Kavlico pressure senders off scale high

[airguy]

I am approaching first engine start, I have dual Skyview with EMS and my fuel pressure and oil pressure both show top-of-scale with no pressure on them. My manifold pressure gauge indicates correctly, and all three share the same power source and ground. Do the oil and fuel pressure senders need calibration before use?

They do not require calibration. Check to make sure you have picked the correct sensor (which includes working range) in the sensor mapping setup. This is likely where you have an error.
