[QUOTE="cidsamuth, post: 16579560, member: 110091"] So, not interested in debating whether the gas testing kits are better, as I've already installed the sensor. Just curious if what I'm seeing is normative. I have the Aeroforce sensor going to an analog input of my Interceptor. Right now, I'm not driving the car because of salt on the roads, and it has pump 93 (E10) in it. With the ignition "on," and the pump running (engine off), it is reading 11.6% steady. Fuel pressure (return style) is set to 48 lbs. I'm honestly not sure whether the E10 these days in my area tends to be even higher than 10%, or whether it's actually 10% and the 11.6 just represents sensor/gauge standard error. But what's most curious, when you start the motor and let the engine idle, the reading fluctuates between 10.5 and 11.2. Pressure is still at 48ish. While I realize it is normal for the reading to fluctuate like that +-1%, why would it be rock steady (and higher) when the engine isn't running and the pump pumping fuel at the same rate? [/QUOTE]
