In-tank EFI pump assembly for Polaris RZR

This Quantum HFP-A3964 replaces the original in-tank electric fuel pump on Polaris RZR 1000 XP and MUD models from 2014 to 2020. It also fits the RZR 900, XP and 4 variants built between 2015 and 2020, plus the Sportsman 1000 produced from 2017 to 2020. The transparent housing lets you visually inspect the module before installation.

Vehicle fitment is the only specification

The pump assembly carries part number 3964 and is engineered for the exact fuel-system pressures and electrical connectors used on the listed Polaris models. No flow-rate, pressure or voltage figures are published, so matching the year range and model name is the sole method to verify the part will work.

Direct OEM-style replacement simplifies the swap

Because the unit includes the complete sender assembly, the fuel tank does not need to be modified or drilled during installation. The most common issue is forgetting to relieve fuel-system pressure before opening the tank, which can spray fuel and damage the new pump’s internal filter.
