2001 Chrysler Concorde Engine Light

I'm trying to get my vehicle's inspection done but after taking it to Pep Boys, they told me they can't inspect it as the engine light was on and pulled codes for me. P0171, and P0174. These both relate to the system being too lean, which I'm told means that the engine is getting air from somewhere it shouldn't be. Automatically Pep Boys told me it was a Fuel Pump, but I work with people who are certified mechanics and those codes that are pulled are only saying it's only on Bank 2 that the engine is lean, which could not possibly be the fuel pump since that would show it failing on both cylinder banks. I changed the fuel cap, thinking that maybe the seal was shot, but same thing. The other suggestions, thoughts and options I've looked at are the Mass Air Flow sensor, which it turns out my car doesn't have one. I cleaned the MAP sensor as it was full of grit and it was leaking so I also replaced the O-ring that seals it. I had the codes wiped with a scanner but still the same thing. My O2 sensor was good, and the only other thing I can think of is just looking around for a loose hose or a deteriorated hose.

I need help as soon as possible since my current inspection runs out at the end of this month.

Thank You.
