EVIL ENERGY 3/8" NBR Fuel Hose 10ft – SAE 30R7 300 PSI Oil-Resistant Braided Fuel Line

This heavy-duty fuel hose from EVIL ENERGY is built for vehicles and equipment that need a reliable, oil-resistant line compatible with gasoline, diesel, biodiesel and other common fuels. Constructed of nitrile butadiene rubber (NBR) with braided polyester reinforcement, the hose combines flexibility with strength for fuel-system use, oil cooling circuits, and general fluid transfer. Its temperature and pressure ratings make it suitable for a wide range of operating environments without sacrificing durability.

How strong and flexible is this 3/8" fuel hose?

The EVIL ENERGY line balances durability and pliability: a 3mm wall over a 3/8" (9.5mm) inner diameter provides structural integrity while maintaining workable bend radius. The braided polyester reinforcement boosts burst resistance so the hose can tolerate pressure spikes and repeated flexing.

• Inner diameter: 3/8" (9.5 mm)
• Outer diameter: 2/3" (17 mm)
• Wall thickness: 3 mm
• Minimum bend radius: 3.9" (100 mm)

What pressures and temperatures can it handle?

Designed to meet SAE 30R7 standards, the hose has a working pressure of 300 PSI and a safety-oriented burst pressure of 1,200 PSI. It is rated for a broad temperature window so it remains operational in both cold starts and high-heat conditions typical of engine bays and equipment rooms.

• Working pressure: 300 PSI
• Burst pressure: 1,200 PSI
• Temperature range: -40°F to 257°F (-40°C to 125°C)

Which fluids and applications is it compatible with?

The NBR compound formulation used by EVIL ENERGY gives the hose strong resistance to petroleum-based products and many lubricants. That makes it suitable for fuel delivery, return lines, oil cooling, and other systems that carry diesel, gasoline, biodiesel blends, oil and grease. Avoid uses with fluids incompatible with nitrile-based materials (check chemical compatibility for specialty fluids).

• Compatible mediums: gasoline, diesel, biodiesel, oil, grease
• Common uses: fuel systems, fuel return lines, oil coolers, equipment fluid transfer
• Standard: meets/exceeds SAE 30R7 performance

How do I install and maintain the hose for long life?

Install using appropriately sized push-lock fittings or clamps rated for fuel service, and avoid sharp bends near fittings to prevent stress points. Periodically inspect for abrasion, hardening, or leaks; replace if any degradation appears. Proper routing away from extreme heat sources and moving parts extends service life.

• Use fuel-rated clamps or push-lock fittings
• Maintain minimum 3.9" bend radius at installation
• Inspect regularly for wear, cracks, or leaks

Who this hose is for: EVIL ENERGY's 3/8" SAE 30R7 fuel hose is intended for mechanics, fleet operators, DIY automotive enthusiasts and equipment technicians who need a resilient, oil-resistant fuel line for fuel delivery and oil-cooling systems. If you require a flexible, reinforced hose that handles common fuels and lubricant exposure under a wide temperature range and up to 300 PSI working pressure, this 10-foot NBR hose is engineered to meet those needs.
