Thanks man. My vehicle is 2003 E39 530i. It's second hand car,so I have no idea what appened to this part.There is question (suspicion) in my mind, it appears to be a RETROFIT (Rigged). On my 2001 525i e39 I have an F connector located on top of my boot almost opposite yours. Is your vehicle an E38?
Thanks man!!The other end of this hose should go into the Sucking Jet Pump. http://www.realoem.com/bmw/enUS/showparts?id=DT53-USA-05-2003-E39-BMW-530i&diagId=11_2885
Thanks man! And I found this, pretty helpfull! http://www.bimmerfest.com/forums/showthread.php?t=578766on earlier models, the sucking jet pump is direct to the air inlet tubing, the regulator vac line comes off of the CCV..on later models. the CCV port is capped, and the f connector is used.
