Fuelab 54502-1-T Series Mini Fuel Pressure Regulator TBI In-Line - 545

The Fuelab 54502-1-T is a 545 Series adjustable mini fuel pressure regulator designed for throttle body injection (TBI) applications with in-line mounting. This compact regulator delivers the same performance features as Fuelab's 515/525 series while being significantly smaller and weighing 50% less, making it ideal for space-constrained installations.

Key Features:

• Mini design weighs 50% less than standard 515/525 series regulators
• Accepts both port style and non-port style union fittings without interference
• In-line return port configuration aligns with inlet port for tight space installations
• Adjustable pressure range suitable for carbureted applications as low as 10 PSID up to fuel injected systems at 125 PSID
• 545 Series design eliminates bottom-mounted return port for improved clearance
• Precision-engineered for consistent fuel delivery and accurate pressure control

The 545 Series distinguishes itself from the 535 Series with its strategic return port placement in-line with the inlet port rather than on the bottom, allowing for easier installation in extremely tight engine bay locations where clearance is critical.
