Isuzu 8-97605946-8 High Pressure Fuel Pump — Common Rail HP3
The Isuzu 8-97605946-8 (Denso 294050-0423) is the OEM common rail high pressure fuel injection pump for Isuzu 6HK1 and 4HK1 diesel engines. This HP3-type pump generates the extremely high fuel pressure required by the common rail direct injection system — typically 160–180 MPa. A failing pump causes hard starting, low rail pressure fault codes, power loss, and rough running.
