i know of the airbox, 2 tubes for the clutch, but what else is there to snorkle?

if i have to snorkle all the hoses i see, can i just use the same material from an autoparts store and extend them?

on the pvc valve i found, can i just tap it onto a snorkle from the airbox?

please respond to any or all the questions here, and any other you would like if it would help, and thanks guys!
