Oil Pressure Gauge for 3.0

[Grant Iddon]

Whilst my Blackstone engine (and transmission) oil test reports show good (low) wear with no high values even after 160k km, I'll be doing some long range cruising so contemplating an engine oil pressure gauge.
Location fit and brand advice most welcome if anyone has done this?
cheers

Insert a T under the pressure switch with appropriate thread for the pressure sensor. You might want to replace the original tall pressure switch with the short version LR000633 so that the pressure switch lead still reaches and to reduce the possibility of knocking the sensor which would otherwise protrude well above the surrounding parts.
Use a 0-100 psi sender rather than 0-150 psi as whilst the cold pressure gets to around 65 psi before the pressure relief valve opens, the gauge needs to be able to show under 10 psi. Hot idle should be 12 psi but supposedly acceptable (but IMO questionable) down to 8 psi.

I initially used a small round electronic 0-100 psi gauge on my 4.4 TDV8 but the gauge was too small and hard to read to be very useful so I built/programmed my own digital gauge, using the sender's volt/pressure specs.

Edit: This one with digits would be more useful than one with just a dial.

The sensor on the next one is too big.
