FAQ

Q1: How can I confirm this delivery valve fits my fuel injection pump?
A: Please compare your current part number with our listed OEM numbers (A57, A91, 12a, 32a, etc.). The valve is a standard size (2x2x2 cm) and is designed for universal fitment in most in-line and distributor pumps. If you are unsure, please contact our 24-hour customer service with your pump model for verification.

Q2: What is the installation procedure for this delivery valve?
A: Installation should be performed by a qualified diesel mechanic. The process involves removing the old valve from the pump head, cleaning the seat, and installing the new valve with the correct torque. It is critical to ensure the seating surface is clean to prevent fuel leaks and maintain injection pressure.

Q3: What maintenance is required for these delivery valves?
A: Delivery valves are wear items and generally require replacement when fuel pressure drops or engine performance degrades. There is no routine maintenance required beyond ensuring the fuel system is free of contaminants. Using high-quality fuel filters will extend the life of the valve.
