FAQ

Q: What does the “A-type” designation mean for this plunger?
A: The “A-type” refers to a standard plunger and barrel assembly design commonly used in inline fuel injection pumps. The model “A89” specifies the exact plunger diameter and lead geometry required for precise fuel metering. It is a direct replacement part for pumps using this specific A-type configuration.

Q: How can I verify this plunger fits my injection pump?
A: Please cross-reference the OEM number 131151-7320 (or 1311517320) with your existing pump’s part number. The physical size is standard, but the plunger’s helix and diameter are specific to the A89 model. If you are unsure, please contact our 24-hour customer service with your pump model for compatibility confirmation.

Q: What maintenance is required when replacing this plunger?
A: When replacing the plunger, it is highly recommended to also replace the corresponding delivery valve and inspect the barrel for wear. The injection pump must be properly cleaned to prevent contamination. After installation, the pump timing and fuel delivery must be recalibrated on a test bench by a qualified technician to ensure optimal engine performance.
