Where is the Evaporative Emission Charcoal Cannister on a Tundra?
My concern is that I'll inadvertently flood the cannister if I get too carried away with topping off my gas tank. On most vehicles I've had, the cannister is somewhere in the front part of the engine compartment and well above the gas tank. But I haven't yet found the cannister in the Tundra's engine compartment nor does it seem to be readily visible underneath.

if im not mistaken what your talking about can never be flooded with gas ,maybe with water its in your air cleaner above the filter. i might be wrong but i think if you examine the air filter you will find it there.

The EVAP Canister on the Tundra is mounted underneath on the opposite side of the driveshaft from the gas tank. It may be hard to pinpoint as there is a mounting bracket that almost totally obscures it.

Nope, thanks for the suggestion...but I just looked and that is very unlikely to be it. These charcoal cannisters have a vent tube coming up from the top of the fuel tank and another tube going into the vacuum side of the engine. The top of the air cleaner doesn't, for one thing, have any tube coming in from the gas tank. Seems to still be a mystery.

Thanks Glenn, appreciate the answer.
Doesn't sound like it's much above the tank so I'd better not over do my fillups.

i could be wrong, but i thought it was the black plastic plumbing etc. that's on the driver's side in the engine bay, near the main fuse box and the master cylinder.

That is where I thought it was also. I will have to check and see but I sure thought that was where it is. However, I have been wrong "one" other time.

Other than messing up the emissions, what are the implications of flooding the canister? I routinely add a gallon or so after the pump clicks off and so far there are no indications of any problems.

Well, messing up the emissions is one thing I definitely don't want to do. We have biennial emissions testing in my region and it can cost big bucks (and a lot of hassles) to bring a vehicle into compliance. I'm not sure that Toyota would cover repairs if the emissions failure cause was my overfilling the fuel tank.
Secondly, because engine vacuum is what purges those cannisters of fuel vapors, I'm not sure what would happen if the engine started sucking liquid gasoline into the intake system...but I have a gut feeling it wouldn't be a good thing to have happen.
It's encouraging to know you haven't had any noticeable ill effects from adding an extra gallon after first pump shutoff (and your Tundra is almost identical to mine)...that's also what I've been doing on the 4 tanks or so I've put into my almost new truck. But I got to wondering recently if that was a very wise thing to do. Although I'm not usually a Belt and Suspenders kind of guy, I'm thinking I'll err on the side of caution and not be doing that henceforth unless I know I'll need maximum fuel load for the next leg of a trip (there are still some areas of the Intermountain West where gas stations are very few and far between).

I'm not sure what year it changed, but the 2000 Tundras (both V6 and V8) have the EVAP charcoal cannister located on the driver's side front fender right in front of the brake booster and along side the brake master cylinder. It is shown on a couple of figures in section EC of the 2000 Toyota Tundra Repair Manual (Pub. No RM682U2) Vol. 2.

Alan - 2000 - 2002 in the engine compartment. 2003 and newer underneath.

its in your air cleaner 
above the filter. i might be wrong but i think if you examine the air filter you will find it there.
