For anyone who has done an engine swap and used the Mini fuel tank, how have you dealt with the fact that the Mini level sender range is ~30-290 Ohms, and most modern cars are something like 5-105 Ohms. How have did you get the Honda/Toyota/Daihatsu etc fuel level gauge to calibrate/work with the Mini sender?

Alan, I have a PCB mounted on my fuel sender which has resistors on it that could be changed to any values you wanted! I chose to make a PCB when the arm had worn through the wires in the sender. It isn't perfectly analog but does have 23 steps from full to empty! :D

You can get converter boxes like this

I also vaguely remember Howard’s instruments were able to adjust the sender to match any gauge (and probably vice versa)

These guys are familiar with Minis and do a converter https://www.spiyda.com/fuel-gauge-wizard-mk3.html

I've done two methods with success:
1. Spiyda converter as noted above, and
2. Remove mini sender, and replace with an aftermarket one that is a standard 0-90ohms. This method really only works on injected tanks though as you need to use the pump access hole in the top to work out what arm length you need to setup in the tank.
