Need to take it to a shop, because the lines are small, and big box stores wont have the correct types/size. Also, a diagram won't help on correct lengths and routing (lack of detail usually). Lines go through several small holes in and around the casing, and the tank, filter section and carb has to come out and such. Will save time, money and aggravation going to a shop and dropping $30. That's what I would charge you (lines included).
