Joe,

A couple of things to note:

The 1948-50 Custom 8's did away with the pressure regulating piston in the oil gallery and used a restriction in the tee that feeds the gallery to limit flow and prevent over oiling of the timing chain. A similar restriction was used for the feed to the oil filter. These restrictions were built into a single 4 way tee that was fed from the main oil gallery, so one restriction on each side of the tee with none on the feed and pressure sender connections.

The 1948-50 oil filter inlet is the upper one on the side of the cannister. The filter outlet on the bottom of the cannister drained into the crankcase. This is opposite from the 1940 filter, so you may want to re-check the flow arrangements to match the filter that you have used.
