Problem with instrument panel

[reblawyer]

I have lost my rpm readout and my fuel readout. They were working when I first got the truck but have since given out on me. Voltage, air pressure, oil pressure and speedometer all still work. Any thoughts?

2 different problems. RPM is probably a bad cable (or the cable came unhooked). fuel gauge is probably a bad connection at the sending unit?
