Correct.
I know cummins uses upwards of 30,000 psi on there common rail systems. At these fuel pressures, it is vital to keep any moisture out of the fuel. Since water is none condensable, it will blow the injector tip right off and wreak havok. A fuel/water seperator is mandatory. Maybe this is part of the problem with gasoline engines?
