Modern Vespa

Hi, in replacing the oil, air and fuel lines for my vespa LX 50 2T.

I'm just wondering what lines to use to fit and good quality to last long.

For the 2T, are these good

For fuel and air what size should I get and what's the best quality (I'd like transparent but I've heard bad things about them.

Thanks so much

They're cheap enough that if you want transparent lines, get transparent lines. They're not going to start leaking a week later.
What drives a lot of people nuts with transparent lines though is they will see things like air bubbles in the fuel line and think something's wrong. When you can't see it, the air bubble is still there, but it doesn't bother you. Air bubbles are normal in fuel lines.
