Good luck picking one up at your FLAPS. Those guys will ask for make and model, not your resistance vs pressure profile. I had to test my gauge with a variable resistor to get the resistance range of the gauge. Then I searched high and low for someone who could tell me what a sender was resistance wise at a certain pressure, it is not written on any box I looked at. Finally found one for a jeep that worked after I added a tad of series resistance to get the gauge to read spot on.
Wrenchbender is correct. The manufacturer should tell you what sender to use or sell it to you in a plain white box with big markup.
