Need to fix a fuel line?
These quick connector fittings are a simple solution.

You get a pair of them.

They're designed for fuel lines with an 11.8mm inner diameter, which is basically 3/8 of an inch or 10mm.
So they should fit a lot of common fuel hose sizes.

They're a quick-release type, which means you can pop them on and off without clamps or tools, making repairs or swaps a breeze.

They're made from nylon, so they're fuel-resistant and durable.

The colour is black.
They're universal, so they can be used on the left, right, or front of the vehicle wherever you need a fuel line connection.
The manufacturer part number is simply 'Nylon Fuel Line Quick Connect Release' – it's an unbranded part, but it comes with a 1-year warranty from the seller.
Made in China.

They're brand new, never used.
If you're doing a custom fuel system or just replacing a brittle old connector on a project car, these are a cheap and handy thing to have in the toolbox.
Just make sure your hose ID matches.

Simple, effective, and gets the job done.
