My daughter's 2011 Gen III had the check engine light come on,and no fiddling with the gas cap helped. The dealer ran a smoke test, and it revealed a small rock nick in the evap line coming off the top off the gas tank. This line only comes with the tank, at $500. Toyota thought to protect the fill hose to the tank,but didn't seem too worried about any of the hoses associated with the evaporative emissions system. With labor,the bill was about $800. No warranty of course. I know a little dab of silicone would have fixed it,but the dealer said that couldn't fix it that way. Her insurance should cover this under a comp claim,still waiting to hear back. Anyway,I just bought a length of 3/4" pipe insulation,and wrapped all of this tubing on my 2012. Of course we will do her car next,and then I'll do my dad's 2010. Remember Murphy's Law,this is a 20 minute fix,don't wait !!! BTW,just in case you were wondering, the tank is coated inside.
What a bummer !! I think I can understand why the dealer could not repair this hole being that it is part of the evaporative emission systems. I would have told the dealer that I would repair it myself and then patched it when I got home. Thanks for the heads-up !!

That's exactly what I told my daughter i would have done. They could have made up something to get paid for the trouble shooting,we did it all the time back when i worked at a Ford dealership. We are saving the old tank of course, remember the "pin hole" post of a few days ago.With 3 Prii in the family, we may need it!!
Whicks, is that a picture of the hose wrapped with your 3/4 pipe insulation or is that what the stock hose looks like, (before its wrapped). The first picture looks like your possibly holding the damaged end (damage about 3 ribs down from the top). Thanks!
The wrapped pipe in the photo is the fuel fill tube. The smaller flexible tube is the damaged one. there are quite a few tubes in this system once you get under the car. I wrapped them all while I was under there. Since this is a sealed system, a hole in any one of them should cause the check engine light to come on. My next project is to design a skid plate for the gas tank. Plastics are a great weight saver, good at fending off sharp objects,not so much!!!
OK - I am curious about the photos... What is the large hole on the top of the tank for? It looks like it is about 4-5" in diameter?
That is indeed where the fuel pump assembly attaches. There is a locking ring and seal of course. Quite a large hole compared to some others I've seen.
When I read your post the first thing I thought of was duct tape. I noticed the link that recommended duct tape. That would have fixed it for a lot less.
I haven't been able to find out what the liner is made of,of course it's a given that it's flexible enough not to pop off,and let's hope it lasts forever.As a motorcyclist, I'm all too familiar with tank coatings that failed ,let's all hope Toyota got this one right!!!
Whicks3, Can you post a picture/description of where to find this hose underneath the car? Just purchased at 2012 Prius. Chris
Saab had this great idea to route the fuel filler pipe through the wheel well. So if you cut a tire or picked up some road debris you could split that tube. My wife absolutely shredded a tire and tore the pipe all to hell. So after replacing a wheel and tire, I got a thrilling gush of gasoline at the next fill up! Junkyard reduced my total repair bill to $250(incl wheel)...Saab wanted $425 for the filler tube, $80 for the rubber bushing (tubing) to attach to the tank, $500 for the wheel. Hope the OP kept the tank, likely has some value on ebay!
