    Fuel tank pressure help

    Guys, could use some help with fuel tank pressure (2000 T/A).

    What is the conversion to get pressure from the logged voltage?

    Also, what do you guys see key on from the voltage? Need to fix some evap stuff an I want to verify pressure sensor function since the tank will be down.

    I am at 1.54-1.56 V key on, blew a little air in the filler and it made it's way closer to zero. I didn't really expect that so I want to confirm.
