Fuelab 53502-2-G 535 Series Mini Fuel Pressure Regulator

The Fuelab 535 Series Adjustable Mini Fuel Pressure Regulator delivers professional-grade fuel system control in a compact, lightweight package. Weighing 50% less than the 515/525 series while maintaining all the same premium features, this regulator is engineered for TBI (Throttle Body Injection) and other fuel delivery systems where space and weight are critical factors.

Key Features:

• Compact mini design weighs 50% less than full-size 515/525 series regulators
• -6AN return port located on the bottom for streamlined plumbing
• Accepts both port style and non-port style union fittings without interference
• Adjustable pressure regulation for precise fuel system tuning
• Compatible with carbureted applications as low as 10 PSID
• Supports fuel injected applications up to 125 PSID
• Precision-machined aluminum construction for durability

The 535 Series features a bottom-mounted return port configuration, making it ideal for installations where horizontal space is available. For applications requiring even tighter packaging, consider the 545 Series which positions the return port in-line with the inlet. The regulator's compact footprint and versatile fitting compatibility make it an excellent choice for performance builds, street rods, and motorsports applications where every ounce and inch matters.
