As originally built by EMD, the SD90MAC had a fuel tank capacity of 5,700 gallons. While owned by Union Pacific,
the units started developing cracks in the frames around the fuel tank mounts.  UP worked with EMD to solve the
frame cracking problem by adding additional mounting brackets between the frame and fuel tank. In addition, the fuel
filler pipes were modified to only allow a maximum of 4,700 gallons of fuel to be added. All of the former UP units had
this modification when they were delivered to NS. NS did this modification to the former CIT units during rebuilding.
