Quantum HFP-396-U4F In-Tank EFI Fuel Pump with Regulator and Filter

Exact-fit replacement for Polaris EFI models

This in-tank electric fuel pump replaces the original unit on a wide range of Polaris utility and sport vehicles from 2011 through 2020. It covers Ranger, RZR, Sportsman and Scrambler models with displacements including 500, 570, 800, 850, 900 and 1000. The assembly arrives as a complete module with an integrated pressure regulator and filter. No separate components are required for installation.

Steady delivery under continuous operation

The pump maintains consistent fuel pressure throughout extended riding sessions and heavy throttle use. Its built-in regulator keeps the fuel system within factory specifications without fluctuation. The included filter protects the injectors from debris that can accumulate during long service intervals. The transparent housing allows a quick visual check of fuel condition before each ride.

Direct drop-in with common pitfalls noted

Installation follows the factory procedure: remove the tank, swap the module and reconnect the electrical plug and fuel line. The most frequent issue is forgetting to relieve system pressure before opening the tank, which causes fuel spray. Another common mistake is reusing the old sealing ring instead of the new one supplied with the kit, leading to vapour leaks. Ensure the float arm moves freely before reassembly.
