Engineered to be the Best

We partnered with Nostrum High Performance, one of the industry’s most respected leaders in fuel system engineering, during the development of this component. This collaboration allows our customers to trust that our fuel pumps are among the best built and best performing options available.

Using advanced Computational Fluid Dynamics (CFD), the AMS Performance VR30DDTT Stage 4 High Pressure Fuel Pump was engineered with optimized internal fuel flow trajectories for maximum efficiency. This results in an impressive flow capacity of 440 LPH.

Each AMS VR30 pump arrives fully assembled for a quick, bolt-on upgrade and includes both OEM and AN fuel fittings, along with OEM type electrical connectors for seamless integration. This allows the pump to function properly within the factory system while providing flexibility for custom fuel system setups. Every unit is individually flow tested to verify performance and reliability, and each includes comprehensive installation instructions. The pump is capable of reaching a maximum pressure of 250 bar, delivering the headroom required for high power VR30 applications.

Put it to the Test

What truly sets this, and every AMS component, apart from the competition is our uncompromising commitment to validation. The AMS Performance VR30DDTT Stage 4 High Pressure Fuel Pump has endured a rigorous battery of in-house tests, including countless 1/4-mile and 1/2-mile passes designed to push the system to its limits. Beyond our own research and development efforts, each AMS VR30 High Pressure Fuel Pump is individually bench tested by Nostrum High Performance prior to shipping. Their state-of-the-art quality control process ensures exceptional durability, consistency, and performance long before the pump ever reaches your vehicle. To give you even greater peace of mind, every pump includes a Limited Lifetime Warranty¹ against manufacturer defects at no additional cost.

For a deeper look into the craftsmanship behind these components, we highly recommend watching the behind-the-scenes video below. You will get an inside look at Nostrum’s world-class facility, including their manufacturing, testing, R&D, and quality control processes that help make this fuel pump one of the most reliable and trusted solutions in the industry.

Product Notes

• In order to take full advantage of our HPFP, specific calibrations to your ECU tune file will need to be made. Once the HPFP is installed, the engine will start and run, however a qualified engine calibrator must review datalogs to verify the engine is running properly! Please contact an AMS sales representative to discuss your ECU tuning needs by emailing [email protected].
• Vehicles equipped with an AMS Flex Fuel Kit do not require the additional low pressure feed line. For non-AMS or no flex fuel setups, a -6AN low-pressure feed line is required for HPFP installation. This can be added via the dropdown menu.
• Please be aware there are two separate instruction guide files available for this product. The first is a physical installation guide, and the second is a calibration quick-start guide.
