OK. Since I've made such an effort to isolate the cockpit from the engine compartment, the thought of running a pressurized oil line to run an oil pressure guage into said cockpit leaves me cold. Would I be better off with an electric guage? Wayno
Just tie a rag around your leg under the gauge. oh , hang on, wrong car.
Put a gauge down the back somewhere so you can look at it when you are tuning it. Just a red light in the front for oil with a high pressure (more than 10 psi) switch, and a different color shift light, and a tacho. Doesn't matter where you put the tacho as you will not be able to see it
If you see a red light come on, switch the motor off and turn out, if you see the other color light, change gear.
