I know what the FSM says. But this is what is real.
Cold start psi is around 100 psi. Once off of fast idle. The pressure drops to around 35~38 psi. The pressure will raise with rpm. It will get to 95 psi at around 5,000 rpm. This is why you can't install a 100 psi gauge. It will be pegged. Have to go with a 150 psi gauge.
My low pressure warning light is set to come on at 25psi on my gauge. The 14 psi in the FSM is just enough to turn off the factory warning light.
