Hi everyone, I have recently got 3 gauges, oil temp, oil pressure and voltage, the oil temp has a probe that goes into the custom sandwich plate and is connected electrically to the back of the gauge. The Voltage gauge is amazingly connected to the live and earth, but the oil pressure gauge uses a long pipe that goes to the back of the gauge off the sandwich plate.

This means that boiling oil under 60+psi of pressure is being pumped into the car, is there any way I can convert this to run electronically?

I know that the heater matrix pumps boiling hot water into the car and im not worried about that, the gauges have come out of a car where this setup was working fine and the end fitments look chunky (not ebay rubbish).

Would it be safe to install the oil pressure gauge? Maybe I could wrap some of that plumbing PTFE tape round the threads as well?

The only way is to replace the mechanical gauge with an electrical gauge.

It\'ll be fine though, loads of people use them. I\'m guessing there\'s some microbore tubing and a brass olive to seal it? It\'ll be grand :)

I must admit I\'d prefer electronic sender any day, unless it\'s vac line.
 
But as long as you don\'t pinch off the tube, and make sure when you pass it through the bulkhead you use a grommet around it - so it won\'t snag or chaif you should be fine

Not a big problem with this matey!! all the old Mini\'s, Jags, Astons, etc use a capilary type gauge!! to be honest with you, you will have a more acurate reading from this than an electrical one as it reacts inediatly!

My mini only has a single centre gauge showing speed and fuel, none of these new fangled fancy temperature or pressure gauges for me :rollin

I think it will be ok, I deliberatly got a mechanical boost gauge as I don\'t like to use those \'autogauge\' style electrical one as first the sender has to send the signal for the stepper motor to then react to, instead of the actual thing you are measuring affecting the gauge directly so im all for mechanical gauges, just needed to check it would be ok :)
