FAQ

Q1: How do I confirm this part is compatible with my diesel fuel pump?
A1: The surest method is to match the part number. Locate the identification tag or stamped number on your existing DPA fuel pump or its original rotor. Cross-reference it with our listed part numbers: 7123-345M, 7180-559M, or the consolidated OE 7123345M7180559M. If in doubt, contact our technical support with your pump model.

Q2: Is this a complete assembly or just the rotor?
A2: This product is the complete Head Rotor Assembly, which includes the central rotor and its associated head components as a single, ready-to-install unit for the specified DPA pump models.

Q3: What are the signs that my DPA head rotor needs replacement?
A3: Common symptoms include hard starting, uneven engine idle or misfiring, loss of engine power, excessive black or white smoke from the exhaust, and increased fuel consumption. These indicate wear in the rotor and head, leading to improper fuel distribution and pressure.
