1966 Rover 2000TC - AC Fuel Pump Disassembled

A quick overview of the AC mechanical fuel pump on the Rover 2000 TC. It started leaking recently, dripping onto the ground, so I sourced a rebuild kit. The gaskets in the kit don’t quite look right to seal the pump to the engine, but I’m sure I can make something work. The old diaphragm is definitely degraded by ethanol, and there’s a fair amount of grit and/or silt in the pump body, so it’s nice to have it apart to clean properly. 
It’s not clear how I am supposed to get the old check valves out to replace them, but hopefully I can find a tutorial online.
