    Vacuum hose diagram

    I'm not 100% sure what hoses/lines I need to change to prevent future
    so called "vacuum leaks" nor have the part number for them.

    I possibly need to change the EGR as well.

    Here's some of the diagrams I found. But I still got no OEM part number for the lines
    The part numbers in the link gets me no where..

    Why not just get lengths of vacuum line from the parts store of proper size?

    Well they original are molded plastic lines. So I'm concerned about the self cut silicone lines getting pinched in the sharp angles.
