Fuel gauge + guage lighting

fuel gauge is on E … and ive put atleast a half tank of gas in … the temp gauge and speedo are working fine … the gauge lighting is out. Will i have to buy a new cluster or can this problem be fixed … about the lighting im sure the bulbs are burnt out , will 194’s fit ?

Edit: its a 1990 240sx
