What is this? what should I do?

[bgsquad]

Guys, can you take a look at the picture and tell me what this "hose" or "tube" is? and is it dangerous to leave it damaged like that? i think it's only the tissue that is involved, but does it provide more reinforcement?

kindly advise, thanks.

i believe it's mainly for insulation - looks to be an A/C line - to reduce heat-pickup.

to be safe, maybe you can find some insulation wrap to wrap around there. others may know more here - haven't looked under the hood around this area yet.

looks like fuel supply pipe, have it inspected by professional as soon as possible .

Got mice?

yeah, looks like a rat or a mouse was shewing on it... but that's how it was when i bought it 6 months ago, and it still buggs me... waiting for my next dealer visit for check up, in around 3K miles... but i thought i would take your opinion on that... i don't want to pay $$$ to replace it if it's an AC pipe for example.. but if it's a brake pressure pipe, well, i should take it now...

Take it in just to be safe. Don't wait. There may be more damage that you can't see somewhere else. You could mention that made mice got a go at it, etc.

Is it leaking?hissing? have you checked when the engine is started?bloody rats for sure, alas they are everywhere, if it doesn’t leak, I am sure you can patch it up, so wouldn’t worry too much,especially if you have not noticed problems all this time

[bgsquad]

no leaking and no symptoms...
But i just wanted to know what is this pipe!

So? No one is sure what this pipe does?? where are all the "experts"?

That's an ac line. I wouldn't worry about it to much.

As stated previously, that is just heat shielding material around the metal piping.
