EVP High-Pressure Fuel Pump w/ Surge Tank Kits for Polaris RZR Pro XP, Turbo R & XP Turbo/S

EVP DISCLAIMER: The above specs are for the NON-FPCM systems (Fuel Pump Control Module). The Polaris FPCM will vary the voltage of the pump to maintain an ECU-specified fuel pressure. Due to the variable voltage, the performance of the pump is somewhat less than a direct 12VDC system. That is why the return-style fuel systems have a higher horsepower fuel flow rating. The internal pressure relief valve setting is 100PSI.

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 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.

A surge tank is a small fuel tank within the main tank that provides a reserve of fuel so that when the fuel is sloshing around in the tank, the pump always has a supply from the surge tank to draw from. The preassembled EVP surge tank systems (Stage 1 & 2) feature an integrated E85-safe 340LPH fuel pump to deliver big-power fuel volume while still being versatile enough to enhance fuel delivery on stock power levels down to the last gallon of fuel. In most cases, no tuning changes are required regardless of the tune being run. (Minor tuning changes may be required on some models.) Additionally, all internal componentry has been improved with EVP-designed custom Venturi jets and premium hoses to properly feed the surge tank for more consistent fuel delivery. With the introduction of the all-new Stage 2 Rising Rate High-Pressure Fuel Pump w/ Surge Tank Kit, EVP now has two proven solutions that provide the ultimate safeguard against engine starvation regardless of how much fuel is in the tank.
