Malpassi PBV389 Fuel Injection Rising Rate Regulator

Malpassi PBV389 Rising Rate Fuel Pressure Regulator

If you replace the standard fuel pressure regulator with another adjustable model, you can easily improve performances of the standard injection system. With our Rising Rate Regulator the base pressure variation with the same boost vacuum value, is not "linear" but "progressive". You can enrich as rpm increase while keeping a clean idle. It has been designed to provide a costant fuel pressure under any load (from idle to full throttle) and driving conditions, high-flow delivery and superb pressure control. Ideal for modified street cars/motorsport/racing. Fuel pressure will be stable into system even at engine off. Our regulator is manufactured in special alloy by casting, and each unit is assembled by hand and tested to assure accurate working.
