What is This Hose and Valve For? Comes Out of Gas Tank

#1
Hello all,

I discovered a hose and valve that came out of the gas tank and weren't plugged into anything. I don't know what they are and don't know where they go. There's a slight chance that it is related to my P0440, P0441, and P0446 codes, but not necessarily. My pressure switching valve and fuel tank pressure sensor are already plugged in, so it shouldn't be either of those. I own a 2002 Toyota Corolla LE. Any help would be appreciated. Thanks!
