summary: FMCSA withdraws its January 16, 2026, notice that requested public comment
  on an application from Charles Machine Works, Inc. (CMW) seeking renewal of a five-year
  exemption from the Agency's prohibition against the use of gravity-fed or siphon-fed
  fuel systems on commercial motor vehicles (CMVs). FMCSA has determined that the
  Agency's February 19, 2026, final rule titled "Parts and Accessories Necessary for
  Safe Operation; Auxiliary Fuel Tanks," provided the requested relief by amending
  the relevant regulation in a way that resolves the concerns outlined in CMW's original
  exemption request. Consequently, the exemption is now unnecessary, not only for
  CMW but also for any other entities that might have planned to request an exemption
  from the prohibition on gravity-fed or siphon-fed fuel systems on CMVs.
