Auto meter makes a good product, stay away from the cheap gauges,(glow shifts,etc). As you probably already know, it's a MUST to dampen the fuel pulsing,(with a snubber or needle valve), which kills the gauge in a hurry.
I wasn't going to say it, but I am in the exact same situation as you with my isspro gauge. I will admit that their customer support, (Michael), has been great, but I still have a gauge that I don't trust, it flutters all over. I also have never had any issues with auto meter, and I have installed MANY in customers' vehicles. My next gauge set will be purchaced soon, and will be auto meters. I just wish they made one that matches the factory gauges like isspro.My isspro has been nothing but a broken headache. Bobs up and down in the reading constantly. That's with a snubber installed, new senders, new gauge, new sender and a gauge.... Autometer gauges have never given me trouble in any of my other trucks.

Where are your sensors mounted? Do you have the latest settings in the gauge heads (Sensor Scan Rate 115, Weight 0.1)? While some VP44 trucks have been challenging with their level of fuel supply pulsations, I am sure we can get yours working smoothly.I wasn't going to say it, but I am in the exact same situation as you with my isspro gauge.

... any mechanical gauge like Autometer, ISSPro, etc. Good high quality mechanical gauge with a needle valve will out live any electric sender gauge plus keep its accuracy much longer.ISSPRO all the way. Correctly installed with needle valve and you are golden.
