(Caution: Professional Installer... Do not attempt this at home!) Kyle dove right in, explaining the difference in fasteners for the A/C and heater hoses, between AN-6, AN-8, and AN-10 hoses and fittings, and how the unobtainium crimping tools worked. He then proceeded to measure and cut the hoses to be routed over the inner fender, thus hiding the majority of the connections from sight. Can you do this? With the correct tools (and an excellent teacher like Kyle), of course you can! Is it worth your time and investment in tools? For the average home builder, probably not, but that's your decision. It's important to note that professional installers will have not only the knowledge, but also the proper tools to make it right the first time. As for us, we'll stick with Kyle.
