    The stainless is the compressor output line. I was referring to the compressor air intake line. The blue one in pics.Compressor is turbo charged with filtered air, via the intake manifold, It may be leaking at compressor, very hard to see or get to. But possible.

    Follow that blue hose from manifold to compressor, see if it’s broken at compressor

    If you look closely at the pic the OP posted, you can see a huge hole in that hose directly under the red wire loom.

    Did you put any kind of lube on the pipes and boots? Should be put together dry.

    I've honestly always tightened down those clamps until the spring is pretty much compressed. Never had any luck with them at the "proper" torque. Just gotta use some caution on plastic stuff because it'll break.

    Yep, that's the one. On the way to Napa to get a new one. Keep fingers crossed that this solves it.
