Nissan Patrol 5.6 VK56VD V8 High Pressure Fuel Pump Internals Upgrade (single)

In many cases we see the factory fuel pump begin to suffer from pressure loss.
The limitation of how much volume of fuel the high pressure pump can flow is dependent upon the volume displaced by the pressurizing cylinder inside the pump.

In order to address the lack of fuel ,and power outputs never stop increasing we developed th HPFP UPGRADE KIT to suits everybody's build needs, we developed upgrade kit to suits everybody's build needs and the first company who designed and implement a working bigger kit/size available to customers around the world with
LIGHTER THAN OEM
                                         
                                                  
It has 20% more surface area and is capable of OVER 150bar+ of pressure star,and ending with over 50% volume and UP TO 190bar+ and less weight by 10% comparred to OE (fuel pressure is dependant to type of engine as it fits many applications)
This monster is ready for big turbo applications or just for stock power giving another 15 bar fuel rail pressure and some extra hp especially in mid range
Piston head is optimized for ideal hydrodynamic flow . The surface is hardened and heat treated in 2 different stages

It's being tested on many configurations and different hardware/software setups around the globe and have proven again and again the reliability and performance you can expect from each and every HPFP Upgrade kit.
