Missing a small hose and cant figure out what it is

if anybody had any idea what this hose is for that would be great thanks

Looks like a throttle body vacuum line to me

Do you know where this hose connects to and what the part name is called thanks

i followed mine around to the back of the intake manifold where is seems to run into the firewall on the passenger side. i assume it goes to the fuel tank but im not sure.
