Fuelab 54502-1-G Series Mini Fuel Pressure Regulator EFI In-Line - 545

The Fuelab 545 Series Adjustable Mini Fuel Pressure Regulator delivers precision fuel pressure control in a compact, lightweight design that weighs 50% less than the standard 515/525 series regulators. This in-line fuel pressure regulator is specifically engineered for electronic fuel injection (EFI) systems, offering the same professional-grade performance as larger units in a space-saving package.

Key Features:

• Compact mini design weighs 50% less than standard series regulators
• In-line return port configuration allows installation in extremely tight locations
• Return port positioned in-line with inlet port rather than on the bottom for improved clearance
• Accepts both port style and non-port style union fittings without interference
• Adjustable pressure range designed for EFI applications
• Precision-machined aluminum construction for durability and corrosion resistance
• High-flow design maintains consistent fuel pressure under demanding conditions

The 545 Series distinguishes itself from the 535 Series through its unique inline return port configuration. While the 535 features a -6AN return port on the bottom, the 545's inline return port design makes it ideal for installations where vertical clearance is limited or when a streamlined fuel line routing is preferred. This regulator supports fuel injected applications and provides reliable, adjustable fuel pressure control for performance and racing applications.
