Will the correct gauges ever be placed in both the F6F-3 and F6F-5 as related to Oil-In Temperature; fuel tank levels and remaining water level for water injection?

There should be no coolant gauge (as currently labelled) under the Cylinder Head temperature gauge.
This should be the oil-in temperature gauge.

The bottom right gauge should be fuel level only (3 needles) indicating fuel capacity of the three fuel tanks.
This gauge is larger and easily read. It should not a combination gauge of one fuel tank, oil pressure and oil.

There should also be a water quantity gauge for the A.D.I system (water in the tank for water injection).
This is located to the right of the main control panel.

My reference is the photographs and associated legend/list inside of the Pilot Operating Instructions for the F6F-3 and F6F-5 Airplanes. I have attached a .jpg file with photo and legend.

Thanks in advance.
