FAQ

Q1: How do I confirm this 7135-108 kit is compatible with my specific DPA pump?
A1: Compatibility is based on the part number stamped on your original pump or its housing. The primary reference numbers are 7135-108 or 7135108. We strongly recommend consulting your pump’s service manual or a qualified diesel technician to verify the correct repair kit before purchase.

Q2: What tools or expertise are required to install this spring kit?
A2: Replacing internal components of a DPA fuel injection pump requires specialized knowledge, clean working conditions, and specific calibration tools. This task should only be performed by a trained diesel fuel injection specialist to ensure proper reassembly, timing, and calibration for safe and efficient engine operation.

Q3: What are the symptoms that indicate a failing spring in a DPA pump?
A3: Worn or fatigued springs within the DPA pump can lead to inconsistent fuel pressure. Common symptoms include engine power loss, difficulty starting, rough or unstable idle, increased fuel consumption, and excessive black or white exhaust smoke. If these issues are traced to the injection pump, internal component repair with a kit like the 7135-108 may be required.
