EVIL ENERGY 1/4-in Fuel Hose 10ft SAE 30R7 NBR — 300 PSI Flexible Braided Line

EVIL ENERGY 1/4" Fuel Hose is a 10-foot NBR SAE 30R7-rated line designed for diesel, gasoline, biodiesel and oil applications at up to 300 PSI.

This premium fuel hose combines nitrile-butadiene rubber (NBR) with a braided polyester reinforcement to deliver a balance of flexibility, chemical resistance and mechanical strength. Built to meet SAE 30R7 standards, the hose is sized for tight routing and compact installations while offering a broad temperature range for seasonal and off-road use.

What materials and dimensions define this fuel line?

The hose core is NBR (nitrile rubber) for fuel resistance, wrapped in braided polyester fiber for tensile strength. Inner and outer dimensions, wall thickness and bend radius are tuned for small-diameter fuel system runs.

• Inner diameter (ID): 1/4" (6 mm)
• Outer diameter (OD): 0.47" (12 mm)
• Wall thickness: 3 mm
• Minimum bend radius: 2.4" (60 mm)

How durable is the hose under pressure and temperature extremes?

Designed for automotive and light industrial fuel lines, the hose supports sustained working pressures and tolerates significant temperature swings. Burst pressure is rated substantially higher than working pressure to provide built-in safety margin.

• Working pressure: 300 PSI for typical fuel and oil circuits
• Burst pressure: 1200 PSI, four times the working pressure
• Temperature range: -40°F to 257°F (-40°C to 125°C)

Which fluids and systems is this fuel hose compatible with?

The NBR compound and polyester braid make the hose suitable for a wide range of hydrocarbon-based fluids and related applications. It’s optimized for fuel transfer and oil system connections where SAE 30R7 compatibility is required.

• Compatible with gasoline, diesel, biodiesel blends, motor oil and many lubricants
• Suitable for fuel systems, oil cooling lines, fuel return lines and low-pressure deliveries
• Not intended for high-pressure hydraulic brake lines or oxygen service

How will this hose fit into my installation and what accessories pair well?

The 1/4" ID and 10-foot length make this hose a practical choice for routing in compact engine bays and modular equipment. Its flexible NBR construction simplifies bends while the braided reinforcement resists kinking and abrasion.

• Length: 10 feet (cut to fit on-site for custom runs)
• Pairs with 1/4" push-lock fittings, barbed hose ends and standard clamps
• Minimum bend radius gives guidance for routing and clamp placement

Who this product is for: technicians, mechanics and DIYers who need a reliable small-diameter fuel line that balances fuel compatibility, temperature tolerance and mechanical strength. Ideal for automotive restorations, diesel engine work, small equipment fuel systems and custom installations where SAE 30R7 performance, a 1/4" ID and a 10-foot length are required. If you need a different length or a special fitting, cut-to-fit customization and standard push-lock connectors are commonly used with this hose.
