So guys I feel like my fuel pump needs to be replaced because on top of the 2AAF im now getting 29E1. Which is a fuel mixture error. What do yall think? And which pump do I replace.....tank pump or the one on drivers side of motor?

There isn't a pump on the drivers side...that is a filter and regulator assembly.
29E1 is too rich...what tune, map, and fuel are you running? That is more tuning and fuel mix related than fuel pump. Logs...logs...logs....

2AAF? On its own, no other fuel system codes? In that situation, you ignore the code. It's not something going wrong, it's just the DME being overly sensitive to LPFP demands. See the TSB a few posts back...
