FAQ

Q1: What is the exact function of the 161S2 delivery valve in the fuel injection system?

The 161S2 delivery valve, also known as the oil outlet valve, controls the flow of fuel from the injection pump to the injector. It maintains residual pressure in the fuel line and ensures a precise, quick cut-off of fuel delivery to prevent secondary injection, which is critical for engine efficiency and emissions control.

Q2: How do I confirm that the 161S2 valve is the correct replacement for my engine?

To confirm fitment, please check the part number stamped on your original delivery valve. It should be “161S2”. You can also reference your engine’s service manual. If you are unsure, please contact our support team with your engine model or vehicle VIN, and we will assist you with cross-referencing.

Q3: What is the recommended installation procedure for this valve?

Installation should be performed by a qualified diesel technician. Ensure the work area is clean. Lubricate the new valve with clean diesel fuel before installation. Tighten to the manufacturer’s specified torque using a calibrated torque wrench. It is highly recommended to replace the associated seals and gaskets during installation to prevent leaks. After installation, bleed the fuel system to remove any air before starting the engine.
