Fuel Lines Help

Hi All,

I'm trying to change fuel lines on my 1970 Z.

The current markings are 1/4 ID Fuel-Vapor SAE 30R7 KVL

A couple of places I have tried today have every 30R other than "7" and of course 1/4 inch no longer exists.

Has anyone changed their lines from the US spec and if so, could you kindly tell me what new lines you used?

Thanks, Nick.

I'd go for a high number than 7. R8 or 9 would be more resistant to ethanol and keep the petrol smell down.
