Our review of the 47-1012 fuel pump assembly finds it best suited for owners of 2011-2012 Polaris Ranger 800 models who need a direct-fit replacement with OEM-like performance. The pump delivers consistent high-pressure flow thanks to an updated internal turbo design, translating to good engine power and acceptable emissions compliance for this application. It is straightforward to install for anyone comfortable with basic fuel-sender work, and it is a practical, cost-conscious choice when the original unit fails or leaks.

Key Features

• Replaces OEM numbers: Direct replacement for 47-1012, 2522139 and HFP-A3963 so users can match part numbers for correct fitment.
• Improved flow design: Equipped with a technical turbo that helps maintain higher, more precise fuel pressure for consistent engine performance.
• Model fitment: Built to fit several Polaris Ranger 800 variants from 2011 and 2012, reducing search time for compatible units.
• Physical size note: The assembly measures 16.1 in overall, which is important to confirm against the vehicle before installation.

Who It's For

This pump is aimed at DIY owners and mechanics who maintain 2011 and 2012 Polaris Ranger 800 machines and need a straightforward replacement that closely matches OEM function and fit. It is useful when the original pump has failed, shows low pressure, or has begun leaking.

It is not for riders of unrelated models or years outside the specified list, and buyers who require long-term proven high-mileage durability for heavy commercial use should weigh the mixed durability reports before deciding.
