Fuel rail for injection system

An arrangement for supplying high pressure fuel to a plurality of fuel injectors, said arrangement comprising:

• a housing defining a fuel chamber, said fuel chamber provided with a flow inlet from a high pressure fuel source and forming a first portion of flow path of the fuel, said fuel chamber being fluidly connected to a conduit providing a second portion of flow path, said conduit having a plurality of outlets adapted to provide flow of high pressure fuel from said fuel chamber via said conduit to said plurality of fuel injectors via respective first outlet flow conduits, wherein said second portion of flow path is substantially narrower than said first portion of flow path, and including a pressure sensor located in or adjacent to said conduit, where said conduit is in the form of a toroidal pipe.
