FAQ

Q: How do I confirm this part is compatible with my specific Denso pump?
A: The most reliable method is to physically inspect the identification tag or casting on your existing HP3 or HP4 pump and match the part number. The numbers 294180-0080, 294180-0090, or 2941800090 should be present. If unsure, consult the vehicle’s service documentation or contact us with your pump’s serial/model number.

Q: Is this a complete pump assembly or just the internal components?
A: This listing is for the rotor and gear set only (internal components of the fuel feed pump). It is designed for technicians rebuilding or repairing an existing Denso HP3/HP4 pump housing, not as a complete ready-to-install pump unit.

Q: What is the recommended procedure for installing this rotor set?
A: Installation should only be performed by a qualified technician familiar with common rail fuel systems. The pump must be completely disassembled in a clean environment. The old rotor set is removed, the pump housing is thoroughly cleaned and inspected, and the new rotor set is installed with proper lubrication and torque specifications. Always refer to the official service manual for the precise procedure.
