GOLKNHA Fuel Pump Retaining Nut Tool for Polaris 500–1000 EFI — Hardened Steel, 3/8" Drive

The GOLKNHA Fuel Pump Retaining Nut Install Removal Tool is a heavy-duty specialty socket designed to remove and install the fuel pump retaining nut on many Polaris Sportsman, Ranger, RZR and Scrambler EFI models.

This purpose-built tool fits the unique retaining-nut profile used by multiple Polaris ATVs and UTVs, letting a technician or DIYer service fuel pumps without damaging the nut or tank. Machined from hardened steel and finished with a corrosion-resistant spray coating, it accepts a 3/8" ratchet adapter or breaker bar for controlled torque. The tool is compact, durable and made to slot directly into the injector-access opening for faster, safer pump work.
