Aeromotive EFI Fuel Pressure Regulator 40-75 PSI | Bypass Return, ORB-06 Inlets, 1/8" Gauge Port | 13129

Overview

The Aeromotive EFI Bypass Regulator is a compact, high‑performance fuel pressure regulator designed for modern agile engines. Built from CNC‑machined 6061‑T6 billet aluminum, it blends aerospace‑grade tolerances with three generations of track engineering to deliver dependable pressure control in a lighter, space‑savvy package. With a 40‑75 psi adjustable base pressure and boost‑referenced 1:1 pressure rise, this regulator supports high‑flow EFI pumps and engines up to 1000 HP, making it a versatile choice for both street machines and aggressive builds where space is at a premium.

In a practical, return‑style layout, the unit offers two ORB‑06 inlet ports and one ORB‑06 return port, designed to simplify routing of fuel lines in crowded engine bays. A dedicated 1/8" NPT gauge port gives you a direct reading point for pressure monitoring, so tuning and diagnostics can happen without unnecessary disassembly. The combination of compact form, robust materials, and a proven design makes it easier to keep fuel delivery consistent as boost and engine demands change.

What it does well

• PRECISION EFI FUEL PRESSURE CONTROL: Maintains stable 40‑75 PSI and supports high‑flow pumps up to 1000 HP.
• COMPACT RETURN LINE REGULATOR LAYOUT: Two ORB‑06 inlets and one ORB‑06 return port enable clean routing in tight engine bays.
• MONITORING READY: A dedicated 1/8" NPT gauge port allows accurate pressure checks and tuning adjustments on‑the‑go.
• BOOST-REFERENCED PERFORMANCE: Pressure rises on a 1:1 ratio with boost for responsive fueling under load.
• BUILT FOR RELIABILITY: Aerospace processes and in‑house engineering underpin a durable, track‑tested regulator.

Real‑world use cases

For turbocharged or supercharged builds where fuel pressure must follow boost curves, this regulator offers a predictable path to stable fueling. In tight engine bays or vehicles with high‑flow pumps, its compact return layout helps keep hoses organized while preserving performance. The gauge port makes routine checks straightforward, helping you verify pressure as part of regular service or during tune sessions.

Who benefits

Drivers and builders seeking a lighter, space‑friendly regulator without sacrificing flow or control will find value in this Aeromotive solution. It suits high‑HP street machines and track‑ready builds where clean routing and reliable, monitorable fuel pressure are priorities.
