I am looking to run a 0-5v input into flashscan to log and playback my fuel pressure. I have found this http://www.racerpartswholesale.com/stewarn23.htm sender STW114875 100 PSI electric fuel and oil pressure, 1/8" NPT for $28.06

Does anyone know if this will output 0-5volts or can anyone recommend a electronic fuel pressure sender/sensor that does?

The SW is a straight resistance type sensor. It would require another resistor to act as a voltage divider, a regulated 5 volt source (easy) and a fair amount of work to derive a transfer function.

This looks more promising. It still requires a 5 volt regulator, but has a known transfer function and appears to be A/D friendly. I've already contacted someone at Mototron and will report back asap.

Expensive at $77.56, but if it will work better and easier, so be it.

Well looking around more and calling a few places Kinsler Fuel Injection uses these http://www.dakotadigital.com/index.cfm/page/ptype=product/product_id=117/category_id=-1/home_id=-1/mode=prod/prd117.htm

Even more expensive at $125.00 but thats what kinsler and Dakota Digital Reccomended. Part # SEN-09-4

Will that work?

Hard to say without more technical data. The basic requirement is an output in the 0-5 volt range, preferably linear, and the ability to withstand pressurized fuel.
