EVIL ENERGY 3/8 Fuel Hose Line SAE 30R7 20ft - High Pressure Fuel Line

In this review the EVIL ENERGY 3/8 fuel hose line is evaluated for anyone needing a durable replacement or new run of fuel line on automotive or equipment projects. The single biggest reason to buy is reliability: it meets SAE 30R7 construction and offers a 300psi working pressure with a 1200psi burst, so it suits typical fuel system, oil cooling, and steam emission uses where a robust, oil-resistant hose is required. The review focuses on build, compatibility, and practical fit for common installations.

Key Features

• ID and OD: The 3/8 in internal diameter and 0.63 in outer diameter provide a standard size that fits many fuel fittings and clamps without modification.
• Pressure ratings: A 300psi working pressure and 1200psi burst pressure give a wide safety margin for most vehicle and equipment fuel system applications.
• Temperature range: Rated from -40F to 257F, the hose performs across extreme cold and high-heat environments encountered under hoods and in open machinery.
• Material construction: NBR inner tube with braided polyester fiber reinforcement resists oil and wear, improving longevity where abrasion and chemical exposure occur.
• Media compatibility: Compatible with diesel, oil, gasoline, biodiesel and grease so it works across fuel system and lubrication lines without rapid softening.
• Bend radius: The 3.9 in minimum bend radius helps installers route the hose in confined spaces while avoiding kinks that reduce flow.

Who It's For

The hose is best for mechanics, hobbyists, and fleet maintainers who need a rugged SAE 30R7 compliant line for fuel delivery, oil cooling circuits, or steam emission venting. Its 3/8 in ID makes it a common replacement for small to mid-size engines and aftermarket fuel system projects.

Those who should look elsewhere include installers who need specialized PTFE or extremely high temperature silicone hoses for racing applications, or people needing very flexible low-pressure vacuum tubing; this product is designed around fuel resistance and pressure containment rather than ultra-flexibility.

Pros & Cons

Pros

• Durable NBR construction and polyester braid resist oil and abrasion for extended service life.
• Good value for money given the 300psi working pressure and 1200psi burst rating mentioned by users.
• Compatible with a wide range of fuels and lubricants, reducing the need for multiple hose types.

Cons

• Not as flexible as some silicone hoses, so tight routing may require larger bend radii or additional fittings.

Frequently Asked Questions

Can this hose be used with diesel and biodiesel?
Yes, the NBR inner tube is compatible with diesel and biodiesel as well as gasoline, oil, and grease.

Is this hose rated for high pressure fuel injection systems?
The hose has a 300psi working pressure, which suits many fuel delivery and return lines but not high-pressure direct injection fuel rails that require specialized high-pressure lines.

How flexible is the hose for tight installations?
It has a minimum bend radius of 3.9 in, so it is reasonably flexible but less so than silicone; plan routing to avoid sharp bends.
