Engine Error codes
We replaced the fuel rail yesterday on a friend's 2017 Ultra Limited after he broke it by trying to remove the tank w/o disconnecting the fuel line. We swapped the injectors to the new rail, buttoned everything up. Started up fine. Today, he is getting these codes:
P264 - rear injector high pressure
P261 - front injector low pressure
What could be throwing these codes? We connected up the connectors to the injectors correctly. We didn't note which injector was on which side, not thinking they were front or rear specific. Are they?
Thanks in advance for the help.

Low and High referenced in the codes are not pressure, they are rather electrical references, i.e., resistance, voltage, amps, etc.
I'd start by disconnecting the connectors, check for contamination, check the barrels and pins for distortion, shoot them with a little WD-40 and cycle the connectors (connect/disconnect) a few times and then see if the codes re-appear (after clearing them first of course).
