How do you access a fuel filter on a 2002 Harley Davidson motorcycle?

The first thing to do is drain all fuel from the gas tank. Begin with turning the valve of the petcock to OFF. Then the fuel hose from the petcock to the carburetor is loosened at it lower end and the fuel drained from the tank itno a sutable vessel. Next, remove vacuum hose from the nipple on the back of the petcock. Turn the valve to "Reserve". Drain the reserve gas out from the tank by using a vacuum pump connected to the nipple. When no fuel is left remove the vaccum line and the pump. The next step is to remove the petcock from the tank. This is easily done by loosening and then removing the nut that fastens it to the underside of the gas tank. When you remove the petcock you will see a long screen in the form of a cylinder come out of the gas tank. Clean or replace the screen filter. Reassemly is the reverse of dissassembly except you don't need to use the vacuum pump again. Note that the threads of the petcock should be coated with a suitable sealant that can withstand gasoline. Also replace the gasket under the nut holding the petcock in place. Insert the assembled parts into the gas tank and then tighten the petcock nut well in place. The hoses are finally attached. Now you can fill gasoline in the tank but check carefully for leaks. It's no joke getting a gasoline leak right onto the hot engine.
