SG9Forester2.5xt

Hi, im new to Subaru ownership and I recently had to replace my in tank fuel pump on my sg9 Forester 2.5xt. I went with an upgraded Walbro 255 and replaced the in tank filter at the same time. Car now runs but I’m getting a few codes. I have tried cleaning the MAF. I’d appreciate any advice as I’m not sure what step to take next.
