Precision Raceworks In-Line Micro Regulator - 6 Bar

Product Details

For enthusiasts seeking to regulate fuel pressure at the engine without the complexities of manual adjustments or the need for a 1:1 boost reference, a preset fuel pressure regulator offers an ideal solution. These compact regulators are designed for straightforward installation and consistent performance.

Key Features:

• AN6 Input and Output Fittings: Compatible with all female AN6 flare fittings by removing the included O-rings, or with most AN6 ORB female fittings and ports by retaining the pre-installed O-rings.
• Zero Bubble Seal: Ensures an airtight seal, preventing pressure bleed-down after the fuel pumps shut off. This design maintains line pressure, reducing the risk of long engine cranks, misfires, and startup stumbles commonly associated with other regulators.
• High Flow Capacity: Equipped with one of the largest internal dump ports on the market, this regulator responds swiftly to sudden pressure changes, ensuring stable fuel delivery.
• 100% E85 Compatibility: Constructed with materials resistant to ethanol exposure, this regulator maintains its sealing capability and accuracy over time, even with consistent use of E85 fuel.

Installation Advantages:

The preset regulator can be easily integrated by teeing off your existing fuel feed line or threading directly into any AN6 female fitting or most AN6 ORB female ports. A return line is then routed back to the tank. This eliminates the need for bulky regulators, custom mounts, or manual pressure adjustments, simplifying the installation process.

Considerations:

While these regulators are precisely set, it's essential to match the fuel pump's output with the engine's demand. Excessive fuel volume can exceed the regulator's capacity, leading to higher-than-target pressures. For optimal performance, modern vehicles employ pump speed control (PWM) to align fuel volume closely with engine requirements. This approach, combined with an accurate regulator, ensures stable fuel pressures, reduces heat input into the fuel, and enhances both horsepower and fuel economy.

By opting for a preset fuel pressure regulator, you achieve a balance of simplicity and efficiency, ensuring reliable fuel pressure management without the need for ongoing adjustments.
