Gauges for Capacitive Fuel Sender
I used the UMA 1-1/4 in dia dial gauges (ACS p/n 10-00040) with the Vans (Princeton) capacitive senders. The 2 set point (Empty & Full) senders are quite inaccurate because of the tank shape, you really need to get the 5 set point (E, 1/4, 1/2, 3/4, F)senders to get meaningful indicators. I have connected the 0-5V sender signal into the GRT efis display & used a 10 pt calibration curve to provide a very accurate fuel level display, so I just use a "correction card" beside the gauges.
