Fuel Gauge "Bouncing" - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So I've searched this and found a few but, I just want to be clear on what I need to do before I have to pull the tanks.

The problem is once the truck is running the fuel goes anywhere from 1/4 of a tank to full and bounces all over the place. So is it the gauge? The Sending unit? I don't believe it's a ground near the gauges, I found the splice and everything looks great, maybe it's a ground elsewhere? I really need some help here as I really don't want to drop both tanks including the driver side is 3/4 full.
