I took it out and found there are three holes from the top and three holes from the side,
BUT one pair of holes doesn't seem to be connected.
In other words I can see how the air pipe hole connects to the bottom hole; and the reserve hole connects to the reserve entry hole; but the hole I think would be the ON does not seem connected to anything nor does the third hole from the top. In fact you might notice that hole is shiny and unused looking.
Can someone familiar with the engineering tell me if this is correctly built?
I am certain if I drilled the hole further it would connect with the hole coming from the top but that seems a rather odd thing to have to do.
