EVIL ENERGY Fuel Hose 1/2 in SAE 30R7 — 10 ft NBR Rubber, 300 PSI Working Pressure

EVIL ENERGY 1/2" Fuel Hose is a 10-foot, SAE 30R7 NBR rubber line rated for 300 PSI working pressure and built for diesel, gasoline, biodiesel and oil-handling applications.

This premium fuel hose combines an oil-resistant NBR (nitrile butadiene rubber) inner tube with a braided polyester reinforcement to meet SAE 30R7 performance. The hose is designed to withstand demanding fuel-system environments with a broad temperature range and a durable construction that resists wear, flexing and common hydrocarbons. It is supplied in a convenient 10-foot length for repairs, retrofits or custom installations.

How durable is this hose under pressure and heat?

The EVIL ENERGY hose handles a continuous working pressure of 300 PSI with a burst rating around 1200 PSI, providing a large safety margin for typical fuel-system uses. Its NBR compound resists oil swell and degradation while the braided polyester reinforcement improves tensile strength and abrasion resistance.

• Working pressure: 300 PSI; burst pressure: 1200 PSI.
• Temperature tolerance: from -40°F up to 257°F for cold starts and hotter engine compartments.
• Wall thickness: 3 mm for toughness and puncture resistance.
• Construction: NBR inner tube with braided polyester reinforcement for long service life.

What sizes and fittings does the hose support for installations?

This product is sized with a 1/2" (13 mm) inner diameter and 0.75" (19 mm) outer diameter, suitable for many common push-lock and crimp-style hose fittings. The 10-foot length gives flexibility to cut to size and attach compatible push-lock connectors or clamps for fuel systems, oil cooling loops, and other liquid transfer setups.

• Inner diameter (ID): 1/2" (13 mm); outer diameter (OD): 0.75" (19 mm).
• Minimum bend radius: 4.7" (120 mm) to avoid kinks and maintain flow.
• Length: 10 ft ready to trim for custom runs or replacements.
• Compatible with common push-lock fittings and SAE 30R7 installation methods.

Which fluids and systems is this hose compatible with?

The NBR inner tube is formulated for resistance to petroleum fuels and many lubricants, making it appropriate for diesel, gasoline, biodiesel blends, motor oil, grease and similar hydrocarbons. It is intended for use in fuel delivery lines, oil cooling circuits and other vehicle or industrial fluid pathways that call for SAE 30R7-rated hose.

• Compatible media: diesel, gasoline, biodiesel, lubrication oils, grease, and similar hydrocarbons.
• Meets and exceeds SAE 30R7 standards for fuel-handling applications.
• Not intended for compressed air or oxygen service—use only for rated liquids.

How do I install and maintain the hose to maximize lifespan?

Cut the hose square with a sharp blade and use appropriate push-lock or crimp fittings sized for 1/2" ID. Avoid sharp bends tighter than the 4.7" minimum radius and secure the hose to prevent chafing; inspect periodically for abrasion, cracking or hardening and replace if signs of wear appear.

• Trim with a clean, straight cut for reliable sealing with fittings.
• Maintain minimum bend radius of 4.7" to prevent flow restriction or kinks.
• Check clamps and fittings regularly for leaks and retighten as needed.
• Replace if the rubber shows cracking, severe swelling or other damage.

Who this is for: mechanics, DIY auto enthusiasts, fleet maintenance teams and fabricators who need a dependable fuel-line solution that balances pressure capacity, oil resistance and installation flexibility. EVIL ENERGY's 1/2" SAE 30R7 fuel hose is ideal for repairs, custom fuel-system runs and oil-cooling plumbing where a durable NBR-lined, braided hose is required. If your project calls for a 10-foot section of hose rated for hydrocarbons between -40°F and 257°F and capable of 300 PSI working pressure, this hose is engineered to meet those needs.
