Cummins is recalling tens of thousands of B6.7 engines for an issue with the fuel system, according to National Highway Traffic Safety Administration documents.

On April 3, NHTSA published a recall acknowledgement document to Cummins regarding B6.7 diesel engines, part number D313029BX03. Engines with fuel module option number FS90301 or FS90453 are affected.
