Thats a good question. I actually took mine off a while back, still have it in the garage somewhere.

I would try a place like Classic Industries or something. I'm sure they have some replacement parts like that.
I just checked and Classic Industries does have one. Its for a 1971-1977 Nova, for $92.99.

The other forum I'm on gets all riled up about posting links, so I'm not sure if its a big deal or not here. But if you go to Classic Industries you'll find it, or if you go to Google and type in Nova charcoal, you'll see it there too.

Looks like a nice brand new one too. Not cheap, but at least they still make these parts for us guys!

Thanks for the info. Rodney:)

Are you not running one at all..

Yes its in place,but i donot know what the condition of the charcoal in the canister is. Is it possible to just replace the old chacoal with something else? Can you even open the canister to repace it? On a budget like everyone Rodney
Correct, I'm not running one at all. My new gas tank just has a vented cap. My old tank ran a bunch of lines all over (EEC tank) and up to the charcoal canister. Since I ran the new tank, it just vents through the cap and I dont have to run any of that other stuff.

I believe there are two types of gas tanks for our cars, EEC and non-EEC. Can't remember what that stands for (emissions evaporation controls or something). One utilizes a vented cap, while the other is a sealed cap and vents to a metal box looking thing in the trunk under the package tray area and to the charcoal canister in the engine bay.
Why are you wanting to replace it? I believe all it does is collect fuel vapors from the gas tank. Yours might be ok as is. Though I'm not really sure how you check on them really.
Well if you dont need to have it on in your state take it off there should be a rubber hose half why down the car i seen a lot of people cut it at the hose and place a PVC valve on it soo the gas tank can still get air and no gas can come out of it. That sound like a great money saver...

Do you have a part number for the tank.. Im getting ready to buy a new one and i would rather go that rout and get rid of all them hoses.And when i get it you can put it in for me...Just kidding
That's true, different states have different rules. My car is an emissions nightmare, haha!

A lot of Novas didnt have the canisters though, many just had tanks with vented caps. I dont know how thorough some of these states are at checking to see if you have the original equipment on the car or not. Maybe you could just tell them you have a tank with a vented cap and thats how it came? Haha!
Haha sure man, just swing by and we'll toss in the new tank, haha!

To be honest I still have all the hoses that route up above the rear axle, there are metal lines and stuff that go through somewhere in the car. I never bothered to yank all that stuff out. Its mounted pretty solid in there. I just hacked off the rubber lines and took out the charcoal canister and called it a day.

The new tank is the same exact thing as the other one except it has a different sending unit. I believe the EEC tanks have three outlets on the sending unit whereas the non-EEC tank has just one outlet. Two were for vents and one for fuel I believe.

I ended up sumping my tank anyway, so I had to plug up the original sending unit line so fuel didnt leak out or anything. I wanted to still use my original fuel gauge so I left the rest of it in there.

I know some Novas had 5/16" fuel line while others had 3/8" fuel line. I think the bigger motors (350, 396, etc) came with the bigger line while the smaller motors (307, 250, etc) came with the 5/16" line. I yanked all that old stuff out too years ago and replaced it with all new 3/8" line since I was planning to drop in a bigger motor. The sending unit line was also 5/16", so I just sumped it instead of buying a new sending unit which was pretty expensive.

The tanks themselves are pretty easy to remove/install. The main thing is to remember to run it low on gas before you drop it, otherwise its a real pain. Dont ask me how I know that though, haha!

Yea im low on gas alright its emty..You going to woodward next week..
Not sure about Woodward, my wife is 6 months pregnant so I dont know if she'll want to sit in the hot car and breathe in fumes all day, haha! Might not go this year, maybe next year, we'll see though.

How about you?
Yea ill be there car wont be just finishing up front end still need to rebiult rear end and change gas tank out next month also cant what for harper cruise.
SORRY rrobin44 DIDNT MEAN TO HIJACK YOUR THREAD....
My car has a line running from the canister to the carb, can I just plug that if i want to remove it?
Cant remember what I did years ago when I unhooked mine. The only lines going to my carb now with it removed are the vacuum advance and the PCV hooked up to the valve cover.
