EVIL ENERGY 3/8 Fuel Injection Hose 25FT SAE J30R9 — 300 PSI, FKM Inner & Aramid Reinforced

EVIL ENERGY 3/8" fuel injection hose is a 25-foot SAE J30R9-rated line built with an FKM inner, ECO cover and aramid reinforcement for 300psi working pressure and broad fuel compatibility.

This premium fuel line is engineered for modern fuel-injection systems and demanding under-hood environments. It combines fluorine-rubber inner tubing with an epichlorohydrin cover and aramid fiber reinforcement to deliver chemical resistance, heat tolerance, and a high burst rating. The hose meets SAE J30R9 requirements and supports common fuels including gasoline, ethanol blends, biodiesel, and diesel — making it suitable for performance builds, replacements, and conversions.

How does this hose perform under pressure and heat?

The EVIL ENERGY 3/8" hose is rated for 300 psi continuous working pressure with a 1200 psi burst pressure, providing a wide safety margin for fuel-injection and pump-driven systems. Its materials allow operation across a broad temperature window and intermittent exposure to higher temperatures.

• Working pressure: 300 psi for reliable continuous operation.
• Burst pressure: 1200 psi for emergency safety margin.
• Temperature range: -40°F to 275°F regular use, intermittent to 302°F.
• Minimum bend radius: 2.99 inches (76 mm) for compact routing.

What fuels and applications is it compatible with?

Constructed with an FKM inner tube, this hose resists degradation from a wide variety of fuels and additives. It is designed for fuel injection lines but also works well for fuel filters, tanks, pumps, LS swaps, and related plumbing where SAE 30R9 performance is required.

• Compatible with gasoline, ethanol blends (E10, E15, E85), biodiesel, and diesel.
• Suitable for fuel injection systems, fuel pumps, filters, and tank lines.
• Accepts use in vapor emission and oil-cooling pathways where SAE R9 specs apply.
• Works with other SAE 30R6 and 30R7 applications when higher chemical resistance is needed.

What are the hose dimensions and installation considerations?

The line ships as a continuous 25-foot length with a nominal inside diameter of 3/8" (9.5 mm) and an outside diameter near 0.63" (16 mm). Tolerances are included to assist fitment; measure fittings and clamps carefully for secure, leak-free connections.

• Inside diameter: 3/8" (9.5 mm), tolerance ±0.4 mm.
• Outside diameter: 0.63" (16 mm), tolerance ±0.5 mm.
• Length: 25 feet of continuous hose for multiple runs or cutting to size.
• Minimum bend radius: 2.99" (76 mm) to avoid kinks or flow restriction.

Why choose SAE J30R9 construction for a fuel-injection project?

SAE J30R9 is a widely accepted specification for fuel-injection lines that demand higher heat and chemical resistance than generic hoses. Choosing an R9-rated hose reduces the risk of premature swelling, hardening, or failure when exposed to modern fuel blends and elevated engine-compartment temperatures.

• Meets and exceeds SAE J30R9 standards for fuel-injection service.
• FKM inner tube improves resistance to alcohols and aggressive fuels.
• Aramid fiber reinforcement delivers improved burst and abrasion resilience.
• ECO cover offers durable external protection against heat and ozone.

Who is this for: Installers, tuners, and DIY mechanics who need a durable, fuel-compatible hose for performance engines, LS swaps, or replacements in modern fuel systems will appreciate this EVIL ENERGY 3/8" SAE 30R9 line. It’s aimed at anyone who requires a long continuous length (25 ft) with proven material performance and clear dimensional specs for dependable routing and secure connections.
