FAQ

Q1: What is the purpose of the DPA Liner Carbon Blade Set (7123-388)?

This blade set is a critical wear component inside DPA-type diesel injection pumps. It helps regulate fuel flow and pressure. Replacement is necessary when the pump shows signs of wear, such as hard starting, poor fuel economy, or uneven engine running.

Q2: How do I confirm this blade set fits my pump?

Fitment is determined by the pump’s model number, which is usually stamped on the pump housing. The most reliable method is to cross-reference your existing part number (e.g., 7123-388) or to measure the dimensions of your current carbon blades against the standard size provided. If uncertain, contact our 24-hour customer service with your pump’s serial number for verification.

Q3: What is the recommended installation procedure for this blade set?

Installation should be performed by a qualified diesel mechanic. The process involves disassembling the pump head, carefully removing the old carbon blades and liner, cleaning the housing, and installing the new set. It is critical to ensure the blades are oriented correctly and move freely within the liner. After installation, the pump must be re-calibrated on a test bench to ensure proper fuel delivery settings.
