SAAS SR1002 Fuel Pressure Regulator Adjustable EFI - Polished
The SAAS SR1002 is a premium return-style fuel pressure regulator designed for installation after the engine injector rail. This regulator maintains consistent fuel pressure across varying boost conditions, ensuring optimal fuel delivery for both naturally aspirated and turbocharged applications.
Key Features
- 1:1 Rising Rate Technology - For every 1 PSI increase in boost pressure, fuel pressure increases by 1 PSI, maintaining constant pressure differential between injector inlet and outlet
- Billet CNC Aluminum Construction - Precision machined from high-grade aluminum with polished finish for durability and aesthetics
- Universal EFI Compatibility - Accommodates both standard and aftermarket EFI fuel pumps
- Professional Port Configuration - Includes inlet port for fuel from injector rail, outlet port for optional fuel pressure gauge, and low-pressure return line port
- Auxiliary Gauge Port - Features 1/8"-27 NPTF auxiliary port, ideal for SG100 Series Fuel Pressure Gauge
- Complete Fitting Kit - Includes 1/4" line fittings for easy installation
- Fuel Compatibility - Compatible with ethanol-based fuels
Technical Specifications
- Operating Range: 200-650 kPa (30-95 PSI)
- Minimum Flow at Outlet: 300 LPH (80 GPH) using Bosch 040 EFI pump as benchmark
- Adjustment: 360-degree top nut adjustment for precise pressure control
- Style: Return-style regulator (not bypass-style)
- Applications: Turbo and naturally aspirated engines
- Finish: Polished aluminum
This regulator is essential for maintaining proper injector operation, as injectors are solenoid valves that require precise pressure differentials to function correctly. Too high fuel pressure can prevent injector solenoids from opening fully, causing fuel starvation.
