GMT 3500 purchased recently. At times fuel gauge jumps back & forth slightly. When this happens motor starts missing pretty bad. Last about minute or two usually, then starts running fine, maybe for rest of day. Thanks

Corroded or missing ground connections. Ground cable from battery, ground strap to the engine and any other ground around the truck. Look there first.
