Detailed Product Description

The Delphi HM10049 direct injection high pressure fuel pump is designed to meet the fuel delivery demands of modern gas-powered Audi and Volkswagen vehicles. Its mechanical operation ensures consistent fuel pressure necessary for direct injection systems. The pump features a robust metal housing finished in silver, providing resistance to wear and heat. The inlet connection uses a hose bead type with a 0.313-inch outside diameter, while the outlet side includes two female threaded fittings sized M14-1.5, allowing secure attachment to fuel lines. Electrical connections are made via two male blade terminals, supporting straightforward wiring integration. This external pump does not include mounting hardware or gaskets, so these components should be sourced separately if needed.
