MG TD TF 1500 - Quick disconnect on oil or water meter?

Just curious if anybody has ever tried setting up a quick disconnect connector to either the oil or water meters. I don't know if anything on the market would fit, but it would be nice to be able to quickly remove those lines to work on the dash panel...

Temp gauge could present a problem as it is "gas" filled.
Oil not bad ...but can be messy if not careful.

These may be of interest for your oil meter.

They are miniature Quik Disconnect fittings.

Modern temperature gages are electric. They use a temperature sensitive resistor (Thermistor) and a meter (a current meter but one calibrated in temperature rather than amps) Quite often the Zero on the meter is offset to expand the higher section of the scale.

Conceivably you could mount a sensor and plug a meter into it when needed.

I don't know how you could mount a bulb and a thermistor together.

Positive ground would be an issue. But for a short reading now and them You could power the meter with an external battery (pack?).

David, aren't both the oil and temp lines just thin "capillary" tubes, one filled with oil and one with water? If you could fit a quick disconnect to either, how would that affect the "gas filled" temp gauge?
Still trying to gauge if this is either worthwhile OR feasible... thanks for the link JA that sounds promising...

Geoff, the oil line (tubing) contains oil (as a liquid) under the same pressure as that at which the engine is running. When the engine is stopped there is no pressure. You can undo the connector with no loss of oil.
The water temperature line is is in a different situation. The content of the line (tubing) is ether in gaseous form. It is always under pressure down to some extremely low temperature. Opening the line would result in the loss of ether. One of those laws of physics (PV=NRT) would cause you to have to recalibrate the gauge if you lose some of those moles. Hope this helps. Bud

What might work better would be to install a new more flexible line that's longer on both meters; then I could pull out the panel enough to troubleshoot etc. Currently the old brass oil line isn't long enough to allow that... maybe that's the direction I should be looking!
