That might be an issue with the insulation washer, Lugnutz, where do I get one of those? I also changed the actual gauge got it from Classic Parts. It was half full when I got it installed. When I went to the gas station and put 11 gallons in it it now reads Full. I filled it up so I think I have resolved the issue. Thanks for all your help.
Thanks to Woog. He answered my original question. I'm glad I didn't have to do all that to get the gas gauge out and remove it. Just 3 1/4 inch hex screws to get the gas gauge cluster and oil presser cluster out together and then replaced the gas gauge and it is working, I think. Ha Ha
Thanks again for helping me resolve the gas gauge issue...
