Persistent P0393 code 2008 v6 Cayenne

[mylai996]

Have a 2008 Cayenne base model.  Started smelling fuel and received check engine light with code P1110(very small fuel leak).  Turns out my fuel filter flange developed a crack and fuels was shooting out from the crack, thus the fuel smell.  Replaced the fuel filter.  However, one of the fuel lines that attach to it from the right fuel pump has a bad clip(which I did not know at the time).  Upon testing after replacing the fuel filter, that fuel line detached from the fuel filter and the car stalled.  Re-checking the install, I now see the detached fuel line from the right fuel pump.  I kind of fixed the clip on that fuel line that had detached from the fuel filter and it is now staying.  Started the car and after driving for a few days, check engine light comes back with the following codes - P1110(very small fuel leak), P1090(small leak), P0393(system too lean at idle bank2), P0391(system too lean at idle bank1).  Bite the bullet and bought the right side fuel pump that comes with the fuel line that attached to the fuel filter as I suspected the clip on that fuel line is still not doing the job properly.  Replaced the fuel pump and re-attached everything.  Test drove the car and still getting check engine light with code P0393(system too lean at idle bank2).  Other than that, car drives normally.  I am at a lost to where to look into.  Any suggestions would be greatly appreciated.  Thanks in advance.
