The Polaris Ranger 800 XP 4x4 is built for the kind of work and terrain that would stop lesser machines — ranch trails, muddy fields, steep hillsides, and everything in between. When the fuel pump starts to fail, you get the symptoms that no Ranger owner wants to see in the backcountry or mid-job: hard starts, sputtering under load, and the fuel starvation that kills power right when you need it most. This complete 40cm fuel pump assembly (F01R00S356 / 2521322-A) replaces the entire pump unit — motor, impeller, and pressure regulator — restoring factory fuel pressure and flow for reliable operation wherever you take your Ranger.
Your Ranger goes everywhere — make sure the fuel pump keeps up. Order today, in stock and ready to ship.
