I have a 2000 polaris xc 500 and dont know where the premium fuel switch is. I looked in the manual!

Don't know for sure if your model ahas it, I know mine does...its an option where you turn the key to, one for premium and one for regular

It only has a 2 position key, so i am digging around for it.

You don't have a switch to select the fuel octane. I just researched and bought my sled and learned the octane selector is not on the 500 XC. It functions with the Throtle Position Sensor (TPS), don't think your sled has this.
