The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 25 units of the Fuel Pump Assembly (NSN 7R-1680-016622898-LU, REF NR 4952456). This procurement requires engineering source approval due to the flight-critical nature of the item, necessitating that only approved sources may submit proposals, as the technical data and manufacturing knowledge are not readily available to the Government. Interested parties must provide detailed documentation as outlined in the NAVSUP Source Approval Information Brochures, and proposals must be submitted with all required data to be considered for award. For further inquiries, potential bidders can contact Marisa L. Tetkowski at (215) 697-2644 or via email at MARISA.TETKOWSKI@NAVY.MIL.
