Put all new gauges in so I wanted to make sure they worked. The 10 gallons gave me a base line to go from. Looks like tank is 22 gallons. Now I have to see about setting up the speedo. I was going to use a turbo 400 but decided on a 700r4 which of course I had to buy an additional sensor for the speedo to read the tranny pulses. Again I will set some kind of a base line so I have a place to go back to if I get into trouble. No tune up needed. It's a learning curve. Just a little something us old guys have learned over the years eh.
