Got all the gauges back in working order. Fuel gauge was easy with just the 6v reducer needed and sending unit seems good. Oil pressure was straight forward after i drilled and tapped a fitting off the oil pan/cooler block off plate. The temp gauge was a little tricky. I went with the old style capillary tube sender but i had to get a aftermarket LS block coolant drain plug and drill and tap it to 1/2npt to accept the bushing/seat to fit the sender. Works well now. I got crafty with the amp meter and retrofitted a voltmeter in its place but used the factory face plate and added 2 small marks with brown sharpie to identify 12v/16v. So basically “0” on the gauge is the perfect 14v charge condition. Im very happy how it all turned out and how stealthy it is and appearing stock like the rest of the truck hehehehehe.
