Correct fuel injection size and place to buy

Time to replace my fuel injection lines. I see a lot of different sizes recommended, but would like one good answer. Size and place to buy would be very helpful.

I get my lines from NAPA.
Take one of the injectors along to try the fit.

A standard size.
Use fuel injection hose and - clamps. Cut all to length before installing. Depressurise the system first (disable the pump, crank). The line to the rail is larger than that to the injectors and you will have to look that size up, and there should be a list of all sizes somewhere.

I meant to say fuel injection hoses.
