dojobkinb 3/8" (10mm) NBR Fuel Line Hose 20ft — 300 PSI Working Pressure, Fuel-Compatible

This heavy-duty NBR (nitrile rubber) fuel line is built to deliver reliable fluid transfer for automotive and engine applications. The hose combines a 3/8" (10mm) inner diameter with a 2/3" (17mm) outer diameter and comes in a convenient 20-foot length. It’s formulated to resist oil, gasoline, diesel, biodiesel and many common automotive fluids while handling a wide temperature range and elevated pressures suitable for fuel systems and related tasks.

How tough is this hose for everyday garage or workshop use?

The NBR construction emphasizes wear resistance and heat tolerance, so the hose stands up to frequent handling, bends and contact with hydrocarbon-based fluids. It’s rated to operate from -40°F to 257°F, so it performs across cold startups and hot engine environments without rapid degradation.

• Premium NBR rubber resists abrasion and swelling from fuels
• Operating temperature: -40°F to 257°F for broad climate use
• Good chemical compatibility with gasoline, diesel, biodiesel, oil and grease

Will this fuel line handle my engine’s pressure requirements?

The hose carries a working pressure of 300 PSI and a burst pressure of 1160 PSI, giving a wide safety margin for many automotive fuel delivery and accessory circuits. Always verify system pressure for specific applications and install using correct clamps and fittings to maintain safety and leak-free service.

• Working pressure: 300 PSI suitable for many fuel system tasks
• Burst pressure: 1160 PSI provides built-in safety margin
• Use proper push-lock fittings and clamps rated for the hose size

What sizes and compatibility should I check before buying?

This hose has a 3/8" (10mm) inner diameter and a 2/3" (17mm) outer diameter, supplied as a single 20ft spool for cutting to length. It is compatible with fuels and common automotive fluids but not all chemicals; inspect compatibility and pressure needs before integrating into any system.

• Inner diameter: 3/8" (10mm) — matches standard push-lock fittings
• Outer diameter: 2/3" (17mm) for clamp and routing planning
• Length: 20ft roll — cut to desired runs and assemblies

Who is this for? This Dojobkinb 3/8" NBR fuel line suits mechanics, hobbyists, restoration specialists and DIYers who need a resilient, fuel-compatible hose for automotive engines, fuel tanks, pumps, oil coolers and similar systems. It’s intended for non-corrosive hydrocarbon fluids and general-purpose automotive use; for specialty chemicals, very high temperatures, or OEM-mandated hose types, confirm compatibility and certification before installation. Install correctly with rated clamps and fittings, route away from sharp edges and heat sources, and inspect regularly for wear or leaks.
