I will show how I took the stock fuel sender and float and put it in a fixed vise and made a chart behind the float to mark the upper and lower float level positions. And then I will give out the part number for a new Olds sender unit that can be removed from the tube assembly and fixed onto the SC assembly in place of the SC sender.

Float/sender assembly: FG09A -and can be had on egay for under $50 delivered

I will then show how to bend the float arm of the newly grafted Olds sender to make the minimum and maximum positions line up to exactly the same positions of the original SC float.

I will show how and where to install the Olds oil pressure sender and how to adapt the plug to the SC harness. I will show how to do the same with the temp sender.

Then I will explain how to install the DD tach calibrator for the 1UZ guys/gals. The JZ guys/gals may not have to use a calibrator since the Olds is already a 6 cylinder.

Then I will explain how to install the DD speedo calibrator and how to do the calibration. It might be a bit of work to do -but I will make it easy to understand.

Roll Tide!!
