Thanks MarkerInbound.
I found the >FUEL PMP STB L and >FUEL PUMP STB R EICAS advisories in the FCOM I have, as you mentioned. Makes perfect sense now why they are not armed on the ground.
I do wonder why the advisory was implemented in the first place for a fueled HST with pumps ON (ARMED) on the ground. Would make sense to have it set up properly before departure and just wait for the logic to activate the pumps.
