I have one sticky temp gauge on my 87 mainship with twin 270 crusaders. The engines run at 160+/- and both gauges do read Ok but one is sticky and needs to be tapped quite a bit which makes me nervous. I'd like to replace it. Its a Faria but I can't find an exact one anywhere on the internet. Does anyone know if I can use any replacement Faria gauge or will I need to replace the sending unit as well? any thoughts on faria versus VDO? I assume if switch to VDO will surely need to do sending units too. Thanks
