EVP High-Flow Fuel Pump Assembly with 340LPH Fuel Pump for 2017+ Can Am Maverick X3

The EVP Maverick X3 OEM High-Flow Fuel Pump Assembly is the industry’s first complete, drop-in replacement designed specifically for high-horsepower builds. Featuring an integrated 340LPH pump, this assembly eliminates the need for tedious modifications to the factory unit, providing a reliable and "off-the-shelf" solution for fuel-starved engines.

This kit is essential for any Maverick X3 exceeding 250 HP and is a premier upgrade path for 120HP base models transitioning to big turbo systems like the EVP Paragon or DS-395.

Key Performance Features

• True Drop-In Convenience: Ships fully assembled with the 340LPH pump, pickup, float, fuel hat, filter, and a 65 PSI regulator.

• High-Power Capability: Engineered to provide proper fuel flow for systems ranging from 250 HP up to the 395 HP (DS-395) mark.

• OEM Compatibility: Designed for a perfect fit with both factory and EVP 14.3-gallon X3 fuel tanks.

• Reliability: Replaces aging or underperforming factory pumps with a high-capacity unit capable of maintaining consistent pressure under extreme demand.

Fitment and Requirements

• Tuning: ECU recalibration is required to accommodate the increased fuel flow and pressure.

• Relay Harness Requirement: An EVP Fuel Pump Relay Harness is mandatory for the following models to ensure stable voltage delivery:

  • 2017–2021 X3 Turbo R

  • 2018–2022 X3 Turbo

  • 2020 X3 Turbo RR

Technical Note: If you are upgrading from a 120HP base model, this pump provides the necessary overhead for future turbo upgrades without needing to pull the tank a second time.
