Nice job being curious how the sender works with the gauge. If you would have measured the resistance of the sender after you bent the full, float up tab, you would have found that you changed the full resistance! Probably about 5 or less ohms not the 10 ohms that is designed for the fuel sender. All you have accomplished is making the gauge go to full, but 1/2, 1/4 and R will not be correct! E will be close. Sadly the vendors and mfg of the Aftermarket gauge have not changed the voltage of the regulator. It needs to be at 6.4 vdc to work properly. The resistance of the sender should be: 10 ohms for F, 20 for 1/2, 33 for 1/4 45 for R and 70 for E.. Each of those numbers can be off by a bit, as you can see that 10 to 20 is for a Full to 1/2 tank... R 45 to 70 for E..
So is it not possible to fix the gauge to read halfway or did I miss something? I watch it again and I don't understand. Are you saying when the gauge reads a quarter left it is actually half tank when the foat is in the center? Thank you of creating this video, very helpful.
I love the fact that you show us how to renew the oem parts.
Another super clear explanation of why things work the way they do:) Thank you!!!

Great video! Very informative. Going through this now but with a new VDO Sending unit and an old VDO gauge in a 40-year-old VEEP kit car.
so this is what i was thinking i need to adjust my tangs becuase mine likes to be at half when its basically full
Good morning !!!

Your Beair is so cool
Question ❓ how can I install rpm meter in old car 🥺
