Oops! I can't attach the cropped photo as it gives an Protector detects attacking actions error.

Don, If the cropped photo that had the problem has a title like Apple normally puts on their full or partial screen captures it could be that the time numerals separated by periods are causing the protect issue and need to be edited out. The site sees the title as a stand alone element and the number and dots string as an IP address that might be trying to hijack the post. For example, if this was a photo title it would fail Screen Shot 2014-08-23 at 4.43.35 PM.jpg and this one would not Screen Shot 2014-08-23.jpg.

On the Fram filter you will need to determine which port is inlet and which is outlet. Some Frams such as those Packard used prewar had the inlet on the bottom with a flow restricting orifice in one of the brass fittings on the tubing going to the inlet side to limit flow to roughly 10% of the total available at the bottom port. The filter element should have a center opening that is sized to be snug to the pipe and bottom would sit on large washer like base near the bottom of the pipe. There would also be another washer on the end of a spring attached to the cap to seal the top of the filter and allow for different lengths. The spring also keeps the element pushed tight on the bottom seat. That snug center opening in the element and the top and bottom washers is what prevents the flow from bypassing the element. Oil enters the pipe, flows out to enter the element at the center and flows thru collecting around the outside of the filter then out to the engine. With that flow direction the small center area could clog quickly so some of the prewar filters for the 356 engine had a relief valve at the top of the pipe what would open if the filter clogged. The oil could escape the pipe and flow over the top of the element and back out. That style was not in use very long before Packard changed the plumbing and return flow back into the engine and eliminated the valve.

The black one with the small holes in the center pipe is probably postwar and correct for the car. On the postwar canisters, the function is about the same but inlet is on the side. Oil enters and surrounds the filter element then passes thru to the center pipe and back to the engine. Those filter element centers are also snug to the pipe and has the washer like base and spring top. For the postwar filters the supply side orifice in the fitting was eliminated and the small holes in the pipe are sized to provide the flow restricting orifice. They also ensure only a limited amount of oil (again approx 10%) can pass thru the filter and get out. Dirt and sediment fall to the outside of the element and because the washer the element sits on does not reach all the way to the sides it can collect at the bottom of the canister around the pipe.
