FAQ

Q: What is the function of the delivery valve in a diesel fuel pump?
A: The delivery valve controls the flow of fuel from the injection pump to the injector. It maintains residual pressure in the fuel line and prevents fuel from dripping after injection, ensuring clean cut-off and efficient engine operation. A worn valve can cause poor starting, misfiring, and reduced power.

Q: How do I know if my MM3/MM6 pump needs a new delivery valve?
A: Common symptoms include hard starting, engine misfiring at low RPM, black smoke from the exhaust, and a noticeable drop in fuel economy. If your pump is being rebuilt or you are experiencing these issues, replacing the delivery valve is a standard and cost-effective repair step.

Q: Is this delivery valve a direct replacement for my existing part?
A: Yes, this is a direct replacement part for standard MM3 and MM6 injection pumps. However, we recommend verifying your pump’s specific model number and comparing the dimensions of your old valve to ensure a perfect fit. The package size is 20x20x20 cm and weighs 0.1 kg.
