Mechanical Oil Pressure Gauge
When fitting a Gauge to the A-series, you should know that the oil pressure switch threads are 1/8 BSPT (british standard pipe tapered). It screws directly into the oil pump housing.
CAUTION: Many gauge kits use Standard threads. Use an adapter fitting.
If you instead use a Tee connector, you can fit both the sensor and a separate gauage. Tees are avaialable in the usual auto supply stores such as Repco or Oreilly's.
Tee fitted to oil pump [Old Method, no longer recommended]
Right: this engine has the Tee (and an oil cooler)
New Method
A word of caution with this: they tend to break, perhaps due the weight of the sender at the end of the tee piece and the vibration of the engine. The solution is to use a braided hose from the oil sender hole out to the bodywork, and then mounted the tee with senders in place.
Datsun Nationals 2005 .. I think 3 different cars had their brass t-piece fail resulting in oil all over wakefield track. Definitely mount the brass fitting on the bodywork, not the engine. dattodude
