Spool Performance FX-350 Stage 3+ Upgraded High Pressure Pump [VR30DDTT]

Unlock the full performance potential of your VR30DDTT engine with the Spool Performance FX-350 Stage 3+ High Pressure Fuel Pump System. Designed for high-output builds, this upgraded fuel pump delivers up to 400 LPH of fuel flow with a 350 Bar pressure rating, surpassing the limitations of the stock high-pressure fuel pump (HPFP). The FX-350 pump increases your engine's fueling capacity by 80%, allowing for safe operation with higher ethanol concentrations and supporting bigger turbos for additional power gains.

This plug-and-play upgrade requires no cutting or splicing, making installation straightforward while significantly enhancing fuel delivery to support advanced tuning and increased horsepower. When combined with IFX-22 injectors, it delivers exceptional fuel flow, improving atomization for more efficient combustion and helping unlock even greater power.

Why You Need the FX-350:

The stock high-pressure fuel pump on the VR30DDTT engine is restrictive, limiting fuel flow and potential power output, especially when upgrading the turbo or running high ethanol blends. The FX-350 addresses this by providing an 80% increase in fuel flow, allowing for higher turbo setups and more aggressive tunes. The pump also supports 350 Bar of fuel pressure, which significantly reduces injector duration and increases overall combustion efficiency.

Key Features:

• 400 LPH Fuel Flow: Upgraded pump delivers up to 400 liters per hour of fuel flow, vastly improving fueling capacity for high-output builds.

• 350 Bar Pressure Rating: Supports increased fuel pressure for better injector performance and reduced injection time.

• E85 Compatible: Fully supports high ethanol concentration fuels, ensuring maximum flexibility for performance tuning.

• IFX-22 Injector Compatibility: Works seamlessly with IFX-22 injectors, allowing for an additional 40% more fuel flow, completely eliminating injector limitations.

• Increased Combustion Efficiency: Enhanced atomization of fuel contributes to more efficient combustion, unlocking more horsepower.

• Plug-and-Play Installation: No cutting or splicing required, ensuring a smooth and straightforward installation process.

Kit Contents:

• 1 x FX-350 Stage 3+ upgraded high-pressure fuel pump

• 1 x Bosch spec 10-micron high-flow fuel filter

• Upgraded fuel lines (braided steel nylon core, 100% E85 compatible)

• All necessary installation hardware

Spool 10-Micron Filter Unit:

The included 10-micron filter unit provides the best filtration available for the VR30 platform, ensuring your high-pressure fuel system is protected from contaminants without causing any noticeable pressure drops in the low side fuel system. This filter helps maintain the integrity of your high-pressure pump and injectors, preventing damage from debris and ensuring long-lasting performance.

Spool Ethanol Content Monitor:

Monitor in-tank ethanol content and fuel temperature with the Spool Ethanol Content Monitor. The system includes a mobile app for real-time digital readouts via Bluetooth Low Energy (BLE 4.0), allowing you to track ethanol concentration and fuel temperature directly on your device. This system also includes a 0-5V output for flex-fuel implementation, providing additional flexibility for tuning your VR30DDTT engine. The fuel lines used in the kit are compatible with E85, ensuring durability under high ethanol conditions.

Low Pressure Fuel Pump Upgrade:

Adequate low-pressure fueling is critical for the proper functioning of high-pressure pumps and injectors in direct injection (DI) systems. Without proper low-pressure fueling, you risk damage to the high-pressure pump's piston and bore. Spool Performance recommends upgrading your low-pressure fuel system to ensure durability and avoid potential warranty voids. Always plan your fuel system build carefully to avoid issues related to low-pressure fueling.
