Guide 2002 protege5 error code P0171 and P1569

Hi, can you specify where is that rubber hose? I think I have the same issue here. Thanks
I'm headed into work now, but I can get to it later tonight. The rubber hose I was referring to is on the top of the engine towards the dash side of the car near the pcv valve. The hose is a little smaller in diameter than a number 2 pencil.
