Abstract
Carbon deposits and related residue and contaminants are removed from the fuel ports and internal surfaces of an internal combustion engine fuel system, particularly fuel injectors, carburetors, fuel pumps, fuel passages, and the like, by initially utilizing a priming pump to pump priming fuel to the engine from an external fuel source while the engine is being cranked to start the engine and then utilizing the engine fuel pump to pump a combustible, carbon removing conditioning fuel from the fuel source through the engine fuel system along a flow path which by-passes the priming pump so as to avoid restriction of the conditioning fuel flow by the priming pump and thereby increase the conditioning fuel flow rate sufficiently to permit simultaneous servicing of several engines.
