I bought an aftermarket set of guages to mount under the dash. They are the Sunpro 3 pod guage cluster with oil pressure, water temp and volts. I have the temp and volts hooked up but here's my question. I've heard horror stories about the plastic hose that's used to connect the oil pressure guage to the engine breaking and causing oil to leak into the interior or engine compartment. How big of a concern would this be and do any of you have other methods of connecting this guage (steel or copper lines)? Maybe I'm just being over cautious, but any input would be greatly appreciated. Thanks! Bill

Going to a metal tube is a good idea.

One can go to a refrigeration parts place or a hydraulic hose retailer and pick up either 1/8 inch copper tubing or steel tubing. Copper tubing has a much smaller ID than steel causing the gauge to react very slow.

Summit does sell an oil line kit of stainless steel braided tubing in three lengths, 3', 4', 6'.

Copper tubing isn't a good idea to use for this application - it's subjected to vibration, which will work-harden the copper and it will eventually crack. The older OEM Corvette applications used what LOOKS like copper tubing, but it isn't - it's copper-plated STEEL tubing, just for that reason. The plastic (nylon) tubing will work just fine, as long as it's routed so it doesn't rub on anything sharp and you use a rubber grommet where it passes through the firewall.

I've had no problems with the plastic tubing. If I ever change gauges, I will go with the electric instead.

I bought an Autometer copper tube for $10. came with all necessary fittings and firewall grommet. Is this a bad kit?
