This makes it a great option for both street usage and performance applications.
  • Question: How do I install the Melling M390 oil pump?

    Answer: Installing the Melling M390 oil pump requires some mechanical skills and tools. Start by removing the oil pan and existing pump, ensuring that any debris is cleared.
