Electrical Problem
1961 Corvette
I have had this problem for 30 years but never spent too much time investigating it. Now I have decided to try to fix all of the small problems with this car. When I step on the brake pedal, the fuel gauge needle jumps by a 1/4 full and then returns to base with release of pedal. No other electrical problems, all lights, horn, charging etc. working.
Where should I start my search... in the brake light circuitry, fuel tank sender, look for grounding problems ?
Thanks
Tom

It'll take you about 1/2 hour to resolve.
VERY common problem on C1s and my 61 had the issue before I fixed it

Has nothing to do with acceleration or deceleration, but it's probably the most common electrical problem for the C1 cars. Run a separate ground wire and you'll be free to turn your attention to other issues.

Thank you gentleman. The "dancing needle" is exactly what I have. I need to replace the fuel tank vent hose so I will run the dedicated ground at that time. Thanks for saving me countless wasted hours trying to run down this issue!!

The bad thing is that's one of the first things I did to my 1960 after reading JohnZ's. article about it. I'm going to blame oncoming senility.
