Pangda 20 ft Fuel Line Hose 3/8 in NBR Return-Line for Small Engines, 300 PSI

Pangda's 20 ft 3/8" fuel line hose is a nitrile rubber (NBR) fuel-supply tube designed for return lines on small engines, offering durable, temperature-resistant fuel transfer when paired with appropriate fittings.

This single-piece fuel hose from Pangda is built for replacement and repair on a variety of fuel systems where return-line tubing is required. It's engineered with a 3/8 inch (≈10 mm) inner bore and roughly 17 mm outer diameter, supplied as a 20-foot (≈6 m) coil so you can cut to fit. The NBR compound balances fuel resistance and flexibility for routine service environments; use it only on compatible low-pressure return circuits and with external primer bulbs or clamps as needed.

What are the exact dimensions and pressure ratings of this hose?

The hose measures about 3/8" (10 mm) inside and approximately 2/3" (17 mm) outside, with a total supplied length close to 20 ft (6 m). It is rated for a working pressure around 300 PSI and has a burst pressure near 1,160 PSI—suitable for many return-line applications but not for fuel injection systems.

• Inner diameter: ~3/8 inch / 10 mm
• Outer diameter: ~2/3 inch / 17 mm
• Length: ~20 ft / 6 m (single piece)
• Working pressure: ~300 PSI; burst: ~1,160 PSI

Which materials and operating temperatures can I expect from this tubing?

The Pangda hose is manufactured from NBR (nitrile butadiene rubber), a common fuel-resistant elastomer for fuel and oil exposure. It remains usable across a wide thermal span, giving flexibility in cold starts and elevated-heat conditions, but always confirm system compatibility before installation.

• Material: NBR rubber for fuel resistance and durability
• Operating temperature range: -40°C to 120°C
• Good abrasion resistance for routine mechanical handling

Can this fuel hose be used on my vehicle or equipment?

This hose is suitable for return fuel lines on many small engines and fuel systems—examples include RC helicopters, motorcycles, boats, lawn equipment, and diesel truck return circuits. It must not be used for high-pressure fuel injection lines; check your system's pressure and the recommended line type before replacing hoses.

• Recommended for: return oil/fuel lines on small engines and auxiliary systems
• Not for: engine fuel-injection systems or other high-pressure feed lines
• Requires: appropriate fittings, clamps, and external primer bulb when needed (not included)

How should I install and maintain this Pangda fuel line?

Cut the hose to the needed length and secure it with compatible clamps or barbed fittings to prevent leaks. Inspect for cracking, swelling, or hardening over time—replace when deterioration appears. Keep fuel-contact seals clean and avoid long-term exposure to strong solvents beyond normal fuel contact.

• Use proper clamps or barbed connectors for leak-free joins
• Replace if rubber shows wear, stiffening, or soft spots
• Store coil away from direct sunlight and high heat when not installed

Who is this for: The Pangda 20 ft 3/8" fuel line is intended for hobbyists, mechanics, boaters, and fleet or equipment owners who need a long, flexible replacement hose for return fuel systems on small engines. It suits anyone needing durable, fuel-resistant tubing with broad temperature tolerance—provided the system operates within the hose's pressure and application limits.
