MG 7 BMW 3 Series Fuel Pump Core DK-146 Low Pressure Fuel Supply Precise Replacement

MG 7 and BMW 3 Series (318Li/320Li) owners, beware: the DK-146 low-pressure fuel pump core is likely the culprit if the vehicle shows starting difficulties, weak acceleration, or rough idle. The pump core sits inside the fuel tank, delivering fuel to the high-pressure pump to ensure accurate fuel pressure. As an OEM replacement part, it uses high-wear-resistant materials and fits MG 7 and BMW 318Li/320Li models. Installation difficulty medium; allow 1.5–2 hours for a professional technician; replacement effectively restores fuel delivery efficiency.
