    On my 2009 K9 EFI. If I have a bad o ring on my fuel cap would this let pressure release from the tank causing my pump to run constantly.

    Did that. Also the bike run great just hear that pump running. If you open the cap when the bike is running will the pump stay on till you close it to build up pressure.

    When you turn the ignition on and pres run button the pump should run for a few seconds and than stop. Now after you start the motor pump will come on and stay on in my opinion.
    Normally you do not hear it running because of the motor noise.
    How can you tell the pump is running all the time with the motor running?

    Paul.
