Tygon OEM F-4040-A Premium Cut Length Fuel Line 1/4" ID X 3/8" OD X 5' Feet

An excellent product for gasoline.

Seems to be real tygon. I always worry about knock-offs since they do not last and they will crack. Real tigon will last for years and they do in my 20 radio control airplanes.

Actually resists the gasoline in California. Its nice to still have flexible fuel line after eleven months.

Two month of racing and no issues. The line is still flexible, I can squeeze it by two fingers easily. Update: it isn't actually suitable for Rotax engines since the inner diameter is slightly larger which makes the engine starving in low speed high fuel consumption corners.

I used this Tygon F-4040-A fuel line to redo the fuel lines on both of my Yamaha XLT1200s, and it’s been a solid upgrade from the old, brittle hoses. It cuts clean, slides onto and fits the fittings well, and once clamped it seals up nicely without fighting it. The tubing is flexible without feeling flimsy, routes cleanly, and so far it’s holding up great with no leaks or weird softening. If you’re rebuilding/refreshing an older fuel system and want something that feels like the “right stuff” instead of generic hose, this has been worth it. Just make sure you measure your ID/OD before ordering so you get the correct size.
