If it does then something lower than that level is the source.
If it does not go lower than the needle valve inlet there is a possibility that the fuel is being siphoned back into the fuel tank.
The fix for that is to insert a one way check valve in the fuel line
The level was between the top of the power valve (shown in the picture) and the bottom of the needle valve inlet. I can also confirm it did not leak out of the float hinge pin opening.
