Aeromotive 13129 Adjustable EFI Bypass Fuel Pressure Regulator

This EFI Bypass Regulator encompasses features and benefits only found on Aeromotive regulators and in a new smaller and lighter package. Capable of supporting applications up to 1000 HP, the 13129 EFI Bypass Regulator can handle high-flow EFI fuel pumps and the most aggressive street machines; especially those looking for a cleaner, lighter solution where performance is critical or where space is a premium. Base pressure adjustable from 40-75 psi. Fuel pressure rises on a 1:1 ratio with boost. Provides (2) ORB-06 inlet/outlet ports and (1) ORB-06 return port. 1/8? NPT gauge port. Bright Dip Black Anodized Finish. Vacuum boost port. CNC-Machined 6061 T6 billet aluminum construction. Regulator - EFI Bypass, Adjustable (2) -6 inlets, (1) -6 bypass. EFI bypass regulator; adjustable from 30-70 PSI; smaller and lighter with consistent performance

The Aeromotive 13129 EFI Bypass Fuel Pressure Regulator delivers consistent fuel pressure control for high-performance electronic fuel injection systems. Designed to support applications producing up to 1,000 horsepower, this compact regulator is well suited for high-flow EFI fuel pumps, aggressive street cars, and race-oriented builds where dependable performance and efficient packaging are essential.

Base fuel pressure is adjustable from 40 to 75 psi, while the regulator maintains a 1:1 fuel-pressure rise with boost for accurate fuel delivery under changing engine loads. Two ORB-06 inlet ports and one ORB-06 bypass return port provide flexible plumbing options. A vacuum/boost reference port supports forced-induction applications, and the 1/8-inch NPT gauge port allows convenient fuel-pressure monitoring.

Built from CNC-machined 6061-T6 billet aluminum, the Aeromotive 13129 features a durable Bright Dip Black anodized finish and a smaller, lighter design than many conventional EFI regulators. Its compact construction helps simplify installation in tight engine compartments without sacrificing the consistent pressure control expected from Aeromotive components. This regulator is intended for EFI applications and is not approved for carbureted systems.

What's Included: One Aeromotive 13129 adjustable EFI bypass fuel pressure regulator.
