Sabb Model G - Top end lubrication

[mcamir]

The top end of my Sabb Model G is drip-lubricated by a wick leading from a small cup located on the valve cover. The cup drips into this sort of distributor block underneath the valve cover. The manual is unclear whether there should be a wick leading to each endpoint of copper tubing that is plumbed into the distributor block, or if there is just one short wick leading to the distributor block itself. Can anyone help?
