Abstract
A turbine fuel pump assembly draws fuel from a reservoir and supplies that fuel to a combustion engine. The assembly includes an electric motor which drives a fuel pump, all of which is supported in a sleeve. The fuel pump has a guide ring which has a stripper segment for stripping or shearing fuel off of the vanes of an impeller and redirecting the fuel through an outlet port of the fuel pump. The turbine fuel pump assembly can be easily calibrated for improved pumping efficiency via a calibration ring tool which plastically deforms the sleeve externally by producing a dimple upon the sleeve and a corresponding interior protuberance which bears radially inward against a trailing segment of the guide ring to calibrate or move the cantilevered stripper segment against the impeller to a point where fuel stripping is improved and flow through the pump is optimized.
