Real EE advice solicited

My first question is why would you select and think this sensor is rated and designed for liquid service. It's not, it's designed for gas (dry air at that) pressure only. From the datasheet:

The MPX2202/MPXV2202G series pressure sensor operating characteristics and internal reliability and qualification tests are based on use of dry air as the pressure media. Media other than dry air may have adverse effects on sensor performance and long term reliability. Contact the factory for
information regarding media compatibility in your application.

You have first focused on the electrical side of this sensor rather then first checking if it's compatible with the media you are trying to measure.
