managers, automotive hobbyists and equipment maintainers who need a dependable, oil-resistant 5/16" fuel line for vehicle fuel systems, oil cooling circuits and small-engine installations. Choose EVIL ENERGY when you want a SAE 30R7-rated NBR hose with a 20-foot length, 300 psi working pressure and broad temperature capability for routine and heavy-duty fuel-transfer tasks.
