Ordered temperature, volt and oil pressure gauges from Dragonfire around a month ago. Received and installed the temp and volt gauges within a week. Everything good but the temp gauge wire was too short. Chris at Dragonfire called me and said that the oil pressure gauges were back ordered and would I mind waiting a week or so. Told him that was fine but still haven't got the oil pressure gauge or the shifter that a ordered a week later. But I noticed on the Dragonfire website that they don't show a sending unit for the oil pressure gauge like the one they show and the one they sent with the temperature gauge. Has anyone out there installed the Dragonfire oil pressure gauge? And does it in fact come with a sending unit?
