Review HOLLEY Quick Fuel Technology Qft Hp Double Pumper All Aluminum Strip fits STREET 850

Introducing the Holley SPHP850-QFT Fuel System, a high-performance double pumper solution designed for street applications demanding up to 850 horsepower. This fuel system is an excellent choice for those who desire reliable and consistent fuel delivery for their high-horsepower vehicles.

The Holley SPHP850-QFT Fuel System is a complete package that includes a 16-inch AFX Pro-Jector fuel pump, a high-pressure regulator, an in-tank fuel pressure sensor, and a wiring harness. The Pro-Jector pump is a double-pump design, which means it utilizes two individual pumps working in unison. This design offers numerous advantages over a single-pump setup. First, it provides increased fuel capacity for better power delivery under heavy load conditions. Second, it ensures consistent fuel pressure, even when engine RPMs vary.

The Pro-Jector pump is also notable for its efficient design. It features a high-performance, magnetically driven impeller that delivers an impressive 1,000 gallons per hour (GPH) at 15 psi. This superior flow rate ensures that your engine receives an ample fuel supply, even during high-demand situations. Additionally, the pump is designed to be self-priming, eliminating the need for external priming methods.

The Holley SPHP850-QFT Fuel System is also equipped with a high-pressure regulator that maintains the desired fuel pressure within the system. This regulator is adjustable from 0 to 125 psi, allowing you to fine-tune the fuel pressure to suit your specific engine setup and driving conditions.

An in-tank fuel pressure sensor is also included in the system. This sensor monitors the fuel pressure and sends real-time data to your vehicle's electronic control module (ECM) for precise fuel delivery control. This feature is essential for maintaining optimal engine performance and maximizing fuel efficiency.

The wiring harness included with the Holley SPHP850-QFT Fuel System is designed to be easy to install and connect to your vehicle's electrical system. It features a plug-and-play design, with each connector clearly labeled for easy identification and installation. The harness is also equipped with a fuel pressure switch, which allows you to easily monitor fuel pressure using a gauge or your vehicle's ECM.

In summary, the Holley SPHP850-QFT Fuel System is a comprehensive and powerful solution for high-horsepower street applications. Its double-pump design ensures reliable and consistent fuel delivery, while its efficient and self-priming Pro-Jector pump offers superior flow rates. The included high-pressure regulator, in-tank fuel pressure sensor, and wiring harness make for a seamless installation process.
