Vehicle Fitment

The Quantum WAL-PPN27 is an in-tank EFI fuel pump built as a direct OEM replacement for Arctic Cat ATVs. It fits 450 Alterra XC models from 2015 to 2020, 500 XR from 2015, 550 Alterra from 2016, 550 XR and XT from 2015, 700 XR and XT from 2015, Alterra 500 from 2016 to 2020, and Alterra 700 XT EPS from 2016 to 2020.

Fuel Delivery Operation

The pump mounts inside the fuel tank and supplies pressurised fuel to the electronic injection system. Its transparent housing allows visual inspection of the internal components during installation or service. Normal operation delivers consistent flow without the mechanical noise associated with external pumps, drawing power directly from the vehicle electrical system.

Replacement Scope

This unit replaces a failed or worn factory pump on the listed Arctic Cat models when fuel pressure drops or the engine struggles to start. It restores original fuel delivery performance for the specified 450, 500, 550 and 700 displacement engines across the 2015 to 2020 model years. The pump does not add capacity beyond the OEM specification.

Questions about this item

How do I install the Quantum WAL-PPN27 in-tank EFI fuel pump and what step do people often miss?

Install by lowering the pump into the fuel tank and securing the retaining ring; the step often missed is seating the new seal fully so the pump stays pressurised.

What maintenance or replacement will the Quantum WAL-PPN27 fuel pump need later?

Replace the pump if fuel pressure drops or the engine hesitates; the in-tank filter screen should be inspected whenever the tank is opened.

What limit shows up first on the Quantum WAL-PPN27 fuel pump under sustained use?

The pump can overheat if the fuel level runs low, because it relies on surrounding fuel for cooling during extended operation.
