A fuel pump arrangement has multiple fuel pumps for fitting to aircraft fuel tanks and allowing maintenance of the pumps without requiring access from inside the tanks, particularly one having a housing with two fuel pumps for mounting in or adjacent a single aperture in the wall of a fuel tank, each pump being individually removable from the housing by withdrawal away from the tank. A sleeve is moveable also in the same direction as the pump to obstruct inlets in the housing and isolate the housing from the fuel in the tank so the tank need not be drained.
