Abstract
A method for repairing damage to a fuel pump assembly of a locomotive is provided that includes identifying a void within a fluid cavity of a fuel pump assembly. After identifying the void within the fluid cavity of the fuel pump assembly, the void is cleaned with a cleaning product, and a filler material is inserted within the void. Then the filler material is laser welded to repair the void. After being laser welded, the fluid cavity of the fuel pump assembly is honed.
