    Do I need to prime my mechanical fuel pump?

    Re: Do I have to prime mechanical fuel pump? Yeah, a good pump will prime itself a lot faster on a running engine than at cranking speed. A weaker pump may well run the engine well enough but be unable to prime. Any leakage at valves will greatly handicap things, as will wear at several points that can reduse stroke. via

    How do you prime an in tank fuel pump?

  • Disconnect the hose that connects the fuel pump to the carburetor.
  • Spray a three second burst of starting fluid into the carburetor.
