I replace the fuel lines on EVERY build. I go to a lawnmower shop and buy the fuel line made for weed eaters and such. They are a yellow color. Also I check the fuel cut off after I put gas in the tank and before I hook it to the carburetor to make sure it cuts off. I use the factory filter till break in is finished then replace it with a bullet type filter. I know Advance has them, sure O'Rileys and Auto Zone carry them.
