I have been having some issues with my gauges now that I have my truck on the road. I was able to use the below thread to correct my Temp Gauge issue, Thanks Rudi. My question. My fuel gauge has been tested per Rudi's thread and it works fine. I installed a new tank and a new sending unit from CCOT during my rebuild. ON a hunch from this thread I pulled the new sender out and put in my old one that came with the truck. BAM, it worked like a charm. It appeared to register the correct amount of fuel in my tank. I tested it before hand using the 3 watt bulb trick from Rudi. Can anyone tell me why all the NEW sending units etc... will not work with the gauges in my cluster? My challenge now is the old gauge does not completely seat properly and I can't grind the edge of the tank due to metal shards and explosion concerns. Will have to noodle that one for a bit. Would love to hear if others have run into this and how they have compensated. I did try double grounding etc... and this did not work.
