“I used this repair kit on my 2011 HHR a few weeks ago and it is fabulous! It resolved a number of issues, obviously and primarily the fuel leak. Note, there is not a requirement to remove the old corroded lines - you can use them to tie the new nylon lines to. I liked this kit/solution because it was very easy to work with, and is better than replacing the entire line with a steel/OEM one - over time, those will corrode and deteriorate the same since the design issue still exists. The nylon tubing will not corrode.
Remember, you are saving a ton of money over taking your vehicle to Chevrolet or a local garage, so don't be cheap about getting the right tools/accessories to do the job right. Spend the couple dollars to purchase the tool for removing the existing lines from the quick connects, it will make the repair a lot easier (there's a reason they are named "quick connects" and not "quick disconnects"). Purchase a mini pipe/tube cutter - buy the $15 one that is great over the $10 one that is difficult to work with. As at least one review mentioned - buy heat shield wrap before doing the repair...again, another $15 will not budge the needle on the total repair cost compared to Chevrolet doing it.
This is a low cost, high quality solution. Inline customer service was also very fast and responsive when a problem with my order arose.”
