FUEL MANIFOLD (CB 104)
The fuel manifold is secured to the inside of
the inlet manifold, and its function is to send
fuel to the fuel injectors.
The fuel manifold consists of an aluminium
casting and it incorporates the seats for the fu­
el injectors and pressure regulator.
The fuel inlet comprises an attachment with
tapered sealing screw.
The fuel is recirculated by means of a pipe
contained in the manifold and connected at
one end to the regulator, and at the other end
to the external fuel return pipe to the tank.
