Fuelab 52502-3 Series In-Line Fuel Pressure Regulator - 525 6AN

The Fuelab 525 Series Fuel Pressure Regulator is engineered for high-performance fuel system applications requiring precise pressure control in compact installations. This adjustable in-line regulator features a unique design with the return port positioned in-line with the inlet port rather than on the bottom, enabling installation in extremely tight engine bays and chassis locations.

Key Features:

• Adjustable pressure range: 4-12 PSI (carbureted applications) or up to 125 PSID depending on configuration
• -6AN inlet and -6AN return port in-line configuration for space-saving installation
• Compatible with gasoline, diesel, methanol, and ethanol fuels
• Precision-machined billet aluminum construction with Type II military-spec anodizing (MIL-A-8625)
• Fine thread pitch adjustment mechanism for precise pressure tuning
• 1/8 NPT gauge port with plug for external pressure gauge monitoring
• 1/8 NPT pressure reference port with barbed fitting for vacuum/boost referencing
• Includes versatile mounting bracket and stainless steel hardware
• CARB compliant for legal use in all 50 states
• Accepts both port style and non-port style union fittings without interference

The 525 Series regulator is ideal for carbureted and fuel-injected performance applications where space is limited and precise fuel pressure control is critical. Backed by Fuelab's 2-year limited warranty.
