A fuel sender unit is provided for delivering fuel from a conventional fuel tank that may have a resilient bottom wall of the type that deflects under a fuel load. The fuel sender unit includes a support fixture mounted on the fuel tank, a sending unit within the fuel tank for pumping fuel in the fuel tank toward a point of use outside the fuel tank, and an extension apparatus for coupling the sending means to the support fixture for relative movement therebetween. The extension apparatus includes a plurality of fluid-conducting telescoping guide tube assemblies. The sending unit includes a pump and a reservoir cup for accumulating an auxiliary supply of fuel within the fuel tank to maintain a substantially uninterrupted supply of fuel to the pump. The sending unit is lowerable to a variety of depths within the fuel tank to reach and pump fuel accumulating in various regions along the bottom fuel tank wall notwithstanding sagging deformation of said bottom wall. The extension apparatus is automatically adjustable using fuel pressure generated by the fuel pump and yieldably biases the pump and reservoir cup assembly against the bottom wall of a fuel tank during fuel pumping activity to maximize recovery of fuel from the fuel tank.
