Description
AEM 25-305BK is a high-capacity universal adjustable fuel-pressure regulator for a compatible return-style system.
A regulator controls pressure by managing return flow. Pump output, return-line restriction, injector requirements, and manifold reference must be evaluated together.
Technical Highlights
- Black anodized finish.
- Two -6 AN / 9/16-18 inlet ports.
- -6 AN / 9/16-18 return connection.
- 1/8-inch NPT gauge/sensor port.
- 40-130 PSI adjustment range.
- 1:1 boost-referenced rising-pressure behavior.
Installation & Compatibility
Verify the mounting arrangement and inlet/return routing. Set base pressure using the prescribed reference condition and a suitable gauge, then check operation under load. An adjustable regulator does not compensate for insufficient pump capacity or an incorrect fuel calibration.
