And a side note, here is a mini ascii diagram of the setup:

S is the sensor:
(ZZZZ) are the tanks:
G is another mini guage:
* is a place holder(empty space)

S-(ZZZZ)-|--(release valve)
********|---(to compressor)
G-(ZZZZ)-|

ETA: Ascii art doesnt work with spaces!

Does anyone know how the analog sensor would be used? i have seen no documents at all on the topic. I do have the sensor from last year with the 2 screws, which i can use if worse comes to worst.
