Tuel Tank Hoses
 

Hi Everyone,
So, over this summer my dad has tasked me to get his old 99 spec boxster race ready again. One of the items on the list was figuring out the weird issue with the fuel tank. When he last had it at a shop, this shop did something and removed the lines to the fuel filler vent/ bleeder valve and the charcoal canister. So I have two questions: 1. I know that the bleeder valve connects back to the fuel tank, but where does that hose come from on the fuel tank, and 2. The image below is of the top[ of the tank, right under the battery cover, what are those hoses and where do they lead to?
Thanks
