Probably first things to check are that the water drain on the filter is closed, that the WIF sensor is secure in the filter and that the filter is tight to the filter head and the o-ring is sealing properly. Hopefully in going thru the filter setup like that you'll find your air leak.

My 2001 did the same thing. There is a small filter on top of the engine that was defective. They found it by putting dye in tank and driving until it showed. Your dealer should be aware of this filter.

The service department has a detailed procedure to detect fuel system leaks ... It is spelled out in the service manuals ...


Good luck let us know what you find out ...
