Help.... What are these parts?

[electrichombre]

Hey everyone. Been lurking for a bit after buying my 1LE. Going nuts over a P0442. I have thrown a new gas cap, purge solenoid, vent solenoid, new hoses, and all kinds of junk at it. I finally caved and had a shop hook up a smoke machine to it. Quite a loud hiss and fair amount of smoke on the front drivers side of the tank. Sadly, I'll have to drop the tank and inspect.

I've tried to search this without much luck. Can anyone tell me the part on the bottom right and the top three? I'm hoping it's a hose, but am also preparing to replace those if needed. Thanks for the help!

I think the bottom right is the fuel sending unit? If someone can confirm! I have been out of the game a while haha

our cars actually have 2 fuel level sensors since the fuel tank has 2 lower cavities to facilitate contour around the driveshaft. the part on lower right is second fuel level sensor. the parts on the upper area are evaporative emissions components. the leak could occur at any of these.

Thank you! Is there a diagram floating around showing what those are called? I am planning on just replacing all of them once I drop the tank.
