Fuel gauge in a 65 Dart

Hello Redfish. Good to know!! We pick up valuable information each day on these old cars. Thank you for sharing your information. Seems like many early a-body owners battle the fuel gauge issue, but got it figured out...finally.
A seasoned master tech from a Dodge dealership in Ohio moved here and worked with me at local ford dealership. He taught me much, including the instrument voltage limiter inside a 3 post gauge. That was early 1980s. Some earlier models had the limiter was inside the temperature gauge instead of inside the fuel gauge.
