Default Oil guage - copper or plastic ??

I have to replace the oil guage line. I purchased the replacement plastic line but I also have a roll of 1/8 copper tube. Would it be better to use the copper line with the new compression fittings or stick with the plastic as supplied?

NO, NO DON'T use the copper! It fatigues much too easily and WILL crack and puke all over things!

Plastic is better, best is a S/S braided line. Summit carries them.

FYI: My 70' has what appears to be a copper oil gauge line. I will check with a magnet to see if it copper coated steel.

James,

The thread is C2 but the info is relevant to C3 manual oil gauges as well.

Thanks Paul. I've had my 70' since 87' and the copper (?) oil line has never caused me a problem. After reading that link, I'm definately going to check it out with a magnet when I get home. As I've just purchased a new oil gauge (previous gauge stopped working and I'm now wondering if maybe the line is at fault and not the gauge (?). I have confirmed oil flow when the engine is turned over so assume my old gauge was at fault). Anyway, I have yet to hook-up the new oil gauge to verify operation.

Finally, I've noticed that some oil gauge lines (and replacements) are plastic and thus assumed the copper (?) line on mine was original.

The education never stops on CF!

Thanks again Paul.

James

I had the plastic one fail and leak oil all over my radio. I installed a copper line and insulated the outside with heat shrink. You have to be careful when running the line behind the other gauges. If you position it incorrectly, it can short out across other gauges inputs. To help with this I used shrink wrap on the tube all the way to the dash. It has worked with no issues for three years now.

James, I'm bought and am picking up a 71 350/270 Thursday. The oil pressure gauge does not indicate, such as yours. What would you recommend to verify oil pressure and flow long enough for me to get home. I'm driving it 3.5 hours home and need peace of mind. Any help appreciated. Thanks, Jeff
