Looks like it cleaned up well. On that picture of the gas tank from the left side top it looks like you also have a fuel filter in the normal place to the left of the picture there. That is the one in the diagram, a cylinder with an arm out either side top and bottom. That straight filter looks like something someone added. Anyway you should check that and save yourself the trouble of adding a new one in the engine bay and maybe eliminate the extra one next to the tank. Unless that is a rollover valve. Being on top it is unlikely to be a fuel supply or return which are both on the lower half and side of tank.
