91 Wrangler gauge cluster and fuel tank

Hello, I have a 91 wrangler, 6cyl. With about 150,000 mi. On it, the gauge cluster quit working all of a sudden, the rpm, temp, oil press, fuel, battery, none of those are working now, the speedo and clock still work, I have pulled and visually checked every fuse on the vehicle they all appear to be good. I dont know what else to check. It was working fine and then on a kind of rainy day I cranked it up and the gauges quit working. I just put a new ignition and key assembly in right before this happened but it was working fine after I got done. Got any ideas what it may be? I also have one more question, I am haveing trouble putting gas in the vehicle, it seems every time I go to fill up I have to run the pump at a very low volume to keep it from backflowing and shutting the pump off, I checked the filler neck and vent hose for kinks but they are fine.?
