The old vacuum regulated return style fuel rails will pull down the PSI, and it may be low on the newer stuff too with a factory pump, but the Corvette filter/regulator is set at 58psi, so as long as your pump puts out that much, that's what you'll have at the rail.

I'm aware of this, but was trying not to confuse the kid. They will work with regular fuel fine.
