EVIL ENERGY 5/16 Fuel Hose 20 ft — SAE 30R7 NBR Push-Lock, 300 PSI Oil-Resistant

EVIL ENERGY 5/16" SAE 30R7 NBR fuel hose is a 20-foot, oil-resistant push-lock line rated for 300 psi working pressure, built for diesel, gasoline, biodiesel and other hydrocarbon fluids.

Designed to meet and exceed SAE 30R7 requirements, this 5/16" (8mm) ID hose combines a nitrile-butadiene rubber (NBR) tube with braided polyester reinforcement to deliver fluid compatibility, abrasion resistance and reliable performance across a broad temperature span. With a 9/16" (14mm) outer diameter, 3 mm wall thickness and a compact 3.14" (80 mm) minimum bend radius, the EVIL ENERGY hose is intended for fuel systems, oil cooling lines, steam-emission recovery and general hydrocarbon transfer where a flexible, durable line is needed.

How durable is the hose under pressure and heat?

The hose is rated for a 300 psi working pressure and a 1200 psi burst pressure, giving a wide safety margin for typical fuel-system use. The NBR compound resists oil and hydrocarbon degradation while the braided polyester reinforcement controls expansion under pressure and improves abrasion tolerance.

• Working pressure: 300 psi; burst pressure: 1200 psi
• Temperature range: -40°F to 257°F (-40°C to 125°C)
• Reinforcement: braided polyester fiber for pressure stability
• Wall thickness: 3 mm reduces wear and puncture risk

What fluids and environments is this hose compatible with?

The inner NBR tube is formulated for resistance to diesel, gasoline, biodiesel blends, oil and grease, making it suitable for most engine and fuel-handling applications. It is not intended for aggressive chemicals outside the hydrocarbon family; verify compatibility for specialty fluids before use.

• Compatible: gasoline, diesel, biodiesel, engine oil, grease
• Not recommended: strong acids, caustics, or certain solvents without testing
• Meets SAE 30R7 standards for fuel and oil service
• Good resistance to abrasion and oil-induced swelling

How does the hose install and what are its dimensional details?

The 20-foot push-lock line uses standard 5/16" fittings and clamps for a quick, leak-resistant installation on fuel rails, pumps, filters and tanks. Its 3.14" minimum bend radius and compact outer diameter help route the hose through confined engine bays while maintaining flow and preventing kinks.

• Inner diameter (ID): 5/16" (8 mm); outer diameter (OD): 9/16" (14 mm)
• Minimum bend radius: 3.14" (80 mm) to avoid kinks
• Length: 20 ft (6.1 m) continuous hose for longer runs
• Wall thickness: 3 mm for durability and pressure handling

What construction and standards back its performance?

Construction pairs an NBR inner liner with a braided polyester reinforcement and an oil-resistant outer cover to keep the hose flexible yet robust. Conformance to SAE 30R7 ensures that materials, pressure ratings and fluid compatibility meet industry expectations for fuel and oil service.

• Inner tube: nitrile-butadiene rubber (NBR) optimized for hydrocarbons
• Reinforcement: braided polyester fiber reduces elongation under load
• Outer cover: oil- and wear-resistant formulation
• SAE 30R7 standards compliance for fuel/oil hoses

Who is this for? EVIL ENERGY's 5/16" SAE 30R7 NBR 20-foot fuel hose is aimed at mechanics, fleet operators, custom fabricators and DIY automotive enthusiasts who need a trustworthy, oil-resistant line for fuel systems, oil cooling circuits and related hydrocarbon transfers. If your project requires a compact-diameter hose that resists oil degradation, holds steady under pressure and fits tight routing channels, this hose delivers a balanced blend of flexibility, durability and industry-standard safety margins.
