That you will have to design yourself.

Pstorage (and Fstorage) accesses flash by using the SoftDevice API, sd_flash_write() and sd_flash_page_erase(). It reads from flash with memcpy(). And it gets system events from the SoftDevice so that it knows if a flash operation succeeded or not, NRF_EVT_FLASH_OPERATION_SUCCESS and NRF_EVT_FLASH_OPERATION_ERROR.

Pstorage wasnt' designed to be used with an external EEPROM, but if you really need use it, you need to at least change the interface so that it matches with whatever interface your EEPROM has.

I don't understand, Fstorage and Pstorage are software modules.

i want to replace fstorage and pstorage both with external EEPROM?

The difference? In what regard? Pstorage was replaced by Fstorage and FDS, with Fstorage as the backend and the FDS as the frontend. Both Pstorage and Fstorage interface with the SoftDevice by using sd_flash* functions, and flash events.
