King Adjustable Fuel Pressure Regulator for Injection Specifications

Replacing the standard pressure regulator with an adjustable model is an easy way to improve the performance of a standard injection system. The King Rising Rate regulator features a progressive, non-linear base pressure variation for the same vacuum or boost pressure value.

This progressive control enriches the mixture as engine speed increases, while maintaining stable idle speed. Designed to maintain constant fuel pressure regardless of load and driving conditions, this regulator also ensures high flow and particularly precise pressure control.

Ideal for modified vehicles, sports or racing use, this King regulator guarantees stable pressure within the system, even when the engine is switched off. Manufactured from a specific alloy using a high-quality moulding process, it is meticulously assembled by hand. Each unit is individually tested to ensure reliable operation and optimum precision.
