Gas gauge calibration unit

Then you should adjust the dial for the Empty setting.

One other item that I brought up earlier that should be addressed. My sending unit in the open air today in PHX, AZ was at a temp of 76 degrees. I ran the sender in the full position and am using 6.03VDC, not the 5VDC stock regulator.
Running in the open air, after 30-45 minutes the sender reached a temperature of 91 degrees. When in the car, surrounded with the gasoline, I highly doubt that it will raise the temp 1 maybe 2 degrees.
I feel this is safe enough for me in my car. You need to make your owned decision whether or not you wish to use the higher voltage if need be.

I think I need a disclaimer: I do not accept any responsibility for anyone actions, but my own. If you decide to make the modification to your vehicle as I described, you assume all the risk. I am not responsible if the 'fix' does not work or the car is damaged to any extent.
In other words; All information I have posted is for entertainment purposes only
