Ultra Flow Fuel Pump
Elevate your Hyundai N’s performance with our Ultra Flow Fuel Pump—a complete redesign that goes far beyond an OE upgrade. Now featuring a brand new CNC machined body, fully reworked internals, and a bespoke pressure regulator which is far more capable than the factory or 2GTA0 version, every component is precision engineered to deliver maximum fuel flow and reliability.
Building on the 2GTA0 pump (with a 9.9mm piston), our Ultra Flow Pump features an 11.67mm piston—a substantial upgrade from the original 8.9mm. This translates to a boost of +31.2% over the OE pump.
At its core is a DLC-coated piston that minimizes wear and tear, coupled with an optimally designed spring and cam lobe rocker. The result is a pump that delivers both high fuel flow and unmatched efficiency under extreme pressures.

| Piston Diameter (mm) | 8.9 | 9.9 | 11.67 |
| % Increase vs OE | - | +11.2% | +31.2% |
Percentage increases are calculated relative to the original 8.9mm piston.
Frequently Asked Questions
Our Ultra Flow Fuel Pump is a complete redesign featuring an 11.67mm piston—compared to the 8.9mm piston in the OE pump and 9.9mm in the 2GTA0. In addition, it now boasts a brand new CNC machined body, fully reworked internals, and a bespoke pressure regulator that is far more capable than both the factory and 2GTA0 versions. This results in a performance boost of +31.2% over the OE pump.
The DLC (Diamond-Like Carbon) coating minimizes wear and tear on the piston, ensuring a longer service life and consistent performance even at high pressures.
No tuning is necessary for basic operation, but combining the pump with tuning solutions unlocks even more performance—especially under high ethanol blends and extreme conditions.
