Make a fixture out of black iron pipe, 1/8 npt bushing on one end and air chuck on other or some such arrangement of your choice. Pressurize it with compressed air. If you want to get fancy you can add a regulator and pressure gauge. Check resistance with an ohm meter.

My compressor clips at 175 psi WAY too much for that
I can check static / not under pressure / with a meter
Thanks 4 your reply TRIP

At my work, we use dead weight testers to simulate oil/hydraulic pressure on aircraft and helicopters for testing,syncing,calibrating oil/hydraulic pressure gauges and torque gauges that translate pressure.. Of course they are rather simple and archaic in design, but still are expensive and not generally used in automotive applications. As Trip had mentioned, I think I'd hook up an inexpensive air regulator to the sending unit plugged into the car harness with a ground wire attached to the body. Slowly, incrementally increase air pressure 10 psi at a time and observe your in dash instrument. If it is close to mirroring the functional gauge then I'd say you are in business.
