A disengageable, portable, self-contained fluid conduit cleaning device for unclogging fuel lines, plumbing lines or similar fluid conduits has a pneumatic pump, and a pressure delivery tank chamber. Controls alternatively connect the pump to supply either a pressure charge or a partial vacuum to the chamber. A delivery valve connects the chamber to the fluid conduit, to provide sudden pneumatic or hydraulic shocks to impact and break loose clogging material from the fluid conduit.
