Reply to "Tach and fuel guage stopped working......?"

Check your fuel sensor (get a wiring diagram)on mine bk/white stripe is the gas gauge needle 0 ohms is full 200+ ohms is empty unplug the wire and ground it to a good ground and look at the fuel gauge if the needle moves the meter is good and so is the wiring to it.

Next pull the sending unit out (Jack is right pulling the quarter window is the best way but) on my 74 #6656 you can get the unit out of the gas tank if you do it carefully.

On mine the sending unit float sank (Bennet Auto Supply $19 universal fit Sunpro Gas sending unit float is very close if you want one now), the vendors sell the correct float. I have no idea about the tach and why both would quit at the same time. I will look at my diagram and if I see something I will reply again... good luck
