Spool Performance FX-170 Stage 2 Upgraded High Pressure Pump [VR30DDTT]

The Spool Performance FX-170 is a Stage 2 upgraded high-pressure fuel pump engineered for the VR30DDTT engine platform. It features an enlarged bore that provides approximately 340 liters per hour (LPH) of flow on the factory fuel pump lobe, offering a significant increase over stock.

This pump is fully E85 compatible and designed to be plug-and-play. No cutting, splicing, or custom fabrication is required for installation. It supports high ethanol content blends and is capable of fueling larger turbo configurations reliably.

Why Choose the FX-170:
The factory high-pressure fuel pump on the VR30DDTT platform is a major limitation when increasing power output. The Spool FX-170 eliminates that bottleneck by providing increased flow capacity for upgraded turbo applications and ethanol blends.

Key performance gains include:

• Supports high ethanol blends including E85
• Enables safe tuning for bigger turbo systems
• Improves fueling stability under high load
• Direct replacement with plug-and-play installation

Low Pressure Fuel Pump Upgrade Required:
High-pressure fuel pumps and direct-injection injectors depend on consistent low-pressure fuel delivery. Inadequate low-pressure fueling causes pump piston and bore wear, as they rely on internal fuel flow for lubrication. Failure due to low-side starvation is easily detectable and voids warranty coverage. Spool Performance recommends pairing the FX-170 with a proper low-pressure fuel pump upgrade to ensure full performance and system reliability.
