FAQ

Q1: How do I verify this pump transfer is compatible with my injection pump?
A: Please check the part number stamped on your existing pump transfer unit. If it matches any of the numbers listed (7139-223, 7139-540, 7139-541, 7185-469), this part is a direct replacement. If the number is different, please contact our support team with your pump model and serial number for cross-verification.

Q2: What are the common symptoms of a failing DPA pump transfer unit?
A: Common signs include hard starting, engine misfiring or surging at low RPMs, a loss of power under load, and fuel leaks around the pump. A faulty transfer pump cannot maintain correct internal pressure, leading to poor fuel atomization and combustion.

Q3: Is any special installation or calibration required after replacing the transfer pump?
A: The replacement is a mechanical swap. However, after installation, it is critical to bleed the fuel system to remove air. For optimal performance, we recommend checking and adjusting the static injection timing on the engine after the repair, as specified in the engine service manual.
