What is the process of removing the black canister in the engine compartment, and what are the cons of this....?

thx in advance

 

No cons..it probably doesnt do its job anymore anyways.

The only downfall is the metal fuel line that will be exposed. It will vent fuel vapor into the engine bay. You can cut the line back near the tank and run a filter on it. Or leave it open. People say this is a hazard but mines like that...im to lazy to fix it right.

 

This is exactly what I plan on doing.

 

when i pull some of hte vacum lines off it idels higher is this bad??

 

the canister is there to filter fuel vapors before entering the atmosphere. if you dont live in an emissions state removing the canister is no big deal. just plug the lines that are attached to engine vacuum and you will be fine.

 

I didnt notice any metal line going to mine(86 iroc),maybe I missed it.The filter can be replaced but Im sure no one does it.If you have to pass a underhood visual inspection most inspectors will notice this missing.you could just set it there for inspection though.

 

sorry for the 2 post.you will have to plug any vacum line unhooked.this should correct the idle.

 

The canister also provides the vent to the gas tank. If you just plug the lines, the tank will either be under vacuum when drawing gas out, or under pressure when the gas heats up. Neither is a good situation.

If you leave the line from the tank open, you'll be putting gas vapors under the hood.

It's hardly a "no cons" thing to do.

 

i took mine out, sinc it uses copper fitting on the tb i solderd it closed, use a torch and some solder, fill the sucker right up, as for the line from the tank i put a little vaccum cap over it, the gas smell was just to much with it off.

 

And now your tank vents to...where??
You are surely asking for a problem without the vent...the pressure has to go somewhere when the fuel returns to the tank via the return line..and that isnt even talking about HOT days , and fuel expansion. I removed my cannister, but left the vent open.

 

Just do what I did. I'm running some vacuum tubing from that vent line into the front part of the fender. All fumes go out through there.

 

There is a little plastic valve for venting the tank, tucked up by the filler neck.

 

Why not just plug the metal line and run a vented gas cap like they did in the old days???

 

Since it doesn't seem to be much of an advance to remove it, why not just keep it there? THen you'll pass emission visuals, don't have to worry about (dangerous) fuel vapors in the engine bay, or not venting the tank at all.

As I see it, the best, and easiest, solution by far, would be just keeping it!

 

Because they dont make vented caps to fit our cars..

 

so by just leaving it open or routing it to vent outside the car waste any gas? or give worse milage? is this just an emmisions thing?

 

I think its both. Although I dont know what amount of gas you'll be wasting, i'd bet not very much. What get's me concerned, is the fire hazard. And little bit of gas isn't so little when your motorcycle burn right up, which my friends did. Nothing left of the engine than the block, only screws left of the carb.

In my opinion the canister system is a fairly good solution, quite similar to the expansion tank of the radiator.

 

its not an overflow tank....it vents fumes not gasoline!..the cannister filters the fumes....

 

If I remember right, it had two hoses connecting to it, didn't it? Wouldn't one of them be a return line?

 

no, as stated it just vents fumes, not actual gas. There is no return line.

 

Okey, my mistake then.
