Those Who Removed Smog

When people remove the charcoal cannister/purge valve from their cars, many complain of their car/garage smelling like fuel. You definitely want the tank vented. The return-type efi system stirs up lots of vapors in the tank, and if the tank isn't vented properly significant vapor pressure can build in the tank. The fuel is flammable enough as it is - you don't want pressurized vapor in the tank to go along with it.
There's very little, if any, performance benefit to removing that part of the emissions system. Why not leave it on?

zero - re-read my post; that's my point. The liquid is flammable enough; pressurized vapor isn't just flammable - it's explosive.
As to whether you can pass emissions or not - it likely depends on how tough the visual inspection is, and how you vent the system. If you roll into the lab smelling of gasoline, you're gonna have problems.
For no gain, why bother removing the system?

i just relocted my charcoal canister to the inner fender, just get creative with the bracket and it will fit

Last night I stabbed the same guy 7 times in a row
For Example: When a Jet has to make an emergancy / crash landing the pilot dumps all the fuel and vapor out of the tanks when the plane is low on gas. The vapor is the most explosive part or gasoline....Or how about the smart people that catch their cars on fire while filling up the gas tanks? It all starts with a spark and vapor!
If your car is pretty stock, I'd leave the smog stuff. The smog is only an air pump and doesn't take to much HP from the motor.

Ive got sidepipes on my lowered truck, and I have always been worried everytime I start the truck after filling up. I wonder what the chances of it happening are.
I tore the ENTIRE car down and im replacing pretty much everything in the engine bay. If I was going to keep it, I would have to buy a whole new system just so that I didnt have to put my crap looking pump in with my new motor.

your talking about the air pump? that has to do with the cats i belive, i ditched my cats cause of no emmisions so i just deleted my smog pump too cause it serves no purpose without cats. as for the canister, like i said above, its not that hard to move it to the other side of the frame rail where it bolts, just bend the bracket abit and it will be outta site and still functional.

How about half of these cars have been hacked up already when bought, and that's usually one of the first things to get yanked by previous owners! (at least that's my excuse)

I actually mis-spoke; technically, gasoline in liquid form isn't flammable. Only the vapors are. If you can keep it from vaporizing, it won't burn at all. The Volvo charcoal cannister is already mounted up under the front fenderwell - completely out of sight unless you're under the car.

mine is siezed. the guy that I bought the car from just changed the belt around and its just sitting there doin nuthin. when I pull my engine im gonna take it off. I have two q's tho: what else can I pull besides the pump? And is it possible to use cats without an airpump?

as 88_GT_5_oh said, just relocate the canister.
as for emission test, do they do a visual or functional test or neither?? that depends on the state.
PS. the evap canister stores fuel vapor and releases it into the engine during cruise and other drive times thereby increasing fuel mileage slightly, and by not letting the vapor go to the atmosphere you get to use the fuel that you pay for.

I would definitely leave the canister in place with the lines and hoses to make it work. It is needed as part of the gas tank vent system. My 79 has it intact and working.
I had a Bronco with one missing, and it had a gas smell sometimes. My 82 had it missing, and I have spent quite a bit of time trying to get the gas tank to vent properly, and still be sealed in case of a rollover. I just put a stock car rollover valve in the unused return line. Still seems not to vent properly. Looks wise, you could just hide it.
