The fuel pump suppliers say the propellers can crack and deform, partly because they absorb too much fuel and also because of the solvent drying process used during manufacturing. Once deformed, the impellers can disable the pumps and cause a sudden shut down of the engine. The recall is expected to begin at the end of July 2020.
