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

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

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.

(NEW) STAGE 2 High-Pressure Rising Rate Fuel Pump w/ Surge Tank Kit
For maximum fuel flow and delivery, the new EVP Stage 2 Rising Rate High-Pressure Surge Tank Kit checks all the boxes. This direct replacement for the OEM fuel pump assembly (factory float module is reused) features an integrated 4 BAR fuel regulator to increase fuel pressure on demand to the 340LPH pump for crisp, instantaneous acceleration. Additionally, this updated version of our original RZR Surge Tank design features an integrated billet fuel hat that connects to the factory fuel line in place of the OEM plastic hat. Only the OEM float is reused for a near-direct replacement drop-in kit that makes installation much easier compared to the EVP Stage 1 kit.

• NOTE(s): Stage 2 Surge Tank Kits are compatible with all RZR Pro XP & Turbo R models, and 2019-'21 XP Turbo/S models WITH FUEL PUMP CONTROL MODULE (FPCM) only.
• Requires EVP or aftermarket silicone charge tube to run the vacuum line for the rising-rate system.

STAGE 1 High-Pressure Fuel Pump w/ Surge Tank Kit

The Stage 1 High-Pressure Fuel Pump & Surge Tank Kit features the same internals as the Stage 2 kit, minus the 4 BAR regulator and billet fuel hat (the factory fuel hat and float are reused for all Stage 1 Surge Tank kits).

• NOTE: Stage 1 Surge Tank Kits are compatible with all RZR Pro XP & Turbo R models, and 2016-'21 XP Turbo/S models with or without the Fuel Pump Control Module.

EVP has worked with racers who attest to the surge tank's effectiveness. In their own words: 'With the OEM fuel system, I was not able to run with less than 3 bars on the gauge without fuel starvation issues. Now I can run down to the last gallon and the engine never misses a beat.'

FEATURES:

• Enough fuel flow for 300 crank horsepower on E85 (19-21 XPT, All Pro XP and Turbo R returnless fuel systems) and 400 crank horsepower on E85 (16-20 XPT return style fuel systems)
• Completely designed in-house and thoroughly tested on both stock and high-horsepower cars
• Eliminates engine fuel starvation caused by fuel 'sloshing around' in the tank once levels get below approximately four gallons
• Integrated 340LPH fuel pump and EVP-designed Venturi-style fuel pickup system with premium hoses for consistent fuel delivery regardless of levels
• Significantly improved fuel delivery upon launch/acceleration, navigating elevation changes in the dunes, as well as short-course or other racing situations
