1. In an automotive vehicle comprising an internal combustion engine and an occupant restraint system that includes a restraint control module for detecting vehicle impact, a fuel delivery system comprising:
- a fuel tank;
an electrical fuel pump disposed within the fuel tank for supplying fuel to said internal combustion engine; and
a fuel control module electrically connected to the electrical fuel pump for regulating operation thereof, further wherein said fuel control module is electrically connected to said restraint control module for receiving a signal indicative of a vehicle impact directly therefrom and adapted to cease operation of said electrical fuel pump in response to said signal.

Abstract
A fuel delivery system includes a fuel control module for regulating a fuel pump within a fuel tank independent of the engine control module. The fuel control module is connected to a restraint control module for receiving a signal directly therefrom in the event of vehicle impact. The fuel control module is adapted to cease fuel pump operation in response to an impact signal without requiring a signal from the engine control module.

5. In an automotive vehicle comprising an internal combustion engine, an engine control module for regulating operation of the internal combustion engine, and an occupant restraint system that includes a restraint control module for providing a signal indicative of a vehicle impact, an electronic returnless fuel system comprising:
-
a fuel tank having an opening;
a fuel pump disposed in the fuel tank and having a duty cycle;
a flange assembly closing said opening; and
a fuel control module mounted in the flange assembly and electrically connected to the fuel pump, said fuel control module being electrically connected to the engine control module for regulating the duty cycle of the fuel pump in response to engine operating conditions, and further wherein the fuel control module is electrically connected to the restraint control module to receive the signal directly therefrom and adapted to cease operation of said electrical fuel pump in response thereto. - View Dependent Claims (6, 7, 8)
