    It may be hearing the fuel injectors firing. DI is a lot more noisey than port injection. If it is the "tick, tick tick" sound it is most likely the injectors and not the HPFP

    I'm hearing it after my truck is already warmed up.

    Sometimes I hear mine after warm but it's a slight ticking vs an ominous tick/knock

    All I can say is if I'm inside the truck and I have everything off, and I recorded the interior sounds with my phone and then uploaded it to YouTube


    You guys would all be cranking your volume up or thinking it was on mute.

    I don't know what that sound actually is but I'm amazed I can hear it inside your truck.
