Scott Swartz added one to his dry sump tank. I bought parts from McMaster Carr for my coolant recovery tank and expansion tank.
Question here.
could you not just utilise clear tube ( rated for the suitable heat and pressure) for the top feed into the expansion tank?
That would show the level of the fluid without having to modify the tank?

I only use a sight tube on my expansion tank. As long as your radiator cap is working properly that’s really all that’s needed. If you lose enough fluid that the primary tank is low that’s usually an obvious leak or overheating situation.

I believe the main tank is 2 quarts and the overflow is 1.5.......its been awhile since I had them made. The level in the overflow fluctuates about 2 inches hot to cold. I run it 1 inch above the lower fitting when cold.
Frank the body is relieved above the cap and although it is
tight the cap does come off and access to fill it is good.
