Abstract: Improved apparatus for supplying fuel to one or more fuel injectors used to inject fuel into a combustion engine. In the preferred form, each of the fuel injectors has its discharge port positioned in the engine intake manifold and a clamp retains the injector in position thereon. The clamp has a first portion that has a passage for receiving the inlet conduit to the fuel injector. Also, this portion of the clamp has inlet and outlet passages in communication with the passage receiving the injector inlet conduit so that fuel supplied to the inlet passage flows into the inlet conduit of the fuel injector and also flows out of the outlet passage. A second portion of the clamp is used for securing the clamp to the engine intake manifold. The fuel injector is located between the first portion of the clamp and the intake manifold. Flexible conduit may be used to connect the outlet passage of one clamp with the inlet passage to another clamp.
