After being put aside for a few years, my FTP900 is found to be leaking basically everywhere. So far I have managed to replace the O-rings in the air tube but the regulator is leaking through the bleed hole. The user manual does not provide any diagrams of the internals of the regulator nor any part list so I don't even know where to start. I have removed a retaining ring hoping that the brass component beneath it will drop out but it did not happen. As a matter of fact, that retaining ring is not retaining anything at all but just sitting in it's slot. The model is discontinued so I am not sure if Air Arms will give any support . Any advice on how to go ahead to fix it ?

You either didn't pull it apart or something is missing, here's a pic disassembled. Looks fairly simple.

The O rings should be easy to get hold of, check the sealing face of the nylon insert it may need re machining if badly groved also the brass side of the sealing piston is quite chunky, I re machined mine to be a bit sharper, not quite knife edge but closer than the original profile so it seals better.
