Adj EFI Regulator w/2 10an Inlets - Black

The Aeromotive Adjustable EFI Regulator with dual 10 AN inlets is a precision fuel pressure control component designed for modern fuel-injected engines running gasoline or E85 ethanol blends. This in-line regulator maintains consistent fuel pressure between 40 and 75 psi, delivering stable supply to EFI systems where pressure stability directly impacts fuel atomization, combustion efficiency, and overall engine performance.

The regulator features 10 AN female O-ring inlets for primary fuel supply and a 6 AN female O-ring return line, with an additional 1/8 inch NPT gauge port for monitoring actual system pressure. The dual inlet configuration allows parallel fuel line routing for high-flow applications, while the adjustable design enables tuning to specific fuel system requirements. Black anodized aluminum construction resists corrosion while maintaining a lightweight profile at 1.1 pounds. The compact dimensions (5.5 x 2.8 x 5.7 inches) facilitate installation in tight engine bay configurations common to retrofit and custom builds.

This regulator serves builders and technicians working on fuel-injected conversions, carbureted-to-EFI retrofits, and performance fuel system upgrades. Dual-inlet design accommodates high-volume fuel pumps or redundant pump configurations found in racing and high-output applications. The 40–75 psi range covers standard GM LS EFI, modern Ford Coyote platforms, and common aftermarket EFI controllers. E85 compatibility expands options for ethanol-blend fuel users seeking consistent pressure regulation across fuel type variations.
