Fuel issues?

Just put a 2018 5.4 motor in my 2004 f150. I've changed coils, MAF sensor, air filter, and O2 sensors. I'm still throwing P0172, P0175, P0138, and P2169 codes. What should I do next?

You want us to look up the DTC's ? I recognize the lean codes. double check for leaks including the air box.
