Be easy with this job, dont force assembly in or out, it may bend or break in different places. I run a walbro pump so assembly looks a littLe different but this is the touring assembly. Go easy and make sure gasket goes back down correctly, suggest new gasket along with filter. I have reused the gasket successfully, also new crush washers for fuel line with correct torque. The small nuts that connect to tank as turbo said above dont over torque, people have snapped the studs off.
