Can the rubber line going from the carb to the charcoal canister be capped and removed without any problems? also can the line from the one side of the pvc vent to the charcoal canister be capped and removed?

Sorry about the probably stuiped questions, Its my first car and the hose from the carb to the canister tore, so I figured if I can get away with capping and getting rid of it would be better than replacing it with another ugly hose.

what kind of carb do you have? i have an edelbrock and i capped it on the carb and ripped the canister out it is useless emisions crap and the pcv valve you can get rid of and buy a breather for your valve cover

I would like to keep the PVC valve since from what I've heard it helps with crankcase pressure and I have the stock nonccc qjet. Im pretty sure Ill just cap it at the carb too, and leave the gastank lines there, im just not sure.

i left the lines too im just sayin you can get rid of the canister and ive have no problem with my crankcase pressure but anyways im not sure about the qjet carbs ive never had one but i would think they are similar enough that capping it would be fine

Just to be clear, Buy a vented gas cap, then cap every single other line that is going to the charcoal canister, and I should have no problems?

It's easier and cheaper to put an old fuel filter on the end of the fuel tank vapor line (so nothing gets sucked into it) than to get a vented gas cap. Easier because some people have a lot of trouble finding the appropriate part number for the cap.

Makes sense. Thanks... Just wondering but do you ever smell gas vapors?

Doing it the simple way, you have two choices. Either smell gas when you open the hood, or smell it at the back of the car. I did smell it a little. Then I figured out a solution, but it requires an extra thin hose:

Keep the small valve (looks like this http://www.rockauto.com/catalog/moreinfo.php?pk=39333 ) with one of the big connections on the gas vent line, the filter on the other big one, and on the small connection run a hose that goes to any vacuum source (I tee-ed it off the pcv line). When the engine is running, the valve opens letting your gas tank breathe in and not implode, and when parked, the valve is closed so no gas vapors get vented. Just make sure you use a real vacuum source that you can feel, some of the connections on the carb are just bowl vents and stuff.

Thats just one extra thin hose, much better than the ugly mess of huge hoses, that giant valve in front, and the temperature-controlled vacuum switches.

"I have the stock nonccc qjet"
Is raising a flag. The stock quadrajets were all the computer controlled kind. Except the canadian ones I think. Is that the case?

dirtrides2009, so how's your ride now w/out the factory emissions?

dirtrides2009

Its canadian. I can check the rpo tommorow though to confirm whether or not its ccc or not.

And I've been working the last two days so I havn't had time to pick up parts or vaccuum caps, but this week sometime for sure. Scooter, the only smog equipment left on mine is the canister, but it runs just fine and as strong as an LG4 can get.

That's cool. it took me forever to understand most of the smog stuff on mine and it really runs right for an lg4 too, but it's true, there's a lot of oem ugliness going on under my hood.

OP just out of curiosity is there a reason your removing the canister? I mean you said its your first car I don't think the first thing you should be doing is pulling off vacuum/emissions hoses. Its not like they are hurting anything. Just my $0.02....

dont be pulling no fricking charcol caniste roff!!!!!!!!!!!!!!!!! it wont effect your performance either way,if anythign you might screw up your tank venting and get a fuel starvation issue.

emission arent evil........i like to breath clean air like everyone else. im old enough to know cars from 60s and 70s with minimal emissions and the roadways stunk like gas all the time. the canister is helping to catch fuel vapors from your tank and carb when its not running,nothing more.it doesnt hurt performance.........period.

can you cap the big hose going from cabr to canister,why not,everyone whos replaced the q-jet had to do it. all that hose really does is let vapor go from fuel bowl to canister when its sitting. when you start it the engine sucks in air from the canister and captures some if not alll of that vapor stored in the canister. thats when your purge valve come sin. the one issue youll need to address is the tank venting.your fuel tank is vented via the canister, if you unhook it youl lhave an open vent line to the tank. do you cap it and cap your vent? then you can have a fuel starvation issue possibly. think of sucking on a straw with one end closed. eventually you colapse the straw and run out of rum/coke. some guys say put a small fuel filter on end of line and let it vent to the air... go ahead.. i wouldnt . theres also the issue of raw fuel escaping via the vent into an engine compartment. some say cap the line and by a vented cap????? show me a true vented cap ..ive never seen one in years. they stoppped making caps with holes in them for a reason. some say drill small holes in your current cap..i would but others do it. heavens forbid you roll it or have a crash allowing fuel to leak out them holes in your nicely drilled cap. ive seen human bodies burned and they look just like chicken legs when you burn the snot out of them on the grill.......

leave the canister on if you still have a qjet............

ok i wantted just to add something about the vent cap u r wrong...i have just bouth regular gas cap for my camaro cose it was missing on furst place...so the regular gas cap has a vent funktion...when u tight it up to klik 2-3 times then back it of till the point befour start unskrewing the cap that is a vent position...now some outher cars are diferent my wifes gmc start to unskrew right away....anyway

I have an 84 Z28 camaro first time owning one my canister isn't capped nor my carb. My carb is factory original I replaced bent fuel pump push rod but still not getting gas to carb. Wondered if it's due to canister or possibly my carb computer operated does have wires connected into the carb and on my car fax said there is a computer malfunction.

spicyskater

Canisters are known to start filling up the carb with charcoal wen they start braking down, I suggest u look in the fuel bowl. And u sed u had bend fuel pump pushrod this tells me someone ****ed up fuel pump installation,pull the fuel line out of the carb and observe if fuel is coming wile cranking.its possible for fuel pump cam lobe to go flat too...good luck
