I need to replace a majority of my fuel lines for my two stroke equipment. Does anybody know the majority or the two different standard sizes of hose that's used for most Newer Husqvarna and Stihl and older (not too old) Echo? Figure URL link below would cover it for now, but I want to know the standard size so later I can buy it in bulk. https://www.amazon.com/gp/product/B06ZY2B539/ref=ox_sc_act_title_1?smid=AYI27JSX7SHMW&psc=1 Man when these hoses get hard, they get hard as a rock. Geez. Thanks for any help.
