I installed a voltage reducer for my gas gauge on my 48 3100. Obviously I converted to 12 volt but I have a question...

If I check the voltage at the gas gauge I am reading around 8 volts, is this OK or is this normal for the voltage reducer? It is supposed to be 6 volts but I understand that these things may not be precise and was wondering if I am good to go? I installed the one from "vintage auto garage" and it hooks right up to the back of the gauge. (looks like the runtz type)

Thanks
