If your Polaris Predator 500 or Outlaw 500 ATV is running poorly, bogging down, or having fuel delivery issues, this little diaphragm might be the culprit. This is the genuine Polaris part (number 3131479), and it's a critical piece inside the carburetor or the fuel pump (depending on the model). Over time, these flexible diaphragms can crack, stiffen, or tear, which messes up the fuel metering. Replacing it is often a much cheaper fix than a whole new carburetor. This part fits the Polaris Predator 500 from 2003 to 2007, the Predator 500 Limited from 2004-2007, and the Outlaw 500 2x4 from 2006-2007. Always a good idea to check your service manual to confirm this is the right part for your specific machine and to see exactly where it goes. A simple, affordable part that can bring your ATV back to life.
