ABSTRACT:
A fuel pump manifold for a fuel delivery system of an automotive internal combustion engine includes a unitary housing with a fluid conduit formed therein. Inlet and outlet ports communicate with the fluid conduit, which are adapted to be connected to the outlet of a fuel pump and a fuel supply line, respectively. The fuel pump manifold further includes a jet pump supply port communicating with the fluid conduit to feed a jet pump of the fuel delivery system. To prevent fuel from draining from the fuel supply line through the manifold, a check valve is disposed within the outlet port. A pressure relief is also disposed within the fuel pump manifold to relieve excessive pressure in the fuel supply line.
