On Realoem, the only line I find with an upturn is a fuel feed line from the filter/regulator to the engine bay.


Is that a vacuum line? The other line shown is a pressure line, so the engine should be able to run without the "feed line".

I'm having trouble with BMW terminology, technology, and unusual placement of components. I dealt 99% with American cars, 1% foreign cars, and most of them were General Motors cars over the last 5.5 decades. I figured that my first BMW would be a challenge, but looks like I'll have to re-learn everything as I go. oldskewel, at least you've got an eight-year head-start on me, so lead on!
