The fuel filter is located next to the fuel tank on the drivers side of the car. Raise the car as required and support on jack stands. Wear appropriate rubber gloves as you may get gasoline on your hands. Gasoline is very flammable so have a fire extinguisher handy in case leaking gas should get on fire. Needless to say you should not smoke while changing the fuel filter. There will be fuel in the filter, have a suitable container to drain it into.
Then use appropriate wrenches and loosen the inlet fitting next to the fuel tank. The fuel line is under pressure, so loosen the fitting carefully and have a rag there to catch the escaping fuel. Dispose of the rag in a proper manner. Once the pressure is released finish taking the coupling loose and then loosen and remove the coupling on the outlet end of the filter. Installation of the replacement fuel filter is the reverse of the above.

If I had to replace a fuel line I would get a replacement out of a car in a wrecking yard and install that.
You don't unclog the fuel filter, simply replace the whole canister with a new one.
