Just got back from the speedometer shop and had the fuel gauge checked out. Turns out the gauge is working great at 6 volts but to jumpy/sensitive when tested at 12 volts. I brought along the Runtz reducer I had on the gauge and it tested bad. I had a second Runtz I brought along, that I already thought was bad, and it also tested bad. Now I'm on the hunt for a good reliable reducer. One suggestion by the shop is to use a 1973 Dodge van instrument cluster reducer from Napa, about 40-50 bucks. They were not to keen on the Runtz reducers and neither am I at this point. Said Runtz have a bad track record.
