What style fuel line is best?

yes, very easy. wrap tightly with Teflon plumbers tape. then cut with a new razor blade, slide the braided sheathing back, thread the ferrule onto the hose, and then slide the sheathing up, remove the Teflon tape and insert the fitting and tighten. just like the directions say, it is easy. earls has a video.
