40-75 PSI Adjustable Range:

The 40-75 PSI adjustable base pressure range accommodates a wide variety of fuel injector and engine combinations. Most naturally aspirated applications run 43-58 PSI base pressure, while forced induction applications may require higher base pressure depending on injector specifications. The wide adjustment range ensures compatibility with virtually any EFI system requiring precise fuel pressure control.

1:1 Boost Reference:

The 1:1 vacuum/boost reference capability is critical for forced induction applications. When connected to manifold pressure, the regulator automatically increases fuel pressure 1:1 with boost pressure, maintaining consistent fuel pressure differential across the injectors. This ensures proper fuel delivery and prevents lean conditions under boost. For naturally aspirated applications, the vacuum reference improves fuel economy and idle quality by reducing fuel pressure at idle and cruise.

High Flow Design:

Aeromotive's high-flow design ensures the regulator doesn't become a restriction in your fuel system. The A1000 regulator supports A1000 class and smaller fuel pumps, providing adequate flow for medium to high horsepower applications. The dual -6 AN inlet ports allow for flexible plumbing configurations, while the -6 AN return port efficiently routes excess fuel back to the tank.

ORB Port Design:

The AN spec ORB (o-ring boss) port design provides leak-free connections using -6 AN ORB fittings. ORB fittings use an o-ring seal rather than tapered threads, eliminating the need for thread sealant and providing more reliable sealing. The ORB design also allows for easier installation and removal compared to NPT fittings, making fuel system maintenance simpler.

Next Generation Design:

This next-generation A1000 regulator features a redesigned body profiled for reduced size and weight while maintaining the legendary Aeromotive flow and pressure control. The deep, bright-dip black anodized finish on the cap and base provides corrosion resistance and a premium appearance. The distinctive design also serves as a visual cue that you've purchased a genuine Aeromotive regulator, not an inferior knock-off or counterfeit component.

Fuel Compatibility:

The A1000 regulator is compatible with gasoline, ethanol (E85), methanol, and diesel fuels. The internal components are engineered to withstand the corrosive properties of alcohol-based fuels, making this regulator suitable for flex-fuel and race fuel applications. This versatility ensures the regulator can handle whatever fuel your application requires.
