Fuel pressure

Not sure if this is where I need to post this or not but I need help trying to figure out how much fuel pressure there should be for a 1988 F-800, 429 motor, electric pump. Does anyone have any idea?

For non-DI EFI gasoline engines, Ford usually sets a nominal 40 PSIg. This is measuring the pressure with the manifold vacuum reference removed.
