2018 Kenworth T270 PX-7

I know this isn’t really heavy duty but I figured I’d ask here. I’m looking at purchasing one of these. 191,000 miles. Looking for anything that should be done immediately if it passes the pre purchase inspection. Also I can’t for the life of me figure out what high pressure fuel pump is on this. I know it’s a Cummins so I would think it would use the CP4 like the rest but I’m just looking to be sure.
Any help is greatly appreciated.
