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

The Spool FX-350 is an advanced high-pressure fuel pump designed to significantly enhance the fueling capacity of the VR30DDTT engine platform. Featuring a larger bore size, this pump delivers approximately 400 LPH of fuel flow and up to 350 bar of pressure, dramatically improving combustion efficiency. The innovative high-efficiency flow pathways decrease injection duration times through the same injectors at higher pressures. Paired with Spool’s IFX-22 injectors, this setup allows for an additional 40% fuel flow while maintaining dynamic control for low-load stability. The FX-350 is fully E85 compatible and designed as a plug-and-play solution with no cutting or splicing required. With this pump, you can achieve higher ethanol concentrations and support larger turbo setups, unlocking even greater performance potential.

Why Choose the FX-350?

The factory high-pressure fuel pump (HPFP) on the VR30DDTT engine is a limiting factor when tuning for higher output. The FX-350 provides roughly 80% more fuel flow, enabling bigger turbo applications and higher ethanol content blends. With the ability to deliver 350 bar of pressure, this pump enhances combustion efficiency, leading to increased horsepower and engine performance.

Key Features:

• 400 LPH fuel flow capacity
• Supports up to 350 bar of pressure
• E85 compatible
• Fully plug-and-play, no cutting or splicing required
• Paired with IFX-22 injectors for 40% more fuel flow
• Optimized for bigger turbo setups and high ethanol concentrations

Spool 10-Micron Fuel Filter:

The included 10-micron filter ensures optimal filtration without causing a noticeable pressure drop. This filter unit protects the high-pressure pump and injectors from debris, ensuring durability and longevity.

Spool Ethanol Content Monitor:

The FX-350 includes the Spool Ethanol Content Analyzer (ECA) kit, featuring a digital readout of ethanol content and fuel temperature via the Spool mobile app. The ECA utilizes Bluetooth 4.0 low-energy technology, allowing you to monitor ethanol content without interrupting other Bluetooth functions. The kit also includes a 0-5V filtered output for flex-fuel applications and braided steel nylon core fuel lines that are 100% E85 compatible.

Low-Pressure Fuel Pump Upgrade:

To ensure proper functioning of the high-pressure pump, it’s crucial to have an upgraded low-pressure fuel pump. Insufficient low-pressure fueling can cause damage to the high-pressure pump and void warranties. Plan your fuel system build carefully, especially when adding performance components.
