When the oil pump is removed should a visible path be seen between the oil pump side and the other side where the line goes to the oil tank?

A person rebuilt this motor and the oil hasnt work since. It appears to have a mechanical blockage in the oil channel, perhaps a gasket face or another metalic item. Anybody tear down a bike a recall this area?
