Auto Meter 3327-M Sport-Comp Electric Metric Oil Pressure Gauge - High Performance Vehicle Monitoring for Racing & Off-Road Use

Gauge worked fine for about two weeks.However the senders failed already on both temp and pressure gauge. I've owned the same gauges on my Skyline for 3 years with no issues. Used these on my WRX for 2 weeks...both fail. I could understand one sender failing but both..... (pressure sender was also remote mounted away from engine/vibrations on its own).ohm and voltage tests dont help, re-did grounds, power supply is steady and never dips past 12v even at full load, re did wiring
