Here's the RS4 pump showing the infamous Y-fitting and extra unused plastic hose. I had a bolt installed to plug the un-used hose. Please forgive the messy bench..

It's tough to see, but I used the longer un-used plastic branch hose to replace the Y fitting and shorter hose.

Longer hose attached to the right side of the check valve.

Smart move, I've posted about the 6mo's of heartache that caused me.

I'm having some problems that sound similar to what you had. I'm not sure this is my problem but it really needed to be fixed regardless.
thanks

Give me a call if you want to talk more. I don't claim to be a pro at this, but I DID learn a LOT getting my car fixed.
I'm totally slammed between work and the airbox project, but want to hear what your problems are and what you've checked so far.
