Thank you. This seems to be the sensible solution. Temperature
compensation, gasoline compatible and inexpensive too. Without g-force
compensation but that is probably not so useful anyway. I am glad to
understand that the long lines between panel and sensor do not pick up
noticeable noise.
What kind of averaging time did you set the EIS input to?

which provide a 0-5 volt output for 0 - .87 psi. They are a differential sensor
so the liquid side is connected to the water drain pipe from the tank bottom
and the other side is connected to the tank vent. They only require a 5 volt
supply that we take directly from our EIS. We calculated that a full fuel tank
will have a head of pressure equal to about .4 psi. So we programmed the
EIS so that 0 - .4 psi gives an output of 0 - 100.
