(57) A spray nozzle extention (100) is affixed to the output of a conventional spray gun
apparatus (26) to allow an operator to spray a polymeric elastomer into enclosed spaces
of an integral fuel tank cavity such as to form an in situ tank within the cavity.
The nozzle tip (50) is extended from the spray gun by a flexible hose (40) and the
complete unit includes variously arranged in-line filter and swivel connectors (38,58,88,80)
to achieve dispersion of lumps in the spray material and axial, yaw, and pitch rotation
of the nozzle tip (50) respectively.
