    Hi,

    Long story very short, I've an N75 which has two connectors on, one labelled out and one labelled VAC, If I use a mityvac on the "out" port this doesn't even try to hold a vacuum, this appears normal, however when I hold 10hg on the VAC port this very very slowly leaks/bleeds should this be the case or should the VAC port hold 100% of the VAC without loss?

    Car is an Audi A4 2.0TDI Quattro 170 BRD engine.

    Thanks in advance
