Question Walbro Fuel Pump Question!!

Ok so I just installed the walbro 255lph fuel pump and I started up the car and everythin worked fine but I could here the pump humming while i was at idle. I didnt have the backseat put back together or anythin so i guess im just wonderin is that humming normal? is it because its a larger pump so its louder? or maybe just because I havent put the seat back? I feel like an idiot I guess I just didnt wanna put everythin back if I had to fix somethin ... anyway if anyone has experience with this please let me know if this is normal!!! THANK YOU!!

More flow?! That's one concern I have with a bigger pump since naturally an RS-T don't have the circuits to run the pump at different speed.
