So on occasion, which seems to be on warm or hot days, the CEL pops on and I get these codes:
P0446
P0442
P0441

So there's an issue with the evap/vac lines some where... Again, Not messing around I plan on changing/replacing all those rubber hoses on the driver's side behind the battery & fuse/relay box.
Anyway, I can't see to find the parts schematic with all the part numbers so I can order all these components.
I tried doing a simple search on RockAuto & AutoZone... can't seem to find any shaped/formed hoses.

Yes, I tried searching... all I found was empty comments and no part numbers... NO I don't want generic stuff... I want the preformed/shaped hoses and that box-module "thingy" too.

Since this line is dry-rotted, I'm thinking it's the one causing me these codes [P0446/P0442/P0441].
Two pics directly below... different views... Plus, Happy Father's Day everyone!

But I replaced the evap-canister over the fuel tank back in 2018 with a Dorman version.

P0441 doc:
I have replaced the "purge-valve" with an OE one back in 19/20... see page DI-157 step-6 "Check Purge Valve"
Page DI-158, "Check VSV for CCV"... I was trying to find the part number for "VSV" part. What does these abbreviations stand for? I didn't see any description...
-
I figured I'd start with the dry-rotted hose but since I gotta mess with those other hoses... just do the job "up-front" one time.
Really don't want to deal with that canister again... =)
That Dorman canister was still pricy and the OE one was another $100 more.
-
Plus, I had to go back to the OE gas cap since the "key-lock" cap some how created tank pressure... always had a "hissing" sound when I start opening this cap to fuel-up... so I had to slowing release this residue pressure before simply "pulling/twisting-off" the locking cap.

I did another search this morning & stumbled in this:



But I can't seem to relate this schematic to my truck [via my truck pics].

I clicked "2.4L 2wd" but the pic/schematic looks like the v6 version versus the 4cyl one...

What do you think?

Plus I couldn't find a phone # to call a reputable dealer that would help us forum members here... any suggestions?
I'm thinking I may have to call a parts department dealer to get help...

Hey...
I was on vacation, at first glance, yes, this appears to have the part numbers I'm looking for.
So I used your link & ended-up calling YotaShop in Washington State.

Very knowledgeable & this is the diagram for my 2.4L based on VIN... So I'm posting up as future reference for other Tacoma owners.
Of course, toyota prices are... "pricy"... which I have no choice due to the truck's age.
Hopefully, I won't have to replace the DORMAN EVAP canister over the fuel-tank... again... and I solve my evap/CEL issue!
