I have a 10mm and it isn't budging at all.

It's to the point where it's ruining the wrench... Anyone have tips on how to remove it? Tech?

 

Chainsaw and sledgehammer?

 

Is it a line wrench?
You may have to Gently use Vise Grips to get it loose.

 

What tech said... Flare wrench could possibly work as well... if you end up rounding the nut, you gotta use the visegrips ...

 

Small Propanetourch only way to go. i have done it in the past just blead the line a little and make sure it is noT clogged up after.Don't usemap gasway to hot.

 

^Would rather not use a torch, since there is too much flamable stuff there (brake fluid, PB blaster).

Tech, are vice grips pretty much the standard trick for you guys at the dealer?
I'm going to call around tomorrow and see if anyone has a tool to do the job...

You think Hammer + Flare wrench would work?

 

Hammer and a flare wrench should work, or vice grips. I've had success with both on some really bad brake and fuel lines.

 

Always if all else fails Vise Grips.
