Did the D19 gas originally come with a six volt system? If so then it would be a positive ground. Am I correct in making that assumption? Also has anyone ever experienced problems with the fuel pump on these tractors!

Any A-C with a generator (from the Factory) was a POSITIVE ground. Makes no difference 6 volts or 12 volts. All D-19's were 12 volts. Fuel pumps go bad and I don't know if any parts are available from AGCO. Pretty sure it's an AC Delco pump.
