Pangda 1/4 in Fuel Line Hose — 20 ft NBR Return Hose for Small Engines, Low-Pressure Durable

Pangda 20ft Fuel Line Hose is a flexible NBR return-line hose with a 1/4" (6 mm) inner diameter designed for safe, long-lasting fuel return and supply on small engines.

This 20-foot (approx. 6 m) fuel hose from Pangda is made from nitrile-butadiene rubber (NBR) to handle typical fuel-return duties on small engines, hobby aircraft, motorcycles, boats, and many other fuel systems. Its compact inner diameter and robust construction make it useful where space is limited and reliable flow is required. The hose is intended for return or low-pressure fuel lines—double-check compatibility with your system's pressure and fittings before installation.

How durable is this fuel line hose under working conditions?

The Pangda fuel hose is manufactured from NBR rubber that resists fuel, oil and general wear. It’s built to operate through a wide temperature range and withstand routine pressures encountered in low-pressure fuel systems.

• Temperature range: -40°C to 120°C for year-round use.
• Working pressure: rated to 300 PSI for standard return-line applications.
• Burst pressure: tested to 1160 PSI, giving a safety margin under transient conditions.
• Construction resists cracking, fading and routine abrasion for extended service life.

What sizes and length does the Pangda hose come in, and will it fit my system?

This specific model is cut to about 20 ft (6 m) long with dimensions chosen for small-engine fuel return work. Check the inner and outer diameters to ensure a proper fit with your clamps and primer bulbs.

• Inner diameter: approx. 1/4 in / 6 mm, common for small-engine return lines.
• Outer diameter: approx. 0.47 in / 12 mm for clamp and connector selection.
• Length: approx. 20 ft / 6 m—enough for routing in many installations or trimming to size.
• Works well with primer bulbs and low-pressure fittings (primer bulb not included).

Where should (and shouldn’t) I use this Pangda fuel hose?

This hose is optimized for return oil/fuel lines and other low-pressure fuel circulation uses. It is not intended for high-pressure fuel injection lines or direct-feed injection systems—verify system pressure and application before using.

• Recommended for: return lines on model helicopters, motorcycles, boats, ATVs, generators and lawn equipment.
• Not suitable for: high-pressure engine fuel injection lines or systems that exceed the working pressure rating.
• Requires appropriate clamps and fittings; use a primer bulb where needed (not included).
• Inspect connections and routing regularly for chafe, kinks or heat exposure.

Who is this product for? The Pangda 20ft 1/4" Fuel Line Hose is aimed at hobbyists, small-engine mechanics and DIYers who need a cost-effective, flexible NBR hose for fuel return and low-pressure supply tasks. It’s especially useful when you need a long run to route fuel safely on motorcycles, boats, generators, small airplanes or custom fuel systems—provided you confirm system pressure compatibility. If you require a hose for high-pressure injection or a different inner diameter, choose a product rated specifically for those conditions.
