FAQ

Q1: How do I confirm this Delivery Valve (A40) fits my fuel injection pump?
A: First, check the model number on your existing delivery valve; it should be stamped as “A40”. Secondly, verify the OEM number (131110-5920 or 1311105920) matches your pump’s service manual or the old part. If your pump uses this specific valve model, it will be a direct replacement.

Q2: What are the signs that my delivery valve needs replacement?
A: Common symptoms include hard starting, especially when the engine is hot, uneven engine idle (misfiring), a decrease in fuel economy, and black smoke from the exhaust due to incomplete combustion. A faulty delivery valve can also cause fuel pressure fluctuations within the injection pump.

Q3: What maintenance is recommended when replacing this part?
A: When replacing the delivery valve, ensure the sealing surface inside the pump housing is perfectly clean and free of debris. Always use a new sealing washer (if applicable) and tighten the valve holder to the manufacturer’s specified torque to prevent fuel leaks. It is also a good practice to replace the delivery valve holders or retainers if they show signs of wear or damage.
