by "design" the charcoal canister is only used to provide the gas tank a way to vent but to keep gas vapors to a minimal hence the charcoal whether or not it keeps the gas tank at a certain pressure I'm uncertain but i highly doubt it iv driven a few of my other cars without the canister for years and my fuel pumps never gave me any problems find a safe way to vent it outta the engine bay and id say you'd be all set or relocate it if you feel you have to keep it
same thing happens when you pump gas into your car or every time you take off your gas cap off just saying
It most certainly DOES keep pressure in the tank. The gas vapor is not simply dumped out of the canister or absorbed into the charcoal. Some might be, but the vapors are also pulled into your engine once the engine is at operating temp via the BVSV in the water neck.
Do you have any idea how fast gasoline evaporates? Sure, you lose a good amount of vapor when you take off the cap to refuel, but that's one release of pressure and vapor for a few minutes. Do you realize how minuscule that is compared to leaving it vented permanently? I refuel maybe once a week. I assume you're similar. Maybe even less.
That's roughly
3-5 minutes of venting gasoline vapors per week.
Now consider having it vented continuously. That's roughly
10,080 minutes per week.
So yeah, opening your gas tank cap to refuel is practically the same as leaving it open all the time. 4 minutes compared to 10,000 minutes. Pretty much the same. :nono:
NOT TO MENTION the fact that the gasoline (as like any other liquid I know of) evaporates at a slower rate when it has a confined, pressurized head space. Just because taking something off your car doesn't kill the car in a year doesn't mean you aren't causing undue damage...
