I don't want to correct anyone, but this isn't right. In the directions, it states that you set the rotary dial to 7 when using the Mopar style mechanical IVR. I just installed a Meter Match in my Dart, after looking for years for a stock sender, including posting a want ad on here. My aftermarket sender was either full, or empty. It was $65. Not bad compared to the cost of a rebuilt. Wiring is 4 wires. I set mine starting with an empty tank. used gas cans to measure the amount put in to set the 4 positions on the Meter Match. I don't know if it works well yet, as I just installed it, and haven't driven it.
