Mexico built sender and AM gauge 5 1 regulator/stabilizer, how well do they work together?

Update 3/10/2022 I do not recommend modifying the regulator to 7.5v and then calibrating the gauge. see my buck regulator videos.
How well the 3 devices work together right out of the box. No modifications.
Mexico Sender, aftermarket gauge that has not been calibrated and a 5.1volt regulator "stabilizer".
This shows the discrepancy of the aftermarket fuel gauge that has 34ohms resistance and the stock non-oem regulator/stabilizer.
