Re: 1954 Packard Pacific Oil pressure sending unit 4 way brass tee adapter filter/unit/gauge/block

Looks like they used an ordinary compression fitting in the tubing to supply the gauge. I think the SAE flare connections are a bit more secure such as used on the Packard block and less likely to be affected by vibration but I guess as long as it stays tight all is well. The fitting now on the engine is the Packard item. It looks like max used a regular 1/8 NPT fitting and extra nipples and adapters to duplicate the original configuration. It would be noticeable in a tight judging situation but maybe better than not having anything available.

The air cleaner with the horizontal tube is interesting. is the element end supported or is all held by the carb end? Does the horizontal tube portion serve a purpose like the horizontal part of the stock air cleaner which acted as a silencer for the rushing sound of the air flow at certain RPMs or is it more to get the element in a better or more convenient location. If the element end is not supported I would wonder if vibration could be an issue and cause mounting bolt issues with the pot metal in the carb.
