I want to be able to send this to the PDM as I am pretty tight on inputs to the ECU and the PDM is also in the CAN stream obviously. I can apply filters to the signal at the Dash so I am not worried about dampening the signal. Rough idea of how I go about this? Will I be able to transmit the value over CAN?

I did it with 0-90 sender. I found 10ohm in series to bump the base up and 22ohm pull up to 5v gave me best resolution with minimal current draw. The sent that via CAN to Emtron ecu
It should be doable, but what ecu and what dash are you currently using. That may play a factor in where it gets wired to.
if it is ohm I’ve had good luck with haltech fuel level conditioner.
