I went with autometer because it matched my other gauges. Would not recommend it. Many glitches with operation.

I have the Autometer and about 60% of the time it works 100% of the time...

After going back and forth with tech support and doing all they suggested I installed a toggle switch in the power wire. When it sticks in warm up cycle, or goes to default of 14.1 I turn power off and back on and it starts working.

I have had issues in the past with sensors getting wet.
After installing the Innovate HBX-1 bung adapter, I have
60 hours on the clock with no problems!
