The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of a main fuel pump, identified by NSN 7R-1680-016738195-F7, with a quantity of one unit required for delivery FOB origin. This procurement involves a commercial/nondevelopmental/off-the-shelf item that is critical for flight operations, necessitating government source approval prior to contract award due to the technical data not being adequate for full and open competition. Interested vendors must provide the necessary documentation for source approval as outlined in the NAVSUP WSS Source Approval Information Brochures, and proposals must be submitted within 45 days of the notice publication. For further inquiries, interested parties can contact Charles F. Horan at (215) 697-1303 or via email at CHARLES.F.HORAN@NAVY.MIL.
