A system and method for engaging a slide-in mountable fuel pump assembly with a fan cover of an internal combustion engine is disclosed. The fuel pump assembly includes a fuel pump configured to pump fuel from a fuel source to the engine and a mounting bracket affixed to or formed integrally with the fuel pump and configured to slidingly engage a fan cover of the engine so as to enable selective mounting and removal of the fuel pump assembly to and from the fan cover. The mounting bracket further includes a main plate affixed to or formed integrally with the fuel pump and a track formed on each of opposing sides of the main plate, with the track configured to slidingly engage a mating feature formed on the fan cover of the engine so as to selectively mount the fuel pump assembly to the fan cover.
