Hello and thank you for using JustAnswer. My name is XXXXX XXXXX I will do my best to help you with your Chevy problem.

There is only one gauge for this truck. Since you have different readings with the new sending unit, the best thing to do is to connect a manual gauge to the oil pressure port on the engine, then run it. You can get a basic manual gauge at most parts stores for around $10. This way you will know for sure what the engines oil pressure is.
