I removed fuel cap, removed Filter clamp nut & used penetrating oil ( half Kerosine-half Transmission fluid) to lubricate hoses & facilitate their removal. Compress clamps with pliers & slide back- Remove & replace fuel filter be sure you install in right direction ( in-out). Might consider replacing clamps with SS Screw type to make future changes easier? spilled very little fuel but you should wear safety glasses as debris/dirt from chassis underneath can get in your eyes.
