Neither of the pumps is a real primary they alternate based on gas level in the tank and second one turns on with fuel demand. I keep meaning to make a thread about this because its pretty interesting.

FYI Proto makes a in tank fuel system on top of 997 stock pumps that supports over 1k whp on E85. I run the system in my 996 and it works flawlessly.
