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

Thank you Howard. Great info on the bracket issue. Regarding the engine oil sending unit, I received a new adapter and new unit/switch. The new switch does not screw all the way into the adapter. The old switch does appear to screw all the way in the original adapter though. The issue appears to be common on the internet for modern cars. (TAPERED) 1/8th NPT vs BSPT vs straight thread adapter. Is it ok to screw in just to as far as it goes with teflon tape or is it necessary that the switch screws all the way into the adapter?
