A grounded fuel delivery module for a fuel system of a vehicle includes a fuel reservoir and a fuel pump disposed in the fuel reservoir and adapted to pump fuel from a fuel tank of the fuel system to an engine of the vehicle. One embodiment of the present invention includes a memory array decoder circuit. The drain-proof ring is an O ring and is arranged in a stepped recess of the valve disk to seal the waterproof washer; the drain-proof ring is symmetric to the axis of the ring. In an alternate embodiment, the circuit board traces that leave the differential signal vias are disposed in one layer of the circuit board above a wide ground strip disposed on another layer of the circuit board. The correlation is performed by regressing the seismic data sample points with sample points from the model function using a least squares technique to determine the regression gradient for the graphic point. The lamp is mounted in the aperture and the rear wall of the casing carries a metal plate.
