Abstract

A fuel rail for internal combustion engines utilizing fuel injectors which includes an elongate housing having an internal chamber with a fuel inlet near one end and a fuel outlet leading to a pressure regulator valve. The chamber is divided longitudinally by a flexible metal membrane which absorbs pulsations created by the injectors and stabilizes the fuel supply to the fuel injectors.
