The ultimate answer to fuel-starved RZR's is finally here!
EVP's Jim Zuccone breaks down why fuel starvation to the engine (leading to misfires) is a major problem that plagues all Polaris 2016-2021 XP Turbo and 2020 Pro XP platforms due to the lack of an integrated surge tank as part of the fuel system. These vehicles utilize a rectangular fuel tank design with a single strainer-style fuel pickup. The issue is when there’s less than 4 gallons in the tank. Under acceleration, deceleration, bumps or long sustained turns, the fuel moves away from the pickup and causes misfire and/or lean conditions. Four gallons is more than 1/3 of a tank of fuel that cannot be used reliably due to these issues. In 2021, Polaris added their own design surge tank, but with an undersized fuel pump that does not support enough fuel flow for any power level beyond what can be achieved with the stock turbo.
The EVP High-Volume Fuel Pump & Surge Tank Kit is a direct replacement for the OEM fuel pump (the factory fuel hat and float are reused) to safeguard against engine starvation regardless of how much fuel is in the tank.
