Vehicle Compatibility and Return Conditions.

This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.

Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.

Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.

Reference Information

Fuel Pressure Regulator, 529 Series Electronic, Inline, Return Style, 25-90 psi, Billet Aluminum, Red Anodized

FUELAB 529 Series electronic fuel pressure regulators work directly with the FUELAB Prodigy line of fuel pumps to reduce heat build-up and vapor lock conditions related to street/strip operation. Set the pressure mechanically like a traditional bypass regulator and let their demand-based speed control take care of the rest! These regulators generate a signal to the pump to control the return line flow rate. This feature reduces current draw while at low engine output to prevent fuel overheating--which could lead to system failure.

Additional info:
• Designed for use with FUELAB® Prodigy fuel pumps (41401,41402,41403,42401, and 42402 only)
• Patented method for demand-based flow control; able to detect changes in demand before change in rail pressure is realized
• Automatically reduces current draw at low flow demand
• Additional analog output to track actual fuel system capacity
• Independent system--no other connections, control boxes, or calibration required
• Gasoline, diesel, methanol, and ethanol fuel compatible
• Billet aluminum construction with anodized finish
• Fine thread pitch for precise pressure adjustment
• Versatile mounting bracket and stainless steel hardware
• 1/8 in. NPT gauge port with plug for external pressure gauge
• 1/8 in. NPT pressure reference port with barbed fitting
