EVIL ENERGY 5/16 Fuel Hose Line Push Lock NBR Rubber SAE 30R7 - 25ft

In this review the EVIL ENERGY 5/16 fuel hose is examined for mechanics, hobbyists, and small fleet owners who need a reliable replacement fuel line. The bottom line: this NBR rubber SAE 30R7 hose earns high marks for compatibility and durability, making it a practical choice when working pressure and chemical resistance matter. The reviewer found it especially useful where a semi-flexible, oil-resistant line is required, and the included measurements and pressure ratings remove guessing during installation.

Key Features

• ID and OD: The specified 5/16in ID and 9/16in OD provide a predictable fit for common push-lock fittings and most small engine nipples.
• Pressure rating: A 300psi working pressure and 1200psi burst pressure give a comfortable safety margin for many fuel system and oil cooling uses.
• Material construction: NBR tube with braided polyester fiber reinforcement makes the hose oil and wear resistant for longer service life.
• Temperature range: Rated from -40F to 257F, the hose can handle cold starts and high under-hood temperatures without immediate degradation.
• Medium compatibility: The NBR compound is compatible with diesel, gasoline, biodiesel and other oils, reducing the need for multiple hose types.
• Bend radius and flexibility: A minimum bend radius of 3.14in balances routing options with resistance to kinking on tighter runs.

Who It's For

This product is aimed at automotive DIYers, small engine technicians, and restoration hobbyists who need a straightforward, standards-compliant replacement hose for fuel delivery, oil cooling loops, or steam emission lines. Its SAE 30R7 construction and NBR material make it a good match where fuel compatibility and oil resistance are required.

Those who need extremely flexible tubing for very tight bends or specialized synthetic fuel compatibility should consider alternate materials; similarly, users requiring hose with integrated fittings or crimped ends will need to pair this hose with appropriate connectors and clamps rather than expecting factory terminations.

Pros & Cons

Pros

• High quality construction that customers noted holds up well with non-ethanol gasoline and typical diesel use.
• Workable flexibility and a 3.14in minimum bend radius that allows neat routing without kinking in most engine bays.
• Good value for a 25ft length at a practical pressure rating of 300psi for many applications.
• Durable NBR and braided polyester build resists oil and wear in under-hood conditions.

Cons

• The hose is semi-flexible rather than extremely soft, so very tight installations may require additional fittings or routing changes.
• No pre-attached fittings are provided, so buyers must provide clamps or push-lock fittings separately.

Our Verdict

The EVIL ENERGY 5/16 fuel hose is a practical, cost-effective choice for most fuel line and oil cooling needs where SAE 30R7 compatibility is required. It offers solid durability, a wide temperature range, and a safe working pressure for many automotive and small engine applications, making it a sensible buy for DIYers and professional users who will attach their own fittings.

Frequently Asked Questions

Can this hose be used with biodiesel?
Yes. The NBR compound is listed as compatible with biodiesel and typical petroleum fuels.

Does the hose come with fittings or clamps?
No. The product is supplied as a length of hose only; buyers should source push-lock fittings or clamps separately.

Is the hose flexible enough for tight engine bay routing?
It is semi-flexible with a minimum bend radius of 3.14in, so it handles most routes but may need extra fittings for very tight bends.
