IN-TANK FUEL PUMP SUPPORT UNIT AND ASSEMBLY

摘要

IN-TANK FUEL PUMP SUPPORT UNIT AND ASSEMBLY A fuel pump assembly for use with a fuel tank having an access opening in the top includes a fuel pump support unit comprising an access opening cover, a rigid conduit projecting through the cover and a bracket including a plurality of arms attached to the rigid conduit and supporting a generally horizontal circular seat below the lower end of the rigid conduit. An axial flow fuel pump with a cylindrical body, an annular flange and inlet and outlet openings at opposite axial ends is supported in the seat by an annular resilient member with the inlet near the bottom of the tank and the outlet near the lower end of the rigid conduit. The annular flange prevents the pump from falling through the seat but allows the pump to be pushed upward out of the seat when subjected to forces from below. A resilient conduit normally connects the pump outlet with the lower end of the rigid conduit; and a gauge sender and float unit may be attached to one of the bracket arms. The access opening cover may further include a vapor outlet.
