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

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.

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.

These may not be the best for my needs but they seem like good quality. They are very flexible which some may regard as a benefit, in my case, it made for a loose fitting that a clamp would not help. The company offered to send me a size lower which I installed the other day. It was a very very tight fit but they seem to work without any noticeable power loss. For a metric bike, you'll have to order a size lower than you might think but they'll work.

appreciate that it was exactly what it was advertised to be, most likely real tygon tubing

Genuine Tygon line, super stretchy, holds it's shape in tight bends much better than other fuel lines and doesn't kink and restrict flow. Grabs onto fuel filter barbs and doesn't let go, seals great too. Best fuel line you can buy for any gravity fed carbureted engine hands down.

Nice flexible fuel line!

Worked perfectly

An excellent product for gasoline.

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.

Good stuff. I bought some other similar fuel line, but was shocked at how unbelievably brittle it was.. would turn solid as a rock as soon as fuel was run through it.. you could get the fuel line on, but could never get it off without breaking it. This stuff though is great. Have reconnected several times, and trusted it to replace all existing 40 year old fuel lines.

Proper tygon fuel line. Stays soft for no leaks

Wish a 6ft option was available, there was not even half an inch left over after changing all the lines on my 488 supersport. Seals great even without clamps, no leaks!
