Hello, i have a 1997 Ford Ranger XLT. My gas gauge wasn't working properly, like: when i filled up the tank it would go all the way up, but ones it gets down to a quarter it stays there. So I took the bed off and replaced the sending unit in the tank. the problem persists. I also found out that my temperature gauge isn't working properly either. And temp. and gas gauges are on the same unit. My question is that if i can replace the entire dashboard? but my original doesn't have RPMs on it the new one i saw at the junkyard does. So will the rpms work?and is it a good idea to replace the entire thing? or is there another alternative?

You might have a bad ground in the engine bay that is causing backgrounding in the dash. I have seen it happen before. It can cause turn signals to stay on dimly, gauges malfunction, etc.
I am attaching ground point diagrams for you to check . Make sure they have tight metal to metal corrosion free fit.
