Quick Fuel Technology Fuel Injection Pressure Regulator

Quick Fuel Technology Fuel Injection Pressure Regulators: Race-Proven Fuel Control

When consistent, accurate fuel pressure is critical to your engine's performance, Quick Fuel Technology (QFT) delivers solutions built on decades of motorsports engineering. Fuel injection pressure regulators are the unsung workhorses of any high-performance fuel system — they maintain steady delivery pressure to the injectors across all RPM ranges and load conditions, and QFT's lineup is engineered to meet that demand without compromise.

A Fuel System Specialist's Approach to Pressure Regulation

Quick Fuel Technology approaches pressure regulation the same way it approaches every component in its catalog: with real-world race experience baked into the design. Their fuel injection pressure regulators are available in both cast aluminum and machined billet aluminum variants, giving builders a choice between proven economy and premium construction depending on the demands of their build.

QFT's billet aluminum regulators stand out for their use of high-quality internal components. Key construction features include:

• Fluorocarbon diaphragms and Viton® O-rings for long-term chemical resistance and a reliable seal
• Stainless steel pins, brass valve guides, and hard-coat anodized diaphragm plates for durability under sustained high-pressure operation
• Ball and stem activation with a high-quality GFLT diaphragm assembly for steady, consistent fuel flow
• An 1/8" NPT port for manifold vacuum or boost reference, enabling real-time pressure compensation in forced-induction applications
• A dedicated port for a fuel pressure gauge, keeping your data front and center during tuning sessions
• Laser-cut stainless steel mounting bracket and hardware included for easy installation

Broad Pressure Range and Multi-Fuel Compatibility

QFT's regulator lineup covers a wide operating range to suit everything from mild street builds to all-out competition engines. Adjustable output pressure can be set as low as 1.0 psi for low-pressure carbureted applications, while high-pressure billet units are preset at 7 PSI and operable within the 4.5–9 PSI range for demanding EFI and carbureted setups. Two-port regulators are rated to support engines up to 650 hp, while four-port configurations are designed for builds exceeding that threshold.

A standout advantage of Quick Fuel Technology's regulators is their broad fuel compatibility. Products are engineered to work with gasoline, alcohol, methanol, and E85 — an essential consideration for performance builders who may switch fuels between seasons or events. Select billet models are also compatible with QFT billet fuel pressure regulator logs, allowing seamless integration with the rest of the QFT fuel system ecosystem.

Built for Real-World Plumbing Flexibility

QFT regulators are available with both NPT and AN O-ring inlet/outlet ports, accommodating virtually any fuel line configuration. Whether you're running a return-style or a non-return fuel system, and whether your pump is a steady-state electric or a variable-output mechanical unit, there is a QFT regulator designed for that application. This flexibility makes them a natural fit for custom street rods, drag cars, oval track builds, and high-performance street machines alike.
