Detailed Product Description

The Delphi HM10045 direct injection high pressure fuel pump is specifically designed for gas-fueled engines in Audi and Volkswagen vehicles such as the A6 Quattro, A8 Quattro, Q7, R8, S5, and Touareg. Its mechanical operation ensures consistent fuel pressure necessary for direct injection systems. The pump features a robust metal housing finished in silver, providing durability and resistance to engine bay conditions. Both the inlet and outlet connections are threaded, with the inlet fitting sized M12-1.5 and dual outlet fittings sized M14-1.5, facilitating secure and leak-free fuel line connections. The pump is externally mounted on the right side of the engine compartment and uses blade-type terminals with two male connectors for electrical integration. This standard replacement part does not include mounting hardware, gaskets, or wiring harnesses, so these components must be sourced separately if needed.
