RALZAOTO Fuel Pump Assembly for Polaris Ranger 800 (2011–2012) — Direct-Fit OE Replacement, Restores Fuel Pressure

If your Polaris Ranger XP, Crew, or 6x6 800 is showing poor throttle response, stalling, or fuel tank vibration, a worn or failing fuel pump assembly is often the culprit. The RALZAOTO 47-1012 (also referenced as 2204402, 2522139, HFP-A3963) is engineered as an OE-style replacement that bolts in in place of the original unit and is tested to meet the same functional standards. This product listing covers vehicle compatibility, installation notes, and the measurable benefits you can expect after installing the pump.

How will this fuel pump affect my Ranger's drivability?

Replacing a weakened pump restores steady fuel pressure to the engine, which improves throttle response and reduces hesitation under load. Expect a cleaner idle and fewer mid-throttle stumbles after installation when fuel delivery is consistent.

• Re-establishes factory fuel pressure for smoother acceleration.
• Reduces engine stalling and rough idle caused by fuel starvation.
• Minimizes fuel tank noise from a loose or failing assembly.
