FIELD: aeronautics; aviation; cosmonautics.
SUBSTANCE: present invention relates to fuel pump arrangements including multiple fuel pumps for fitting to aircraft fuel tanks and allowing maintenance of said pumps without requiring access from inside the tanks. Fuel pump arrangement 100 is shown, comprising housing 102 including two fuel pumps 140 for mounting in or adjacent single aperture 121 in the wall of fuel tank T. Each pump is individually removable from the housing by withdrawal away from tank T. Sleeve 150 is moveable also in the same direction as the pump to obstruct inlets 120 in housing 102 and isolate the housing from the fuel in tank T.
EFFECT: tank does not have to be emptied when removing the fuel pumps, which makes maintenance easier.
