12-Volt Negative Ground Fuel Gauge

Specifications 0 - 30 ohms resistance 12 volt negative ground Black face, white lettering Other Application Info Our custom fuel gauge is only for tractors that have been converted to negative ground. The factory electrical system was positive ground. For positive ground systems please use JDS1707. Use with our original style sending unit, JDS1712. For maximum performance, it is always best to order the fuel sending unit and the matching fuel gauge as they will have the correct Ohms and voltage. Gauge must be grounded to work properly; in some cases you may have to run an extra ground wire from the threaded clamp terminal to an existing bolt to get a proper ground. If you have any questions, then please open the instruction tab for both video installation and written instructions.
