An apparatus for cleaning a tank that is to be installed below the fill line of a tank includes a housing sealably attached to a sidewall of a tank, and a tubing having a flexible output end positioned within the housing such that the output end of the tubing extends past the sidewall of the tank. A control linkage is slidably positioned within th e housing. The control linkage is connected to the flexible output end of the tubing. The control linkage is movable between an extended position and a retracted position. The orientati on of the flexible output end of the tubing is changed as the control linkage is moved between positions, such that the direction of fluid flowing out of the flexible outp ut end of the tubing is also changed. A seal is provided for sealing the tubing and the control linkage within the housing. |
