When I replaced the fuel filter on my C280, I just unclamped the filter and carefully unclamped and pulled the fuel lines off. A good amount of fuel will spill out of the line but there was no significant amount of residual pressure. Just be careful, the fuel that is in the line from the engine to the filter will dump all of its contents out pretty quickly then it will stop when it is empty. Then reattach new filter and hoses and you are done. Larry Bible's description of the fuel filter location is correct for the 202 chasis.
