I also have a MF135 and have had to replace the original mechanical voltage regulator with an electronic one. The mechanical regulator had a resistor on the 4th terminal that cut the voltage to approximately 4 volts for the fuel gauge. You cannot just hook the fuel gauge to 12 volts as it will peg the gauge.

The potentiometer is way cheaper.

The front end center pin bushing was worn also so I ask that they replace it if they had time. Well, that’s wha
