The Department of Defense, through the Defense Logistics Agency (DLA Land Warren), is seeking to award a contract for the Tank, Fuel Engine, which is a source-controlled item exclusively available from Robertson Fuel System LLC. The procurement requires specialized technical and engineering expertise to meet the design space requirements and Critical Item Product Function Specification for the Tank, Fuel Engine, as the government lacks the necessary technical data for competitive procurement. Interested parties must note that this is a Sources Sought notice, not an open solicitation, and qualification testing is required to become an approved source, which does not guarantee future business opportunities. For further inquiries, interested vendors can contact Derek T. Rutkowski at derek.rutkowski@dla.mil or by phone at 586-467-1202.
