100 PSI Pressure Transducer Sender Sensor with Connector - 1/8 inch 27 NPT Thread Stainless Steel Pressure Sensor for Oil, Fuel, Air, Water

Replaced my Auto Meter sender that failed with this one. It worked great!

Used it in place of buying the $160 holly transducer. It surprisingly works great and was good craftsmanshipUsing it for fuel and oil pressure with holly terminator x fuel injection

I've been through a couple of these now, and had the same failure mode on both. I've tried to use them for fuel pressure in a "normal" (44 PSI) fuel injection automotive environment.On first install the pressure reads very close to accurate, as compared to both the fuel pressure regulator spec and a separate analog gauge. When testing again a few days later the pressure reads significantly lower (ie the voltage output is lower); like 30 PSI instead of 44 PSI during initial testing. The output still seems to be proportional to the pressure (lower pressure -> lower voltage) but way off from the spec for the sensor.I love that these are cheap, but they're clearly not trustworthy in any environment that depends on them for operational logic. Not sure if the problem is with exposure to liquid or exposure to fuel specifically. Either way I recommend avoiding them for automotive purposes.

Sensor works well, accurate psi readings and built very well.Priced below other well known names sensors.Purchased another one very please with this sensor.

I engineered an analog circuit to process the output from the sensor and was ready to hook it up for testing. There was NO wiring legend. There was a black, red, and green wire. I looked at two similar products on Amazon that I believed were the same sensor being sold by different companies. Both had wiring that differed making no sense. Trying these configurations did not work. Finally I found the correct combination. Green in the other sensor was ground and red the output. But in this product green was output. Only in China would they mess up consistency so badly. The circuit worked well and the sensor seems a good one for the money!
