Abstract

A connector arrangement for a fluid system includes a fuel injector that defines a first fluid passage having a connector, a pipe that is engageable with the connector of the first fluid passage, preferably to form a high pressure seal, and a nut arranged to connect the pipe to the connector of the first fluid passage. A chamber is defined between the nut and the fuel injector, such chamber serving to collect leaked fluid from the first fluid passage. The fuel injector is provided with a second fluid passage having a first end in communication with the chamber and a second end in communication with a low pressure drain such that leaked fuel is provided with a drain path.
