Replacing my petcock on my 1973 CB350

I'm a total beginner to bike repair. Does anyone know or have a video that shows how to replace my old petcock with a new one (which I have purchased)? I'm clueless how to drain the gas, remove the tank (if I need to), and install the new gizmo, but I want to use this as my first foray into leaning how to work on my bike rather than trying to find someone nearby who I need to pay an arm and leg to. Anything that really breaks it down and assumes no prior knowledge would be incredibly helpful.
Much obliged,

Welcome to the forum! You can drain the tank by closing the petcock - valve arm to stop - removing the fuel line from it and use another length of tubing that will allow you to dump into a fuel can. Open the petcock - valve arm to res - and it will drain the tank and reserve.

The petcock can be removed using an adjustable wrench on the nut - it has a right hand thread.
Thank you. For some reason I thought I had to take off the tank and remove both tubes as well as the tube that crosses over underneath. Much appreciated.
