Dan what engine is in your truck? I guess that would not make a differance but just curious. I am using an LM34 for the temps in my pickup. And an MPX5700DP right now for oil pressure. The 5700 is a differential pressure sensor but I am going to change to an absolute sensor soon. I had the 5700 so used it. Anyway I power them off of the FB and just read the voltage. Take the voltage off the LM34 times 100 and you have the temp. And the 5700 puts out 4.5 volts at 100psi. I am using the 2907 for the speed and tach but they are not connected yet. My gas tanks are a little easier to read. They are 0 to 90 ohms. They are the only ones that I use a voltage divider for but I still use the 5 volts off of the brain. Just thought I would let you know a different way of doing things.
