Hi -- new to the forum and found you guys in my search for an answer to this question. I've read the background and done the homework, so I understand the basics. My 2004 Yukon suffered the same fate as many -- burst front line when going to stop while pulling up to the Arrivals at Newark Airport. not a happy moment! I know I need to replace all (they are just crumbling) and I know that you can find pre-bent kits including stainless ones (I saw somewhere that Summit Racing seems a good one but open to other suggestions). but here's my real question -- my dealer first gave me a phone quote of 1500-2000, which sounded real high, then when I pressed them that I heard about the GM kits being available to save on labor, she came down to 1000 or maybe a little less. (yes I know thats not comforting). my question is, how hard is this to do yourself? Esp without a lift? I'm real handy having just replaced the fuel pump on the same vehicle after those lines rusted through so I'm not a newbie. but can the pre-bent lines be snaked in w/o living the engine or taking too much out? anyone done this themselves? I've looked for videos but to no avail. thanks! john
