Fuelab 53501-4 Mini Adjustable Fuel Pressure Regulator EFI

The Fuelab 535 Series Adjustable Mini Fuel Pressure Regulator delivers professional-grade fuel pressure control in a compact, lightweight package. Weighing 50% less than the 515/525 series while maintaining the same proven performance features, this regulator is engineered for EFI applications where space and weight are at a premium.

Key Features:

• Compact mini design weighs 50% less than standard Fuelab regulators
• Accepts both port-style and non-port-style union fittings without interference
• -6AN return port located on bottom for clean installation
• Adjustable pressure range suitable for fuel injected applications
• Precision pressure control up to 125 PSID
• High-quality construction with anodized aluminum body
• Direct replacement for applications requiring reliable fuel pressure regulation

This 535 Series model features a bottom-mounted return port configuration. For tight-space installations, 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 ideal for modern EFI systems, custom builds, and performance applications where mounting space is limited.
