Was daily driving and had the code P0171 lean bank one pop up. I pulled over and popped the hood to see this (photo attached). Once I got home I went over the engine and found the hose connected to the back of the intake completely off. I went ahead and fixed it and reset the code. Drove fine 3 days and the code is back. The only thing I can see that changed is the aux fuel hose so I'm assuming it failed. I'm really hoping stratified will sell me just the hose. I'm very curious as to what happened and if anyone else has had such happen.
