The first picture is the carbon canister, i was going to remove this.. But i decided against it. Basically it lets the fumes vent properly from the fuel tank and fuel system.. If a spark appears in your engine bay, i.e king lead pops off and arcs out or literally anything, then bye bye to your bollocks lol! Remember fumes are more likely to catch alight!! So personally i'd leave it in there. The second picture is for aircon, that shit can be removed yeah. I did, and just cut the vacuum hoses short and shuved a bolt in the end. There are proper blanking caps you can get off ebay tho (socks has them on his). HTH.
