Here's the AC Delco installed.

Now, the plumbing....
This pic from the 2001 FSM is helpful to know how the OEM system works and which lines to connect to the AC Delco.

The Air Inlet line is the one we delete with the 3 terminal AC Delco Canister. Everything else is the same...
OEM Purge Line goes to the AC Delco Purge Tube
OEM EVAP Line goes to the AC Delco Tank Tube (I moved this line to the top of the filler tube vent line on my setup with the aux tank)
OEM Air Drain Hose goes to the AC Delco Air Tube (Fresh Air Inlet). Remember the OEM has a separate in and an out here. The in comes from the intake plenum (filtered) and the out goes down into the drivers side frame rail under the battery. Don't connect the AC Delco Air Tube to your Intake Plenum...you don't want gas and fumes mixing in with the intake air, uncontrolled.

I plugged the hole in the intake plenum with a rubber brake bleeder zerk cover:

Here is the intakel line removed that ran across the top of the air manifold at the back:

Just ordered the GM vapor canister on amazon. Gonna try running it in my 02 LX470 to see if it eliminates pressurizing of the fuel tank (noticed when unscrewing gas cap).

That should be interesting.
Keep in mind, some fuel tank pressure is normal! (see: owners manual)
 
I've been running the Tundra 4.7 charcoal canister (77740-34080) that @89BIGBLUE recommended for probably six months now. It's been trouble free and is nearly identical to the factory LC canister. I don't remember what I paid for it, but I think it was half the cost of a new LC canister, but I wasn't even able to source one in the US, so this is the next best option. My original lasted over 250K miles, so I'm hopeful that this one will last just as long.
 
I also forgot to add that right after I installed the new charcoal canister, we drove our 100 from Denver to Baja and back, 3,000 miles. No problems, even with unknown fuel quality down in Mexico.

Installed a new Tundra unit (77740-34080) to replace my 2000LC unit (77740-60390). Original was still seemed to be working correctly on my last trip where I did have some fuel boil, and I just wanted to get a new unit in there. I did find that one vacuum hose on the new unit was not long enough to connect to the VSV I swapped over so I reused the old one.

I also was able to weigh the new vs old units with the old one weighing about a pound more.

Old unit is free to anyone that wants it, otherwise it will end up in the trash.
 
Anecdotal AF:

about 18 months ago, I started filling my tank with mid tear gas exclusively. Since then, my charcoal filter has functioned as intended.

Sweet Jesus, there is a Chevron refinery and harbor about 30 miles from that California station. There is no refinery on the island of Kauai. I dream of adding a transfer case between my rear differential and drive shaft, then bolting an electric motor to the redundant front wheel drive output, making my 100 a golf yacht. I am sure there are 1000 reasons why it would never work, but there were 1000 reasons an LS in a Miata would never work. I am thinking short 3 mile round trip type of uses. The ultimate mall crawler mod.

I finally dug into the canister project after having a donor canister gifted to me by #awesomeissquid. Thanks for the incentive!
The road trip last year put me on the path of finding out why with an ambient temp greater than 94 degrees (F), the fuel tank would pressurize and the fuel vapor would fill the engine compartment.
So with awesomeissquid's canister on the bench, the cutting began. First with a hacksaw blade, then a razor knife, and after no real success I went with a power sander/cutter with a half round blade.




Cut right along the bottom seam and found success. And when it's time for it to come off, look out with the spring pressure.



Carefully emptied out the charcoal and weighed it separately...... BUT, forgot to calculate in the added weight of all the fuel vapors, and how much charcoal can actually hold.



Thinking I needed that much weight of charcoal, I ordered two containers from Amazon along with the JB Weld plastic bonder.
The one 40 ounce container was more than enough to refill the cannister.


I also soaked and cleaned the filter pads of the cannister in Simple Green and rinsed them with water, then dried them for two days while waiting on the charcoal.


Came up with an idea of holding the cannister upright, so I made a vertical vise option on my vise stand for the epoxy to set and cure for 24 hours.
Laid a bead of epoxy around the body, then place the bottom on it with fitting the springs in there, squeezed it togather and let it set.



A day later, I went back and put another coating of epoxy around the seam to fill in any gaps.




With the donor cannister done, I replaced the original and weighed them while they were both out on the bench. Fresh charcoal is about a pound lighter.



Installed, one drive cycle down and no CEL or codes so far. Going to start really checking the mileage now and hope it improves with this "upgrade".
 
Nice thread. Good to see some folks rebuilding these canisters.

If anyone has a used charcoal canister from an 05-07 (p/n# 7740-60450) and doesn't need it, let me know. I've rebuilt a few off other vehicles and wanted to dig into one of these. @Tummler or anyone else that has replaced theirs recently.


 
Yes!
The 77740-34080 I put in has been running great as well.
No issues to report.
It’s about to get hot out here in the Southwest, and I’ve got adventures at altitude planned. I’ll let you guys know if anything comes up, but confidence is high.
... and me as well.
 
Damn! The 00-02 tundra canister is no longer on sale 77740-34080 does anyone know of any alternatives? Not on amayama, partsouq, dealers around here and impex! Plz halp
 
Alright everyone Amazon still has them, very strange and it’s shipped and sold by Amazon so it seems legit. I ordered 358$ it pains me but I feel like it’s worth it. Will update. If anyone has Jerry rigged any other canisters or found one that’s close from other vehicles it would give new life to these old cars.
 
Do the overseas models have the evap/smog equipment?

Looks like the 2UZ equipped 100 has a very basic charcoal canister overseas, for a 100 with or without a sub tank. This part is NLA.
