Pangda 20 ft Fuel Line Hose 3/8 in — NBR Oil-Resistant Tubing for Small Engines, Low-Pressure Return Lines

Pangda 20 ft fuel line hose is a 3/8-inch (≈10 mm ID) NBR rubber tube engineered for fuel return and low-pressure supply lines in small engines and equipment.

This flexible fuel hose delivers a long, heat- and oil-resistant run for repairs, replacements, or custom routing on motorcycles, lawn equipment, marine outboards, small trucks and hobby helicopters. Built from nitrile butadiene rubber (NBR), the tubing balances fuel resistance and flexibility so it withstands vibration and bending while staying reliable under typical return-line conditions. Read the specifications and application notes below to confirm compatibility before installation.

What sizes and physical specs does this hose offer?

The hose measures approximately 20 feet (about 6 meters) in length with a 3/8-inch (≈10 mm) inner diameter and roughly 2/3-inch (≈17 mm) outer diameter. These dimensions suit common carburetor and return-line fittings used on many small engines and accessories. The long length gives you enough material to route around frames, tanks, and engine bays without seams.

• Length: ~20 ft / 6 m
• Inner diameter: ≈3/8 inch / 10 mm
• Outer diameter: ≈2/3 inch / 17 mm
• Single-piece package: 1 hose

How durable is the material and what temperatures/pressures can it handle?

The tubing is manufactured from NBR (nitrile butadiene rubber), chosen for its resistance to petroleum-based fluids and abrasion. It operates across a wide temperature range and supports typical return-line pressures, though it’s not intended for high-pressure fuel injection systems.

• Temperature range: −40°C to 120°C
• Working pressure: 300 PSI
• Burst pressure: 1160 PSI
• Construction: oil-resistant NBR with quality workmanship

Which vehicles and systems is this hose suitable for?

This hose is intended primarily for fuel return circuits and low-pressure supply lines across a variety of small engine applications. It works well for motorcycles, scooters, lawn mowers, generators, small boats, model helicopters and many light-duty trucks when used as a return or vent hose rather than a high-pressure feed line.

• Common uses: fuel return, vent, and low-pressure fuel lines
• Compatible platforms: motorcycles, marine outboards, lawn & garden equipment, small trucks, hobby aircraft
• Not for: high-pressure fuel injection ports or fuel pumps that exceed specified working pressure

What installation and safety points should I be aware of?

Before installing, verify your system’s operating pressure and confirm that return-line routing is acceptable for this tubing size. The hose is flexible but should be cut cleanly and secured with appropriate clamps; a primer bulb for fuel transfer is required when used in some setups and is not included. Always inspect hose ends and clamps periodically for wear or leaks.

• Check system pressure compatibility before purchase
• Use suitable clamps and a clean, straight cut for fittings
• Requires a primer bulb in some installations (not included)
• Periodic inspection recommended for wear and leaks

Who is this for? If you maintain motorcycles, small marine engines, lawn and garden equipment, generators, or hobby aircraft and need a durable, oil-resistant return or low-pressure fuel line, this 20 ft Pangda NBR hose is a practical choice. It’s best for DIY mechanics, repair shops, and builders who need flexible, long-length tubing for routing fuel return or vent lines—but avoid using it where manufacturer instructions demand high-pressure injection-rated hoses.
