Gas gauge needle flutter - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Here's a couple more idea:

A) You mentioned you installed a replacement tank. Your 1963 gas gauge needs a 30 ohm sending unit. Is the sending unit a 30 ohm or a 90 ohm?

B) I had a similar problem with the Tachometer needle in my '69 Camaro and I put a 10K, 1/2 watt resistor in the line and it calmed down the erratic readings. I don't know if this will help but I do know ithe resistor was only a couple bucks @ Radio Shack. Might be worth a try?
