Fuelab 54502-4-T Series Mini Fuel Pressure Regulator TBI In-Line - 545

The Fuelab 545 Series Adjustable Mini Fuel Pressure Regulator delivers professional-grade fuel system control in a compact, lightweight design. Weighing 50% less than the standard 515/525 series regulators, this miniaturized unit is engineered for tight installations where space is at a premium.

Key Features:

• In-line return port configuration positions the return port in-line with the inlet port rather than on the bottom, ideal for cramped engine compartments
• TBI (Throttle Body Injection) application support with adjustable pressure range
• Compatible with both port style and non-port style union fittings without interference
• Compact mini design reduces weight by 50% compared to standard Fuelab regulators
• Adjustable pressure control for precise fuel system tuning
• -6AN inlet and return ports for secure, leak-free connections
• Durable construction with precision-machined components

This regulator is part of Fuelab's 535/545 series, which supports a wide range of applications from carbureted engines (as low as 10 PSID) to fuel injected systems (up to 125 PSID). The 545 series distinguishes itself with its in-line return port design, making it the preferred choice when installation space is limited and bottom-mounted return ports would create clearance issues.
