Fuel system accessories enhance power delivery and optimize vehicle performance. Beyond core components like pumps or injectors, performance accessories such as voltage boosters, tuning modules, and pressure regulators ensure consistent fuel flow under demanding conditions. These products are key to achieving stable horsepower, supporting fuel tuning, and maintaining precision under boost or load.

Fuel system accessories are performance-focused components that help regulate and refine fuel delivery. Items like Boost-A-Pumps, tuners, wiring upgrades, and voltage controllers enhance how efficiently the system delivers fuel to the engine. They work alongside major components to increase flow, stabilize pressure, and improve throttle response, essential for modified and high-output applications.

Performance accessories include fuel voltage boosters, pressure regulators, tuning devices, and upgraded wiring harnesses. Each product fine-tunes system behavior for better efficiency and consistent performance under higher loads. Using the right accessories helps unlock horsepower potential, prevent lean conditions, and ensure the entire fuel system supports your vehicle’s performance goals.

A weak or inconsistent power signal, fluctuating fuel pressure, or poor tuning response may indicate underperforming accessories. Loss of voltage under load, unstable AFRs, or hesitation at high RPMs can point to failing boosters or controllers. Upgrading to quality performance accessories restores steady fuel delivery and safeguards your investment in pumps and injectors.
The ideal performance accessory depends on your setup and horsepower goals. Voltage boosters, tuners, and data-driven control systems each serve unique roles in optimizing output. Matching accessories to your fuel system ensures consistent pressure, proper calibration, and seamless integration with existing upgrades like injectors, pumps, and engine management software.

OEM accessories restore factory performance, but performance upgrades take fueling to the next level. Products like Boost-A-Pumps and HP Tuners increase voltage and enable precision calibration for higher horsepower. These solutions support forced-induction, ethanol, and other demanding setups that exceed OEM limits while maintaining reliability and control.

Choosing compatible accessories is crucial for safe and efficient operation. Voltage boosters and tuning modules must match your pump type, electrical system, and ECU. Direct-fit designs simplify installation and maintain OEM integration, while universal systems offer flexibility for custom builds when properly configured and tuned.

Comprehensive accessory bundles provide everything needed for consistent performance, including wiring solutions, voltage controllers, and sensors. These assemblies ensure all components communicate seamlessly and deliver optimized results. Designed for convenience and reliability, full kits make it easy to upgrade or expand a performance fuel system.
Proper setup and calibration are key when installing performance fuel system accessories. Following manufacturer guidelines ensures accurate voltage delivery, safe wiring, and stable fuel pressure. Periodic checks and recalibrations help maintain efficiency and prevent data or flow inconsistencies under load or boost conditions.

Install voltage boosters, regulators, or tuners using dedicated power and ground paths to avoid electrical interference. Ensure connections are secure and insulated from heat. Calibrate tuning devices according to vehicle specifications and verify output through data logging. Correct setup guarantees reliable performance and maximum fuel delivery efficiency.

Inspect wiring, sensors, and connectors periodically for corrosion or loose fits. Keep firmware and calibration software updated to maintain compatibility with new fuel blends or ECU versions. Proper maintenance of accessories ensures consistent performance, stable AFRs, and optimal voltage support for high-demand systems.

Common issues include inconsistent voltage, poor fuel delivery, or erratic tuning data. These may stem from weak electrical connections or outdated calibration files. Checking wiring integrity and re-tuning with the latest software often restores optimal performance, preventing power loss and maintaining consistent pressure under boost.
Upgrading to performance accessories like Boost-A-Pumps, HP Tuners, and high-flow regulators improves consistency and responsiveness. These products deliver the precise fuel control required for high-horsepower and forced-induction builds, ensuring clean data, stable pressure, and reliable power at every RPM.

Advanced accessories, including voltage boosters and fuel management modules, stabilize fuel delivery at high output levels. They eliminate lean spikes and pressure drops, supporting clean power curves and enhanced throttle response. These upgrades are vital for performance-oriented builds that demand precise and reliable fueling.

Performance fuel pumps depend on accessories to perform at their peak. Voltage boosters, tuners, and upgraded wiring ensure steady current and consistent flow, preventing drop-off under load. Pairing these components maximizes fuel pump potential and extends the life of your entire fuel system.

Even in performance systems, durable sealing and connection components are critical. High-temperature, ethanol-resistant O-rings, and pressure-rated fuel lines maintain system integrity under demanding conditions. These essentials complement tuning accessories by ensuring the mechanical side of the system keeps pace with upgraded electronics.

Full performance kits bring together compatible voltage, tuning, and sealing solutions to simplify upgrades. Designed for efficiency and reliability, they ensure balanced fuel flow and voltage control across the system. A complete kit saves time, improves power delivery, and supports both daily and competitive performance needs.
Quantum offers a wide range of fuel system accessories from trusted brands such as Kenne Bell, HP Tuners, AEM, and Dragy. These include performance-enhancing products like Boost-a-Pump systems, methanol injection kits, performance meters, and tuning devices.
Many of the fuel system accessories we offer, such as HP Tuners and the Dragy performance meter, are designed for easy DIY use. However, products like the Boost-a-Pump or methanol injection kits may require professional installation for optimal results and safety.
The Kenne Bell Boost-a-Pump increases the voltage to your fuel pump, boosting fuel flow without needing a larger pump. This is ideal for supercharged or turbocharged engines where additional fuel delivery is necessary to support higher performance levels.
Since many fuel system accessories are designed for high-performance or custom applications, the Year, Make, Model search tool may not provide accurate results. The best way to determine compatibility is by reviewing the product specifications and installation requirements listed on the product page.
