The suction pipe is really not all that long. Just imagine the pipe with a screen on the end of it similar to the boost pump pickups. Its attached directly to the engine feed manifold. The check valve is in the pipeline. The pick up point is somewhat low in the tank about 3 or 4 inches above the tank bottom. Its location is the 4th manhole cover outboard from the wing root and probably less than 10 feet inboard of the engine pylon. One would hope that it is still covered by fuel and not full of air even at that point in the flight.
