2003 2.5 whistling/squeal from fuel line/ fuel rail

Replaced plugs and coils, plenum gaskets, brake vacuum line. No codes any more. Loud squealing/ whistling from fuel rail. Sounds like it's coming from the pressure switch block. Can feel the fuel line vibrating and squealing changes when line is wiggled or pressing on fuel rail. Any ideas?

sounds like something wasnt fastened correctly when rebuilding or a vacuum line isnt replaced correctly.
did u remember to replace the rubber vacuum fitting on the back of the intake manifold?
