Unreliable quality: Electrical

Bought two (one for each engine). One works fine, the other died a few hours later and has only worked sporadically ever since.

Pros
  • Sensors
Cons
  • Nothing here

80 psi, US drag, dual rudder gauge. Is working!

I installed this on a Cummins 6BT on my boat when the old sensor on my left hand engine failed. 1-wire installation, 1/8-27 NPT, accurate readings at both stations. I have faria sensors top and bottom. You can't ask for more from him.

Pros
  • Automotive
Cons
  • Fits

This transmitter worked great. I have 2 fuel gauges on my boat.

This transmitter worked great. I have 2 fuel level sensors on my boat, this sensor is perfect for this application. At zero pressure the resistance drops to 120 ohms and approaches zero as the pressure increases. You need to pair your sensor with the transmitter. Some start with low resistances and increase as oil pressure increases, others vice versa. If you put in a new sensor and your gauge seems to reverse, ie oil pressure drops as RPM increases, wrong sensor. Measure the sensor you have if

Pros
  • Lighting and Electrical
Cons
  • dim
