    • Nice
Nice little kit pretty expensive though for what you get but it works well hard to get in tight spaces

    • My Buick was leaking gasoline onto the engine. It's a wonder the car didn't go up in flames.
My Buick was leaking gasoline onto the engine. It's a wonder the car didn't go up in flames. I took it to a local shop because he said he could fix the fuel line. If he had made the new line up according to the directions which come inside the kit, it probably would have been okay, but he failed to push the hose onto the union that joined it to the existing old hose, and three days later it leaked worse than before. That's when I bought the kit. After reading the entire direction sheet, I made up a new fuel line to connect to the existing fuel line, then assembled them per the directions. The leak was fixed and hasn't leaked a drop, and it's been almost two full months. Considering what a shop or dealership would charge for this repair, plus the fact that virtually all the cars today are using these plastic coated nylon tubing fuel lines, this kit already paid for itself, and it came with enough parts and fuel line to make up a bunch more. ... show more

    • Great kit! Not super sturdy but gets the job done!
Great kit. Comes with everything you need to do the job. I would have given it 5 stars but the compression tool is kind of cheap. Worked great for what I needed. I ran all new supply and return lines on an old 92 ford tempo that I was throwing together as my sons first rattle trap since his birthday was just before the snow flew. I'll get something better after I am sure that he can drive in Ohio's weather. The product has all of the connections and tools to make them and disconnect them. I went to several automotive parts dealers and they could not give me a solution to replacing the lines. Once again Amazon to the rescue! I did buy spare lines made by Dorman as well in case I ever needed them in the future. ... show more

    • Fuel line repair kit.
This kit will get you back in action for fuel line repairs. The clamping jig could be better but it go the job done.

    • The fitting I needed was in the kit
I could have improvised on the tools to get the pieces together. But I used the tools in the kit and they did work. But a heat gun to soften the plastic is the real trick. I really only needed 2 fittings and a piece of hose. It is a shame to have to buy a whole kit. I haven't tried to re-order any fittings yet from the numbers in the kit. So it may be possible but I didn't have the numbers previous to the purchase ... show more
