You can not just cut up some fuel line from the auto parts store and use hose clamps to connect to the fittings. The fuel lines are under high pressure and eventually they will fail. The hose to fitting connection needs to be a crimped fitting. The factory replacement rubber hoses are not necessarily compatible with ethanol. That is the reason I went with lines made by Len, as they are ethanol compatible. Plus it is easier to replace the tunnel line sections with Len's because you can pull the new line in while pulling out the old line. The factory polyamide tunnel lines have a 90* bend at the front where the it transitions to rubber hose. Len's tunnel line are straight with fittings at both ends. Len's front rubber hoses have a 90* metal fitting that connects to the front end of the tunnel line. If the factory tunnel line is used, you must connect a draw string/wire to the aft end, it gets pulled through the tunnel as the old line is pulled from the front, and then the new factory line is connected to the pull line and is pulled through the tunnel from the rear, hopefully not getting hung in to many places.
