you said pressure at 63psi turn key. you also want to do a hold test, to see that it holds pressure, i don't know what the specs are for your vehicle though for the hold pressure, but if it doesn't hold after about 5 minutes or so and is below specs, you then want to do test again and this time clamp off the line either before or after the gauge, to determine where the leak down is, if you clamp off the line before the gauge, and it still leaks down then possible leaky injectors, leak leading up to the fuel rail, or around the fuel rail, or bad pressure regulator, if you do the test with the line clamped after the gauge and it leaks possible fuel line leak in the feed line from the tank up to the gauge somewhere or bad check valve in pump.
