Lamborghini Urus FX-350 Upgraded High Pressure Fuel Pump System

Spool Performance FX-350 High-Pressure Fuel Pump Upgrade for Lamborghini Urus

What is the FX-350?

The FX-350 is an upgraded mechanical high-pressure fuel pump designed to significantly enhance the performance of your Lamborghini Urus. Featuring a larger bore size than the stock pump, the FX-350 delivers approximately 90% more fuel flow, making it ideal for performance tuning. Fully E85 compatible and plug-and-play, the FX-350 requires no cutting or splicing during installation. The increased fuel flow allows for higher ethanol concentrations and supports larger turbo setups, making it the perfect upgrade for those looking to push their Urus to new performance heights. Additionally, the FX-350 can operate at pressures up to 350 bar, increasing injector output and reducing injection times for maximum efficiency.

The Spool Performance FX-350 sets a new benchmark in fuel system technology, delivering superior pressure and atomization for Lamborghini Urus owners looking to achieve top-tier performance.

Why Upgrade?

The stock high-pressure fuel pump in your Lamborghini Urus can restrict performance when tuning for higher power outputs. The FX-350 delivers 90% more fuel flow, enabling you to safely increase horsepower, accommodate larger turbos, and use higher ethanol blends. This upgrade is essential for performance enthusiasts looking to unlock the full potential of their Urus.

Enhanced Pressure

The FX-350 is engineered to deliver fuel at an impressive 35Mpa, a significant upgrade from the FX-200’s 25Mpa. By applying the principle Q=PxA (flow rate = pressure x nozzle area), the FX-350 increases fuel flow by 40%, ensuring your Lamborghini Urus gets the necessary fuel for optimal combustion, even under extreme performance conditions.

What’s Included in the Kit?

• 2 x FX-350 upgraded high-pressure fuel pumps
• 1 x Ethanol Content Monitor kit (optional), with mobile app
• 1 x Bosch spec 10-micron high-flow Fuel Filter

Spool 10-micron filter

Ensures superior filtration, protecting your Lamborghini Urus's high-pressure pump and injectors from debris without causing pressure drops in the low-pressure fuel system.

Spool Ethanol Content Monitor

The Spool ECA kit offers real-time ethanol content and fuel temperature monitoring via a mobile app. Utilizing BLE 4.0 technology, it wirelessly connects to your smartphone while remaining compatible with other Bluetooth devices. The fuel lines are black nylon-coated, braided steel with a PTFE core, ensuring full E85 compatibility.

Are Tune Changes Required?

Yes, the FX-350 requires calibration adjustments to avoid potential damage. Detailed calibration information is provided for your tuner, and we can recommend experienced tuners familiar with the FX-350 upgrade. Custom tuning is essential to fully optimize the FX-350 for your Lamborghini Urus and its specific setup.

Low-Pressure Fuel Pump Upgrade

To protect your high-pressure pump and injectors, ensuring proper low-pressure fueling is critical. Insufficient low-pressure fueling can damage the pump and void warranties. Make sure your fuel system upgrades include low-pressure pump improvements when necessary.

We recommend the torquebyte controller to increase your factory low pressure pump's output by 60% to make sure the hpfp is always receiving sufficient low side flow. Please visit
