So I was working on my wiring in the hatch today, when I pulled off the passengers side panel to reveal a plastic container with a bunch of hoses on it. Is that a charcoal canister?... should it be inside the passenger compartment?

Also, it appears my awesome previous owner has replaced a wheel stud with a standard one some time ago... .really annoying cause there is only one nut that must go on that stud.... What is the proper standard size to replace this.

Thanks,

Adam

by the way its my 71 240z

tht's the fuel reservoir? i don't remember what it's called, lemme look it up. and yes it's supposed to be there

EDIT - evaporation canister

That's your evaporative fuel recovery system and if the tank is plastic, it's an early one. Later tanks were metal. Good link above.

Plastic evap tanks were used through at least 4/71 production, as I have a spare un-cracked one from my parts car, as well as the one still in my 10/70 yellow car. By 7/71 production they had changed to metal, as that's what's in my red car.

Thanks,

So just to get this right. That tank traps fumes allowing them to condense and go back into the tank?

... any decent tire store could get you into the right size stud and lug nut if the hole isn't too big now...

This is the intent. to keep the fumes from the environment. If you know about the dangers of gasoline vapors , I am with you about the surprise to find it in the cabin. My self I did away with the thing altogether. Gary

The wheel studs are M12 x 1.25 but I don't know the length.

Oh my, I'm shocked. You environmentally insensitive pig you...
