I have been trying to locate a suspected vacume/intake leak for the past month now.
It seems that it is coming from the area where the fuel pressure regulator is located. None
of the intake leak symptoms are present, such as strange idle or acceleration issues.
But I can hear it. At the back of the plenum, there is a junction where all
of the black vacume lines meet up. They are all wrapped in this tape
material. Are those vacume lines joined with any type of union back there?
The sound doesn't seem to rise and lower with rpms. I don't get it.
