Vacuum lines, fuel pressure regulator line

Hey guys and gals, first time on a forum of any type, looking for some help identifying size and type of tubing for all my vacuum lines, and then the line that connects my fuel pressure regulator to the metal line…autozone and oreilly have all these different types of hoses but I can’t seem to find vacuum line and fuel line sizes and types. 2000 Tacoma 2.4 2wd. Located in the desert SW, would like to try silicone tubes maybe? Any help is appreciated.

 

You may have to remove an easy one in the store parking lot for this one or measure it with a caliper. Those hoses are sized by inside diameter
