Eunice 5/8" (16mm) Fuel Line Hose — 10 ft NBR Rubber, Oil-Resistant Push-Lock for AN10/5/8" Barbs

Eunice 5/8" (16mm) ID fuel line hose is a 10-foot NBR rubber push-lock hose built for automotive fuel delivery and fluid lines that withstands oil, gasolina, diesel and temperatures from −40°F to 248°F.

This 10-foot Eunice fuel hose combines oil-resistant NBR construction with a push-lock friendly inside diameter to create a dependable, flexible line for cars, trucks, motorcycles and small engines. It’s engineered to meet working and burst pressures suitable for many non-pressurized and low-pressure fuel systems, and it’s sized to fit AN10 and common 5/8" barb fittings. The description below answers typical buyer questions and lists practical installation details to help you confirm fit and suitability.

Will this hose fit my vehicle’s fuel connections?

The hose has a 5/8" (16mm) inside diameter and an outside diameter of about 0.9" (23mm), making it compatible with AN10 and common 5/8" barbed fittings. Measure your existing hose inner diameter and the barb diameter to ensure proper fit before buying.

• Inner diameter: 5/8" (16mm)
• Outer diameter: ≈0.9" (23mm)
• Common pairing: AN10 and 5/8" hose barbs
• Length supplied: 10 ft (cut-to-length for custom runs)

How durable is the Eunice NBR rubber construction?

The hose uses nitrile butadiene rubber (NBR), chosen for its resistance to oils and petroleum-based fuels. It’s rated for typical engine bay temperatures and offers defined working and burst pressure values so you can match the hose to your system’s demands.

• Material: oil-resistant NBR rubber
• Working pressure: 0.6 MPa (≈87 psi)
• Burst pressure: 1.8 MPa (≈261 psi)
• Temperature range: −40°F to 248°F

What fluids and applications is this hose suitable for?

This Eunice hose is designed for conveying gasoline, diesel, biodiesel blends, engine oil and water in a wide range of vehicles and equipment. It is intended for fuel and low-pressure fluid lines; always verify your system’s pressure and chemical compatibility prior to installation.

• Compatible fluids: gasoline, diesel, biodiesel, engine oil, water
• Typical uses: fuel lines, transfer lines, small-engine plumbing
• Not intended for: high-pressure fuel injection systems
• Installation: use hose barbs and approved fuel line clamps

How do I install and maintain this fuel hose safely?

Installation is straightforward: cut to length, slide on a suitable hose clamp, push the hose fully onto the barb and tighten the clamp evenly. Routine checks for chafing, cracking or soft spots, and replacing clamps after prolonged use, will extend the hose life and help prevent leaks.

• Tools: sharp hose cutter, screwdriver or nut driver for clamps
• Fittings: compatible AN10/5/8" barbs and quality clamps
• Maintenance: inspect regularly for wear and replace if damaged
• Safety: ensure no fuel vapors build-up; work in a ventilated area

Who is this for: The Eunice 5/8" (16mm) ID fuel line hose suits DIY mechanics, automotive restorers, performance hobbyists and fleet technicians who need a flexible, oil-resistant 10-foot hose for fuel, oil or coolant routing in low- to moderate-pressure applications. If you require high-pressure fuel injection lines or FDA-grade coolant hose, consider a purpose-designed alternative; otherwise this NBR hose offers dependable service when matched to the listed pressure and temperature ranges.
