Angier,

Hard to tell from the youtube, but are you absolutely sure that it's not the relay clicking?

Hey, I've just uploaded 3 short video clips to YouTube, the audio is all that matters here.
Up cycle 1
Down cycle
Up cycle 2
My pump has begun to make very odd sounds, especially on the retract cycle.
On liftoff and with the gear coming up, it almost sounded as though a fuel transfer pump had come on and was sucking air.
There is the normal quantity of fluid in the system.
Pump sound sick, any idea what's going on?

Thanks,
