Fuelab 54502-5-G 545 Series Mini Fuel Pressure Regulator EFI Inline

The Fuelab 545 Series Adjustable Mini Fuel Pressure Regulator delivers professional-grade fuel system control in a compact, lightweight design. This EFI inline regulator is engineered for electronic fuel injection applications, providing precise pressure adjustment up to 125 PSID while weighing 50% less than Fuelab's standard 515/525 series regulators.

Key Features:

• Compact mini design perfect for tight engine bay installations
• Inline return port configuration aligned with inlet port for maximum clearance
• Accepts both port-style and non-port-style union fittings without interference
• Adjustable pressure range suitable for EFI applications up to 125 PSID
• 50% lighter than comparable full-size fuel pressure regulators
• -6AN inlet and return ports for secure, leak-free connections

The 545 Series features a unique inline return port design that distinguishes it from the 535 Series (which has a bottom-mounted return). This inline configuration makes the 54502-5-G ideal for installations where space is at a premium, allowing the regulator to fit in extremely tight locations while maintaining easy access for adjustments. Precision-machined construction ensures consistent fuel pressure delivery for optimal engine performance and reliability.
