Any suggestions on a sensor I can get to log fuel pressure on my 2003 Grand Prix GTP through my EIO? I assume I would need an adapter to hook this sensor up to the schrader valve on my fuel rail and then run the wires in and connect them to the EIO. Also, I assume the voltage curve would not be linear so how would I figure out the proper formula for the scanner?
A bit of googling brought up this one, that's a cheap price. It should work. And you will probably need a pipe fitting.

That sensor maxes at 60 psi, I don't think that will work.
Woops, sorry, try this one.

They also don't have a 0-5V output to connect to the EIO. I appreciate your help, but I was hoping I could get some input from someone who has done this. Specifics on sensor, adaptors, and the voltage curve to get an accurate reading.
To convert 4-20 ma to 1-5 volts will require one 250 Ohm resistor.
Of course, if anyone else has done it, perhaps they will chime in. If not, I can probably help you.

I'll be hooking up an Autometer FP gauge as soon as Speed Inc gets me my fuel line, and tapping into their sender. I've been told it has a linear output, so I'm going to try and relay that to my EIO. I'll let you know how that turns out.
I rigged an electric sender and gauge to my Actron
mechanical w/ Schrader. At one time I had the sensor
info but I'm far from home at the moment. I'll take a
look at it for P/Ns when I get home but I do recall
it is, there is a pretty standard sender. Don't know
what the characteristic is as-wired, the gauge does
that housekeeping, but I bet there is something
worth tapping.
Use a stock oil pressure sensor - already an NPT fitting.
