19 With everything ready, we hit the key and the gauges acted like a new car and ran up, then came down to zero. Since the fuel gauge is made for our sender's ohm rating it reads a little over a quarter-tank, which is what it should be since we put in six gallons of gas in the 20-gallon tank. We fired up the motor and the rest of the gauges came to life. The last thing we needed to do was set the speedo per the instructions, which is basically put the gauge in set up mode and then drive a marked two miles. After that we just sat and stared at how cool all our new stuff looks, and you can tell by the lead image thing get even better at night.
