One issue with the newer GMs and gravity feeds: If the computer doesn't see the fuel gauge decrease in a 100 miles of travel it will set a "Pending Code" and if you continue it will throw a "Check Engine code".
I'm running a Scan Gauge so I just clear the pending code when my fuel gauge drops to zero, which is approx every 100 miles until my aux tank is empty.
