Fuelab 54502-3-G Series Mini Fuel Pressure Regulator EFI In-Line - 545

The Fuelab 54502-3-G is a 545 Series adjustable mini fuel pressure regulator designed for electronic fuel injection (EFI) systems in an in-line configuration. This compact regulator delivers the same high-performance features as Fuelab's 515/525 series while being significantly smaller and weighing 50% less, making it ideal for tight engine bay installations.

Key Features:

• Compact mini design weighs 50% less than standard 515/525 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
• Accepts both port style and non-port style union fittings without interference
• Adjustable pressure regulation for EFI applications up to 125 PSID
• Precision machined aluminum construction for durability and heat dissipation
• -6AN inlet and outlet ports for optimal flow capacity

The 545 Series features an inline return port design that distinguishes it from the 535 Series (which has a bottom-mounted return port). This configuration makes the 54502-3-G particularly well-suited for applications where vertical clearance is limited or where routing the return line from the bottom would be difficult. Built to Fuelab's exacting standards, this regulator provides consistent, reliable fuel pressure control for high-performance EFI systems.
