Autometer gauge Qs

[Mr. Sphincter]

I want to put autometer guages (unless you can suggest a better brand) in my dash i am going to fab up. I want a Speedo, tach, oil pressure, fuel, and temp, and volts. I know the speedo is mech and my tach is elec, but what are the others? Also for the fuel gauge what ohm range do i want, the 73Ωs Empty / 8-12Ωs Full, 0Ωs Empty / 90Ωs Full, 240Ωs Empty / 33Ωs Full?

Thanks
Mike
