How do I change the gas hose on troy bilt trimmer?

Go to your local lawn equiptment dealer. They will have a kit with two different sizes of hose and a fuel filter. Simply take off the gas tank lid, and empty the gas/oil mix out into a suitable container. Pull the fuel filter out of the tank and disconnect it from its fuel line. This is the fuel supply(inlet) line.Pull the hose out of the tank and disconnect it from the carburetor.
Find the proper size of hose in your parts kit, measure it and cut to length. Push the new hose into the gas tank from the outside, grab the hose on the inside with a loooooong pair of needle-nose pliers or forcepts and work it over the NEW fuel filter nipple. Then connect the loose end of the fuel hose to the open nipple on the carburetor. Push the new fuel filter into the tank and go to the other fuel line.
This is simpler because it only connected on one end. Simply pull it out of the tank, pull it off of the carburrtor, measure and cut to length, and push it through the hole in the gas tank, and attach it to the carburetor.
Fill the gas tank with the fuel mix and with the ignition switch in the OFF-OFF-OFF position, press the primer bulb several times 'til fuel flows back into the tahk. If the fuel flows through the last line that you installed, everything is good to go. Relace the gas cap on the tank and you are done.
IIIIFFFF the fuel DOES-NOT flow through that last line, switch the hoses at the carburetor and that should correct that problem.
