Eunice 3/8" (10mm) Fuel Line Hose — 20 ft NBR Rubber, Oil-Resistant for Automotive (AN6/Push-Lock)

Eunice 3/8" (10mm) ID fuel line hose is a 20-foot, oil-resistant NBR rubber hose engineered to convey gasoline, diesel, biodiesel, engine oil or water for automotive and small-engine applications.

This heavy-duty fuel hose balances flexibility and chemical resistance for repair, retrofit or custom fuel-routing projects. Built with nitrile butadiene rubber (NBR), it tolerates common petroleum products and a wide temperature range, while its reinforced construction supports typical automotive working pressures. The hose is supplied in a continuous 20-foot length with 3/8 inch (10mm) inner diameter and a 5/8 inch (16mm) outer diameter, making it a fit for AN6-style push-lock fittings and standard barb clamps.

How durable is this hose under heat and pressure?

The Eunice NBR fuel hose is rated for a working pressure of 0.6 MPa (approximately 87 psi) and a burst pressure up to 1.8 MPa (about 261 psi), providing a safety margin for many automotive systems. Its NBR compound resists oil and fuel breakdown, and it maintains flexibility across a broad temperature window.

• Working pressure: 0.6 MPa (~87 psi)
• Burst pressure: 1.8 MPa (~261 psi)
• Temperature range: -40°F to 248°F (-40°C to 120°C)
• Material: oil-resistant nitrile butadiene rubber (NBR)

Will this hose fit my vehicle’s fuel fittings and layout?

This hose has a 3/8 inch (10mm) inner diameter and a 5/8 inch (16mm) outer diameter, compatible with AN6 push-lock fittings and most 3/8" barb connections when used with appropriate clamps. The 20-foot length gives installers plenty of routing options for engine bays, fuel tanks, or replacement runs without multiple couplers.

• Inner diameter: 3/8" (10mm) — common for AN6 systems
• Outer diameter: 5/8" (16mm) — fits standard push-lock housing
• Length: 20 feet — ample length for routing and custom installations
• Installation: use hose barbs and fuel line clamps or push-lock fittings

What fluids can I safely run through this hose?

Eunice designed this NBR hose to handle gasoline, diesel, biodiesel blends, engine oil and water, making it versatile for many automotive and small-engine tasks. Always confirm the fluid compatibility and system pressure of your application before fitting the hose to ensure safe, long-term service.

• Suitable: gasoline, diesel, biodiesel, engine oil, coolant/water
• Not for: strong acids, ketones, or chlorinated solvents without verification
• Tip: verify chemical compatibility and system pressure before installation
• Use clamps or push-lock fittings rated for fuel systems

Who is this for: The Eunice 3/8" ID fuel line is aimed at mechanics, hobbyists and fleet maintenance teams who need a reliable, oil-resistant replacement or custom fuel line. It’s a practical choice for classic car restorations, small engine repairs, race-prep plumbing (when pressures are within rating), or any project calling for a flexible, fuel-compatible hose in a 20-foot length. If your system demands higher continuous pressure or specific chemical compatibility, consult system specifications or choose a hose with the required certifications.
