2005-07 Sportsman 800 Fuel Pressure Regulator
Having running or fuel issues with your 800 EFI? In many cases the fuel pressure regulator is the culprit. Installs in the stock location just like the OEM unit and keeps your fuel pressure at a constant 38-40 PSI. Polaris does not provide part numbers to cross reference the fitments. For that reason please remove your stock regulator and compare to the photos carefully before ordering. Its possible your 2005-2007 Sportsman 800 EFI could actually use our part number 100-3091 instead of this 100-1100.
