I have the MPX4115AP, it can use a plastic pipe for a remote connection to a sealed tank.
I cannot say if its what you need.
I would be carefull of anything besides air.
Quote from data sheet:
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.
