At least on the m20 models there is.
One sending unit is attached to the fuel pump as in the earlier models, the other one is on the other side of the fuel tank. If you remove the seat to access the fuel pump there is another access panel on the other side.
I can't remember which one controls the light and which one is the gauge.
