What should the fuel pressure be at the output of the high-pressure fuel pump?
My friend bought a boat w/ twin 2009 250's, Stb runs good (pressure is 40+ psi consistent), port bogs down at ~2500 RPM (pressure is ~28 and seems to be erratic).
My bet is it's the High-Pressure pump on the port motor.
Any opinions?

Maybe not. Check the fitting at the fuel return fitting on the vapor separator. There is a small cone filter which is known to get clogged. Remove and clean or replace. Be careful when removing the hose so you do not break the plastic fitting.
That's the vst filter....part # 0362268
