Engineered for Motorsports & Race Use
maximum power & long-term durability
Built as part of Stanadyne’s new GX Series of GDI performance pumps, the RGX represents the pinnacle of race-focused fuel system engineering.
Unlike modified OE service pumps, the RGX is purpose-built from the ground up to safely deliver the extreme pressure, flow, and durability required by modern high-horsepower engines.
For builders, tuners, and race teams pushing their platforms to the limit, the RGX provides the fuel delivery foundation needed to unlock the next level of performance.
Purpose-Built Performance
The RGX fuel pump was developed specifically for high-output racing engines that demand reliable fuel delivery under the most aggressive operating conditions.
Maximum Fuel Volume
At the core of the RGX pump is Stanadyne’s proven Goliath large-plunger GDI architecture, featuring a 12-millimeter plunger and high-lift design.
For Modern Platforms
The GX Series was engineered to support many of today’s most popular high-performance vehicle platforms, including applications from Mercedes-AMG, Ford, BMW, GM, and Stellantis.
