EVIL ENERGY 3/8" Fuel Injection Hose 10ft — SAE J30R9 FKM Inner, 300 PSI Working

This 3/8" (9.5mm ID) fuel line delivers a balance of chemical resistance, pressure capacity and temperature tolerance for modern fuel systems. Engineered to exceed SAE J30R9 expectations, the hose combines a fluorine-rubber inner tube with an epichlorohydrin cover and aramid fiber braid for robust durability in fuel delivery, vapor management and oil-cooling applications.

What pressures and temperatures can this hose safely handle?

The EVIL ENERGY 3/8 fuel hose is rated for continuous working pressures up to 300 psi and bursts at around 1200 psi, giving significant safety margin for high-demand fuel injection setups. Its operating temperature range spans from -40°F up to 275°F, with short-term tolerance to about 302°F for intermittent exposure.

• Working pressure: 300 psi
• Burst pressure: ≈1200 psi
• Temperature range: -40°F to 275°F (intermittent to 302°F)
• Minimum bend radius: 2.99 in (76 mm)

Which fuels and systems is this hose compatible with?

Constructed with an FKM inner compound and ECO cover, the hose resists ethanol blends, biodiesel and conventional diesel, making it suitable for performance and retrofit applications. It works across fuel injection lines, fuel filters, tanks, pumps, LS swap plumbing and transmission or oil-cooling lines where SAE J30R9 compatibility is required.

• Compatible with E10, E15, E85, biodiesel and diesel
• Works with fuel injection components and vapor lines
• Suitable for retrofit projects like LS swaps and fuel pump plumbing
• Meets and exceeds SAE J30R9 standard

What are the hose dimensions and construction details I should know?

This hose is sized to 3/8 inch inner diameter (9.5 mm) with an outer diameter of about 0.63 inch (16 mm) and is supplied in a 10-foot length. Construction includes a fluorocarbon (FKM) inner tube for fuel resistance, aramid fiber reinforcement for pressure containment, and an ECO cover for abrasion and weather resistance.

• Inner diameter: 3/8 in (9.5 mm) ±0.4 mm
• Outer diameter: 0.63 in (16 mm) ±0.5 mm
• Length: 10 ft (3.05 m)
• Reinforcement: aramid fiber braid; inner: FKM; cover: ECO

How should I install and maintain this fuel injection hose?

Cut the hose to length with a sharp blade and use clamps or crimp fittings rated for SAE J30R9 service; avoid kinks by respecting the 2.99-inch minimum bend radius. Inspect fittings and the hose regularly for wear, chemical damage or heat degradation and replace if you notice cracking, hardening or leaks.

• Use compatible clamps or factory-style crimp fittings
• Maintain minimum bend radius of 2.99 in (76 mm)
• Inspect periodically for abrasion, heat or chemical degradation
• Replace if hardening, cracking or leaks appear

Who this product is for: Mechanics, tuners and DIY enthusiasts who need a durable, chemical-resistant fuel line for fuel-injected engines, performance swaps (including LS conversions), fuel pumps and vapor management systems. Choose this hose when you require SAE J30R9 performance, compatibility with ethanol blends and a robust construction that withstands high pressure and elevated temperatures.
