hey guys, recently installed a fuel pump in my Camaro which has a split tank w/ 2 fuel pumps (1 transfer pump)

Logging both the Fuel Pump Level Sensor 1 & 2 and got 2 separate voltages on each side. This car has a 19 Gallon tank and I manually put ~10 gallons and the gauge showed closed to E after letting the car run for a bit. Filled up at the gas station and it only shows 1/2.

it it normal on GM cars for the both level 1 & 2 to have separate voltage readings?
