N54 port injection question

Do you have to run 2 fuel pumps for port injection or can you run 1 big fuel pump to run it?

Generally speaking, if you need enough fuel for port injection you'll need to run 2 pumps but yes, you can run PI off of one large pump like a Walbro 535

Yes, all the PI kits will come with lines to T off with one side going to the HPFP and the other to the PI rail
