the silly hoses that plug into the thermostat housing running from the coolant tank there are 2 hoses one is a male one is a female.
The male hose has a teflon fiting then a oring on it, this plugs into the female fitting on the thermostat housing and thus doesnt leak.

Well I had to canibilize this oring for another ZR-1 and Now I can not find a part number for this oring.
I have looked on my parts CD no joy on the computer at the dealership nothing nada! I can not find this damn oring.

I went and purchased a set of metric orings at autozone and the largest size fits but when I install the thing doesnt make a good seal so it leaks coolant right at that fitting.
I know that the fitting is not broken it is the oring that is giving me trouble.
Doesanyone know the part number for this oring or if they can measure a known good oring and let me know the demensions I would appreciate it!
