Yes, took a peek in the AMM. It is not very clear but the Centre tank scavenge pump and the Centre tank Water scavenge pump are linked. It looks as though with the Centre Tank scavenge system running, liquid is sucked through the centre tank water scavenge lines as well. The centre tank scavenge jet pump motive power comes from the wing booster pumps.
Steve....
I think I'm looking at the same blurry picture from the AMM, but enlarging it, I don't see the CT water scavenge system hooked up to wing tank pumps. So, with the CT O/J pumps OFF, I don't see the CT
water scavenge system operating.
However, the scavenge pickups for fuel and water in the CT appear to be very close together on the schematic. If they are at the same
height... what liquid the CT
fuel scavenge system will be pumping would depend on what's in the CT (water, fuel, melted ice/slush)
