EVIL ENERGY 1/4" NBR Fuel Hose 25FT SAE 30R7 — 300 psi Working Pressure, -40°F to 257°F

This 25-foot push-lock fuel hose from EVIL ENERGY combines nitrile rubber (NBR) inner tubing with a braided polyester reinforcement to meet SAE 30R7 performance expectations. Engineered for fuel-system and oil-cooling applications, the hose balances flexibility, chemical compatibility and mechanical strength while tolerating temperatures from -40°F to 257°F. The 1/4" inner diameter (6mm) and compact 0.47" outer diameter (12mm) make it suitable for tight routing on engines, pumps and workshop rigs.

How durable is this fuel hose under pressure and heat?

The hose is rated for a working pressure of 300 psi and a burst pressure up to 1200 psi, giving a wide safety margin for most vehicle and equipment fuel lines. NBR construction resists swelling and degradation from hydrocarbons, while the polyester braid improves tensile strength and abrasion resistance.

• Working pressure: 300 psi for continuous use
• Burst pressure: 1200 psi for safety reserve
• Temperature tolerance: -40°F to 257°F for cold-starts and high-heat environments
• Reinforced braid reduces kinking and improves longevity

Will this hose work with my fuel types and fluids?

The inner NBR (nitrile) compound is formulated for compatibility with a broad range of hydrocarbon-based fluids, including gasoline, diesel and biodiesel blends. It also handles oils and greases commonly found in automotive and industrial systems, making it a versatile replacement line.

• Compatible with gasoline, diesel and biodiesel
• Suitable for oil, grease and many petroleum-based fluids
• Not intended for strong solvents or incompatible chemicals
• Meets SAE 30R7 guidelines for fuel hose applications

How flexible and easy is it to install in tight spaces?

With an inner diameter of 1/4" (6mm), outer diameter of 0.47" (12mm) and 3mm wall thickness, this hose is compact and bends easily around engine bays and pump fittings. The listed minimum bend radius of 2.36" (60mm) helps installers plan routing to avoid sharp kinks and preserve flow.

• ID/OD: 1/4" (6mm) / 0.47" (12mm) for compact routing
• Wall thickness: 3mm for durability without bulk
• Minimum bend radius: 2.36" (60mm) to prevent pinching
• Push-lock friendly with common clamps and fittings

What applications is this hose best suited for?

Designed to meet and exceed SAE 30R7 standards, the EVIL ENERGY fuel hose is appropriate for vehicle fuel systems, oil cooling lines, fuel transfer operations and general-purpose shop use. Its chemical resistance and pressure ratings make it useful wherever a reliable petroleum-compatible hose is required.

• Automotive and motorcycle fuel lines
• Oil cooling and lubrication circuits
• Fuel transfer and service shop setups
• Small engines, generators and marine fittings (as allowable)

Who is this for? If you need a compact, oil-resistant fuel hose for automotive, industrial or workshop use—especially when space is limited and reliability matters—this 25-foot EVIL ENERGY SAE 30R7 hose offers a balanced combination of chemical compatibility, pressure capacity and flexibility. It's aimed at mechanics, fabricators, fleet technicians and DIYers who require a dependable replacement or custom-length fuel line that conforms to recognized SAE specifications.
