I dont think gravity feeding would work because the waterline in that fridge goes from the bottom of the fridge to almost the top.
(The pressure tank that I have in the basement is set to 50 psi and it kicks in at about 42psi. That is why I was thinking I could set it to 50psi it would be the same as the water pressure in my pipes.)
Never had any quality issues with standard air compressor making couple of gallons of coffee every morning, but I guess you could put one of those filters/separators on the output.
I don't have the science skills to explain the volume/pressure relationship, but in my experience, if you have the keg anywhere near full, you need 90lbs or it runs out of steam before all the water is dispensed. All about head space for the air. More air (volume)-less pressure needed, but you have less water. Water was harder to get than air, so I filled them pretty full.
I took this thingy from Kragen and gas connector to TruValue and got flare adapter to go between. Makes solid and rigid chingadera to pump it up. Get it here too:
