Default Low Fuel Pressure

What is the symptom of overheating? I have a intank lift pump and my upstream fuel pressure is 8 psi at idle and under max load it drops to 5 psi. My warning light flashes on. The lights pressure switch is at the vp44 inlet banjo bolt. I have not had issues but I do plan to put a FASS lift pump and remove the tank lift unit. I do not have any ill symptems to date but i do back off allowing the pressure to satisfy the warning light sender. I am new to this cummins.
