What does a fuel pressure regulator do?
A fuel pressure regulator controls fuel pressure within the fuel system so the fuel delivery system can operate within its intended pressure range. It is an important component of many performance and motorsport fuel systems.
Why use an adjustable regulator?
An adjustable regulator allows fuel pressure to be set for the specific engine and fuel-system configuration. The correct pressure target depends on the engine, injectors, ECU strategy and overall fuel-system design.
