The A1000 fuel pressure regulator is designed for EFI return-style fuel systems and is ideal for motorsport, drag racing and other high-performance applications. Its high-performance design ensures precise fuel pressure regulation and a stable fuel supply, even under demanding operating conditions.

The regulator features a 1:1 vacuum/boost reference, meaning fuel pressure increases in direct proportion to boost pressure. This maintains a consistent pressure differential across the injectors, providing accurate fuel delivery for both naturally aspirated and turbocharged engines.

The housing is manufactured from anodized aluminum and is compatible with gasoline, E85 and alcohol-based fuels. The integrated 1/8" NPT port allows easy installation of a fuel pressure gauge or pressure sensor.
