Fuelab 53501-5 Mini Adjustable Fuel Pressure Regulator EFI

The Fuelab 535 Series Mini Adjustable Fuel Pressure Regulator delivers professional-grade fuel system control in a compact, lightweight package. This EFI-specific regulator weighs 50% less than Fuelab's 515/525 series while maintaining all the performance features that professionals demand.

Key Features:

• Compact mini design ideal for tight engine bay installations
• Adjustable fuel pressure range suitable for fuel injected applications up to 125 PSID
• -6AN return port located on the bottom for standard configurations
• Accepts both port style and non-port style union fittings without interference
• Precision-engineered for consistent fuel pressure regulation
• Lightweight aluminum construction reduces overall weight by 50%
• Compatible with gasoline and alcohol-based fuels

This 535 Series regulator features a bottom-mounted return port configuration. For applications requiring in-line return port placement, see the 545 Series variant which positions the return port in-line with the inlet for installations in extremely confined spaces. Ideal for EFI swaps, performance builds, and racing applications where space and weight are critical factors.
