I bought 6 gauges of the Lido series from Teleflex Marine for my boat, a Wellcraft Excel 20 SX engine with Volvo Penta 4.3 l v6. Unfortunately, the fuel gauge that I received does not work, yet the old works great. Also, there is no temp gauge for inboard of the Lido series, so I bought the temp gauge for outboard and it does not work either, yet the old works great. So, 4 of 6 of my new gauges work very well, either Voltometer, 7k RPM Tach, Oil Pressure 0-80 psi and 65 Mph Speedo kit. But, my dashboard looks like with old and new gauges.
