Curious... what did you do in the end to fix it at 80k miles? Which VSV did you replace? Did you test the vacuum under the conditions stated in the FSM? What did it indicate?
I replaced the canister the unit includes the VSVs. Problem solved never ran into the issue again full tank wheeling at 12,000 feet. The canister it self was saturated.
New unit, which came with the VSVs. The canister was done, saturated and prematurely worn if you ask me. The VSVs we're working both one and the canister and at the engine I pressure tested both of them at 100 PSI and vaccum, triggered them on and off. Both opened closed and held pressure. I actually have a spare VSV from the engine I bought that first.
Your fix may have been the engine VSV, but that was not the case for me.

Toyota recalls over 2.98 million Toyota and Lexus cars to replace fuel tank charcoal canister
They need to get better at their canister designs.

That Prius recall wasn't a defective canister, it was the way it was mounted. The way it was mounted stressed the plastic over time, causing cracks. The canister worked fine, the fix was to install a strengthening bracket. The canister wasn't replaced or redesigned.
Hey, I igree that it sucks that the canister only lasted 80k miles for you. It could have been defective, sometimes they get killed by over filling. Every auto brand has canisters that wear out, and they don't usually go 200k miles. But at 80k miles, it was well out of warranty. The problem is it is actually a low demand part for a high end model that doesn't sell a lot of units, so low demand causes a high price for the part. You want a canister for an old Chevy 1500? Cheap. Land Cruiser? Not cheap. I'd bet most of the people on here that are having issues with their evap system have near a quarter million miles or over.
Sorry, I think you are missing my point. I wasn't in disagreement on your troubleshooting or successful end result. I was disagreeing with your statement of not reporting it and writing it off as wear and tear. My point in the link above is that Toyota acknowledged the danger of fire because of expelled fumes, that's exactly what happens to our trucks and inside the cabin. That needs to be reported and acknowledged by Toyota regardless of the age or warranty of the vehicle. In 2015 Chrysler recalled 1993 and up Jeep Cherokees for the placement of the gas tank and you know what it took? the death of a 23-year-old pregnant woman.
Perhaps Toyota should have put these somewhere where it's not directly inhaled into the cab? Or give the curtesy of an ECL when the VSC or canister fails? Or is the first notice to the driver that either needs to be replaced an explosion or a fire appropriate?
That's my point, this is something I think should be reported made a recall and addressed by Toyota.

I have 2004 with same issue. I will be building the heat shield this weekend. Thank you to everyone who contributed to this thread and Toyota should do a recall.
And is the heat shield still working for everyone? @1meancruiser

Built the shield.
I will post better pictures tomorrow.
Yes I built mine a year ago and have seen no issues since..
Thanks UZJ for posting pics, can you take one further away? I'd like to see where exactly you have it.
Wouldn't using heat shield/thermal wrap yield better results (and easier to install). Another area that maybe overlooked is the fuel return line from the fuel pressure regulator across the backside/top of the engine. The heat soak from that area contributes to heating the fuel.

the line going into the fuel filter from the firewall side is the feed/pressure side. The smaller line above the bracket is the return line, it is slightly smaller that the feed line on the late 100.
another way,, the damper gets the feed line and the regulator back end has the return line. (that you can't see going around the back of the intake)
the other way,,, pump, filter, damper, crossover over the intake, regulator, crossover the backside by firewall, down to near the CAT area.
I put a shield on there yesterday. We'll see. Replacing everything under the spare tire as the more money final fix. (2006)
