This is the tale of my Stihl FS-56 Trimmer vs. Husqvarna 125B blower. I bought the blower new, 10 years ago. The trimmer I acquired from my father. It is at least 30 years old. They both have always used the same fuel -- which up until this year has been e10 89 octane mixed. The only thing done to the Stihl, has been new plugs every now and then. It's still on original fuel filter, line, carb has never been touched, etc. The Husqvarna has eaten through it's fuel line twice -- currently on it's 3rd. It's not a real fun job to replace. What gives? If I bought fuel line from Stihl, would it last? Or, is this simply a case of "they don't make things like the used to"? This year I switched to pre-mixed fuel -- since both only go through about 1 tank/season.
